  • PHP's SimpleXML not handling &#8217 ; properly

    - by Matty
    I'm parsing an RSS feed that has an &#8217; in it. SimpleXML turns this into a ’. What can I do to stop this? Just to answer some of the questions that have come up - I'm pulling an RSS feed using CURL. If I output this directly to the browser, the &#8217; displays as ’ which is what's expected. When I create a new SimpleXMLElement using this, (e.g. $xml = new SimpleXmlElement($raw_feed); and dump the $xml variable, every instance of &#8217; is replaced with ’. It appears that SimpleXML is having trouble with UTF-8 ampersand encoded characters. (The XML declaration specifies UTF-8.) I do have control over the feed after CURL has retrieved the feed before it's used to construct a SimpleXML element.

  • how to exploit vulnerability in php

    - by Dr Deo
    i have never seen a buffer overflow exploit in live action. supporse I have found a server that seems to have vulnerabilities. Where can i get proof of the concept code preferably in c/c++ to exploit the vulnerability? eg i found this vulnerability Multiple directory traversal vulnerabilities in functions such as 'posix_access()', 'chdir()', 'ftok()' may allow a remote attacker to bypass 'safe_mode' restrictions. (CVE-2008-2665 and CVE-2008-2666). How can i get proof of concept code for educational purposes PS I am a student and my only desire is to learn

  • PHP XML Validation

    - by efritz
    What's the best way to validate an XML file (or a portion of it) against multiple XSD files? For example, I have the following schema for a configuration loader: <xsd:schema xmlns="http://www.kauriproject.org/schema/configuration" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.kauriproject.org/schema/configuration" elementFormDefault="qualified"> <xsd:element name="configuration" type="configuration" /> <xsd:complexType name="configuration"> <xsd:choice maxOccurs="unbounded"> <xsd:element name="import" type="import" minOccurs="0" maxOccurs="unbounded" /> <xsd:element name="section" type="section" /> </xsd:choice> </xsd:complexType> <xsd:complexType name="section"> <xsd:sequence> <xsd:any minOccurs="0" maxOccurs="unbounded" processContents="lax" /> </xsd:sequence> <xsd:attribute name="name" type="xsd:string" use="required" /> <xsd:attribute name="type" type="xsd:string" use="required" /> </xsd:complexType> <xsd:complexType name="import" mixed="true"> <xsd:attribute name="resource" type="xsd:string" /> </xsd:complexType> </xsd:schema> As the Configuration class exists now, it lets one add a <section> tag with a define concrete parser class (much like custom configuration sections in ASP.NET). However, I'm unsure of how to validate the section being parsed. If it possible to validate just this section of code with an XSD file/string without writing it back to a file?

  • MySQLi PHP: Check if SQL INSERT query was fully successful using MySQLi

    - by Jonathan
    Hi, I have this big function that gets a lot of different data and insert it into multiple tables.. Not all the data is always available so not all the SQL INSERT queries are successful. I need to check which SQL INSERT query was fully successful and which wasn't to the do something with this data (like inserting into a log table or similar). Just to give you an example of how I think it can be done: $sql = 'INSERT INTO data_table (ID, column1, column2) VALUES(?, ?, ?)'; if ($stmt->prepare($sql)) { $stmt->bind_param('iss', $varID, $var1, $var2); if ($stmt->execute()) { $success == TRUE; //or something like that } } I'm not completely sure this is the best way and if its always really show if the data was inserted into the table... Any suggestions??

  • PHP PDO MySQL IN (?,?,?...

    - by nute
    I want to write a MySQL statement like: SELECT * FROM someTable WHERE someId IN (value1, value2, value3, ...) The trick here is that I do not know ahead of time how many values there will be in the IN(). Obviously I know I can generate the query on the go with string manipulations, however since this will run in a loop, I was wondering if I could do it with a PDO PreparedStatement. Something like: $query = $PDO->prepare('SELECT * FROM someTable WHERE someId IN (:idList)'); $query->bindValue(':idList', implode(',', $idArray)); Is that possible?

