  • Escaping ’ character in PHP

    - by richard
    Hello, I'm having a hard time trying to replace this weird right single quote character. I'm using str_replace like this: str_replace("’", '\u1234', $string); It looks like I cannot figure out what character the quote really is. Even when I copy paste it directly from PHPMyAdmin it still doesn't work. Do I have to escape it somehow?

  • Convert complex numerical array to associative array [PHP]

    - by user1500412
    I have an array data that look like this : Array ( [0] => Array ( [0] => Name: [1] => John W. [2] => Registration ID: [3] => 36 ) [1] => Array ( [0] =>Age: [1] => 35 [2] => Height: [3] => 5'11" ) [3] => Array ( [0] => Sex: [1] => M [2] => Weight: [3] => 200lbs ) [4] => Array ( [0] => Address ) [5] => Array ( [0] => 6824 crestwood dr delphi, IN 46923 )) And I want to convert it to associative array like this : Array( ['Name']=> John W. ['Registration ID']=> 36 ['Age']=> 35 ['Height'] => 5'11'' ['Sex']=>M ['Weight']=>200lbs ['Address']=>6824 crestwood dr delphi, IN 46923 ) I have no idea at all how to do this, since the supposed to be array column header were also in sequence, so it makes difficult to convert this array. Any help I appreciate, thx.

  • PHP Try and Catch for SQL Insert

    - by meme
    I have a page on my website (high traffic) that does an insert on every page load. I am curious of the fastest and safest way to (catch an error) and continue if the system is not able to do the insert into MySQL. Should I use try/catch or die or something else. I want to make sure the insert happens but if for some reason it can't I want the page to continue to load anyway. ... $db = mysql_select_db('mobile', $conn); mysql_query("INSERT INTO redirects SET ua_string = '$ua_string'") or die('Error #10'); mysql_close($conn); ...

  • php validate integer [updated]

    - by George Garchagudashvili
    Read B A: I'll give quick example: $a = "\n \t 34 3"; // string(9) $aint = intval($a); // int(34) var_dump($a == $aint); result: bool(true) call me noob but can you tell me why/how does these variables do pass equalization test? What I want to achieve is to check if '1989' equals 1989 would be true, but not any other case. ex: '1989 ' should not pass the test. Also I don't want to use regex. B: I need to validate if variable is integer, I've tried all the available built-in functions or helpful tips, but the only best solution would be regex which I don't want to use this time. also filter_var is not best because it also filters data, but I want to only validate it. 123 -123 '123' '-123' these inputs to be only true, false otherwise I've tried many different options: ctype_digit("-123"); // false - doesn't work is_int('123'); // false filter_var(' 123 ', FILTER_VALIDATE_INT) !== false; // true - doesn't work

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

  • Oracle Blob as img src in PHP page

    - by menkes
    I have a site that currently uses images on a file server. The images appear on a page where the user can drag and drop each as is needed. This is done with jQuery and the images are enclosed in a list. Each image is pretty standard: <img src='//network_path/image.png' height='80px'> Now however I need to reference images stored as a BLOB in an Oracle database (no choice on this, so not a merit discussion). I have no problem retrieving the BLOB and displaying on it's own using: $sql = "SELECT image FROM images WHERE image_id = 123"; $stid = oci_parse($conn, $sql); oci_execute($stid); $row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS); $img = $row['IMAGE']->load(); header("Content-type: image/jpeg"); print $img; But I need to [efficiently] get that image as the src attribute of the img tag. I tried imagecreatefromstring() but that just returns the image in the browser, ignoring the other html. I looked at data uri, but the IE8 size limit rules that out. So now I am kind of stuck. My searches keep coming up with using a src attribute that loads another page that contains the image. But I need the image itself to actually show on the page. (Note: I say image, meaning at least one image but as many as eight on a page). Any help would be greatly appreciated.

  • Send mass emails php (probably a shell question?)

    - by Rob
    I've got 80,000 users on my site and i've recently turned away from the forum script i've been using and built something very simple myself that works just as well (the forum script was too bloated and resource intensive for my simple site) The only thing i've lost is the ability to mass email all my members. So i'm looking to come up with a script to do it myself. After looking around (including questions on here) I decided using Swift Mailer would be a good idea. However i've been through all the documentation and can't see how to send say "100 at a time" and i'm not sure how to go about it. To put it simply. I have an admin panel with a form with two inputs "subject" and "message". When I click submit what is the safest way for me to send 80,000 emails without crashing my server or being marked as spam? I'm on quite a beefy dedicated server so don't have the problems associated with shared servers. Thanks in advance for any advice!

  • Unable to change two things about a single row in mysql with php

    - by user1624005
    Here's the code: $id = intval($_POST['id']); $score = "'" . $_POST['score'] . "'"; $shares = "'" . $_POST['shares'] . "'"; $conn = new PDO('mysql:host=localhost;dbname=news', 'root', ''); $stmt = $conn->prepare("UPDATE news SET 'shares' = :shares, 'score' = :score WHERE id = :id"); $stmt -> execute(array( 'shares' => $shares, 'score' => $score, 'id' => $id )); And it doesn't work. I am unsure as to how I would see the error that I assume mysql is giving somewhere, and I've tried everything I could think of. Using double quotes and adding the variables into the statement right away. Adding single quotes to shares and score. How am I supposed to be doing this?

  • PHP DateTime accept multiple formats?

    - by John Smith
    I'm trying to construct a DateTime object with multiple accepted formats. According to the DateTime::createFromFormat docs, the first parameter (format) must be a string. I was wondering if there was a way to createFromFormats. In my case, I want the year for my format to be optional: DateTime::createFromFormat('Y-m-d', $date); DateTime::createFromFormat('m-d', $date); so that a user can input just 'm-d' and the year would be assumed 2013. If I wanted multiple accepted formats, would I have to call createFromFormat each time? Shortest thing for my scenario is: DateTime::createFromFormat('m-d', $date) ?: DateTime::createFromFormat('Y-m-d', $date);

  • What does the & sign mean in PHP?

    - by jeffkee
    I was trying to find this answer on Google but I guess the symbol & works as some operator, or is just not generally a searchable term for any reason.. anyhow. I saw this code snippet while learning how to create wordpress plugins, so I just need to know what the & means when it precedes a variable that holds a class object. //Actions and Filters if (isset($dl_pluginSeries)) { //Actions add_action('wp_head', array(&$dl_pluginSeries, 'addHeaderCode'), 1); //Filters add_filter('the_content', array(&$dl_pluginSeries, 'addContent')); }