  • PHP mySQL count number of fields not empty

    - by Pez Cuckow
    I have a database of users where they can send messages to other users (up to four) and the ID of the message they sent is in their user row. e.g. Name, Email, Msg1, Msg2, Msg3, Msg4 Pez, [email protected], 1, 55, 42, 5 //Send 4 messages Steve, [email protected], 0, 0, 0, 0 //Send 0 messages Leon, [email protected], 3, 0, 3, 5 //Send 3 messages How in a MySQL query can I get the amount of those message rows that are not empty or not equal to 0, allowing me to order by that? So it would return Pez - 4 Mesasges Leon - 3 Messages Steve - 0 Messages Im my mind something like order by count(!empty(msg1)+!empty(msg2)+!empty(msg3)+!empty(msg4)) Many thanks,

  • Google App Engine: JDO does the job, JPA does not

    - by Phuong Nguyen de ManCity fan
    I have setup a project using both Jdo and Jpa. I used Jpa Annotation to Declare my Entity. Then I setup my testCases based on LocalTestHelper (from Google App Engine Documentation). When I run the test, a call to makePersistent of Jdo:PersistenceManager is perfectly OK; a call to persist of Jpa:EntityManager raised an error: java.lang.IllegalArgumentException: Type ("org.seamoo.persistence.jpa.model.ExampleModel") is not that of an entity but needs to be for this operation at org.datanucleus.jpa.EntityManagerImpl.assertEntity(EntityManagerImpl.java:888) at org.datanucleus.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:385) Caused by: org.datanucleus.exceptions.NoPersistenceInformationException: The class "org.seamoo.persistence.jpa.model.ExampleModel" is required to be persistable yet no Meta-Data/Annotations can be found for this class.

Below is the link to the source code of the maven projects that reproduce that problem: http://seamoo.com/jpa-bug-reproduce.tar.gz Execute the maven test goal over the parent pom you will notice that 3/4 tests from org.seamoo.persistence.jdo.JdoGenericDAOImplTest passed, while all tests from org.seamoo.persistence.jpa.JpaGenericDAOImplTest failed.

  • PHP's PDO Prepare Method Fails While in a Loop

    - by Andrew G. Johnson
    Given the following code: // Connect to MySQL up here $example_query = $database->prepare('SELECT * FROM table2'); if ($example_query === false) die('prepare failed'); $query = $database->prepare('SELECT * FROM table1'); $query->execute(); while ($results = $query->fetch()) { $example_query = $database->prepare('SELECT * FROM table2'); if ($example_query === false) die('prepare failed'); //it will die here } I obviously attempt to prepare statements to SELET everything from table2 twice. The second one (the one in the WHILE loop) always fails and causes an error. This is only on my production server, developing locally I have no issues so it must be some kind of setting somewhere. My immediate thought is that MySQL has some kind of max_connections setting that is set to 1 and a connection is kept open until the WHILE loop is completed so when I try to prepare a new query it says "nope too many connected already" and shits out. Any ideas? EDIT: Yes I know there's no need to do it twice, in my actual code it only gets prepared in the WHILE loop, but like I said that fails on my production server so after some testing I discovered that a simple SELECT * query fails in the WHILE loop but not out of it. The example code I gave is obviously very watered down to just illustrate the issue.

  • PHP calling and displaying CSS in different browser.

    - by user147685
    I'm having problem with CSS where, when I run on Mozilla Firefox the CSS is doing fine. But when I run inside Internet Explorer, the CSS is not working. When I try to change the code in the CSS file, it works otherwise. Mozilla is OK, but Internet Explorer is not. I have an idea calling 2 different CSS. For example, style_IE.css and style_moz.css. Both CSS files will be called from header.html. How can I fix this problem? Is there some code that can distinguish between browsers? Whenever the user is running in Internet Explorer, then style_IE is called if not it otherwise.

  • A PHP script to stream internet radio?

    - by Honus Wagner
    I've been searching and searching and I haven't yet come up with a solution to host my own streaming audio player. I'm looking for a way to host an internet radio player that connects to whatever streams I enter in and plays them. I'm not looking to play my MP3s or anything like that. I'm looking to play content from 181.fm or 1Club.fm, for example. I'd even settle for ShoutCast-only streams. I've been to www.wavestreaming.com but it didnt work for me. I'm guessing its because in the very first box where you enter your website url, it leads in for you: http//www. then you fill in the rest. My site is https:// and does not contain a www. in the URL. I'm guessing that has something to do with it. Any links, suggestions for search topics, or even a brief technical overview of what I should be looking into would be greatly appreciated. Thanks for your time.

  • PHP string manipulation, inside the string

    - by James
    I have string: ABCDEFGHIJK And I have two arrays of positions in that string that I want to insert different things to. Array ( [0] => 0 [1] => 5 ) Array ( [0] => 7 [1] => 9 ) Which if I decided to add the # character and the = character, it'd produce: #ABCDE=FG#HI=JK Is there any way I can do this without a complicated set of substr? Also, # and = need to be variables that can be of any length, not just one character.

  • PHP find first of occurrence of string

    - by mike
    I have a string of data like below and I've been struggling trying to figure out how to split it up so that I can use it efficiently. "United States FirstName: Mike LastName: Wolf City: Chicago" I need to split up the string in to substrings and the list may not always be in the same order. For example it could vary like below: "United States City: Chicago FirstName: Mike LastName: Wolf" "United States FirstName: City: Chicago Mike LastName: Wolf" I need to find which parameter comes first after 'United States'. It could be 'City:', 'FirstName:' or 'LastName:'. And, I also need to know the start position of the first parameter. Thanks in advance!

  • Display MySQL BLOB'd image on webpage without separate script (PHP)

    - by robhardgood
    So I've got some images stored in a MySQL database as BLOB's (I know it's better to just store the directory and do it that way, but this is what I need to do for now) and I need to display them on a webpage. Now, I know how to make a script and give it an image header and pull the img src from there, but I have a lot of images from different places for different uses, so I'd have to make a ton of these scripts and I'd rather not clutter up my files like that. Anyway, does anyone know of a function or something I can use to display the image that will run on the same page?

  • PHP: why is this null different from the other null

    - by matthy
    hi i tried 2 things what should be the same however it my testing says different does anyone know why the only thing i do is put it in a variable... if ($_SESSION[$something] === null) echo("this is null"); $_SESSION[$something] does not exists so it indeed says: "this is null". now look at this $theSession = $_SESSION[$something]; if (theSession === null) echo("this is null"); now it does not say "this is null" while it should be exactly the same right?

  • PHP Site Deployment Suggestion

    - by TheOnly92
    I'm currently quite troubled by the way of deployment my team is adopting... It's very old-fashioned and I know it doesn't work very well. But I don't exactly know how to change it, so please give some suggestions about it... Here is our current setup: 2 webservers 1 database server 1 test server Current deployment adaptation 1. We develop and work on the test server, every changes is uploaded manually to the test server. 2. When a change or feature is complete, we then commit the changes to SVN repository. 3. After committing the changes, we then upload our changes to the first webserver, where there will be a cronjob running every minute to sync the files between the servers. Something very annoying is, whenever we upload a file just as the syncing job starts, the file that is sync-ed will appear corrupted, since it is only half-uploaded. Another thing is whenever there is a deployment fault, it will be extremely difficult to revert. These are basically the problem I'm facing, what should I do?

  • How can I log and retrieve error messages from a client-side desktop app?

    - by KeyboardMonkey
    Update: The service-based answers below are most likely the way to go, I am also curious to see if there are any out-the-box solutions anyone has tried in the field. Our system uses a client-server architecture, and with more clients using it I'm thinking of better ways to log client application errors, and get them sent to us. Currently we just show a simple error message, with a button that preps an email (with the default system email client) and the clients send this on to our support address. This contains extra info like the stack trace. We also tried saving errors to a network share in the company, but I'm not too keen on that archaic solution either. Now there are only two businesses that refer to clients as users, and I'm sure some of ours support both lifestyles, as they just ignore the email button, and sends a full screen-shot wrapped nicely in a word document. Some factors I'm thinking of include A solution to log errors, like the contrived one above, A robust solution; Logging to a SQL database won't work; if that fails too, then what? Is at least semi-automated, preferably to the point where the logs reach my side. It copes with load, our client base is growing and the current solution, and our inboxes, won't hold up. Minimise installing extra 3rd party components on clients, I want to keep the SPOF to a min. I'd love to hear about any experience or suggestions you have on how I can implement such a solution. System Details It's a Microsoft .Net 2 based system with a SQL backend. Some users work remotely over the net, so network shares aren't always available (unless they VPN, which is awesomely slow at any rate). We have users across different companies, their DB's are hosted on-site. We have remote access to 90% of them.

  • PHP: How to dynamically add to http_build_query?

    I have a scraping object basically. I want to be able to add POST variables to it like $obj->addvar('Name', 'Value'); What I have now is this: function addvar($var, $val) { $postvars[] = Array($var=>$val); } function initiate() { $this->q = $postvars; } if(!empty($this->post)) { $this->params = http_build_query($q); } I haven't tested because it's too incomplete, But would my addvar() function work? How on earth do I append a key+value to the array so http_build_query would accept it? IE (this is what I want): $obj->addvar('username', 'abc'); $obj->addvar('password', 'foobar'); $obj->send(); //..
