• Using json_encode on objects in PHP

  - by Alan

  Hi, I'm trying to output lists of objects as json and would like to know if there's a way to make objects usable to json_encode? The code I've got looks something like $related = $user->getRelatedUsers(); echo json_encode($related); Right now, I'm just iterating through the array of users and individually exporting them into arrays for json_encode to turn into usable json for me. I've already tried making the objects iterable, but json_encode just seems to skip them anyway.

• php and XML range into array

  - by Mike

  The code below helps be to get the WHOLE XML and put it into an array. What I'm wondering is, what would be a good way to get the XML only from item 3 - 6 or any arbitrary range instead of the whole document. $mt_arr = array(); $d = new DOMDocument(); $d->load('http://news.google.com/?output=rss'); foreach ($d->getElementsByTagName('item') as $t) { $list = array ( 'title' => $t->getElementsByTagName('title')->item(0)->nodeValue); array_push($mt_arr, $list); } Thanks

• PHP - Problem using file_get_contents

  - by shyam

  I have a problem while using the file_get_contents function. I am using it to get a response from a different web server, but it's not returning anything (shown as empty string using var_dump). Also, the problem is only while calling this specific server, because I got result when I used Google's address; and it's working fine in my local machine. I've tried cUrl too - but same result.

• How can I use "PHP Simple HTML DOM Parser" to get the contents of an <h1></h1> tag?

  - by KeriLynn

  I'm new to PHP =) Right now I am using PHP includes for my site template. I have my header, containing all my <head></head> info. What I want to do is write a code that will take the contents of the <h1></h1> tag from the page, and echo it into the <title></title> tag in my header.php include. I got the PHP Simple HTML DOM Parser from here: http://simplehtmldom.sourceforge.net/, and I found a code (I forget where in all my googling) that goes like this: <?php $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $html = file_get_html('http://www.google.com/'); foreach($html->find('#content h1') as $element){ echo $element->plaintext;} ?> That I think is supposed to echo the h1 tag contents? Like I said, I'm new to PHP and I only know the basics, and I don't know really know any OOP (yet), so I'm sorry if I'm asking a dumb question. It looks like it's getting the current page, then putting the contents of the h1 tag into the variable $element, and then echoing it. But nothing happens when I put it into my page. Can anyone help me with what I'm doing wrong? Thank you for reading!! =)

• PHP: Accessing an object property with a variable.

  - by Peter

  Let's assume I have an array of object properties I'd like to access: $properties = array('foo', 'bar'); I'd like to loop through the object and access these properties dynamically (specifically, I'm trying to dynamically handle missing JSON elements based on an array of expected elements): foreach ($data as $item) { foreach ($properties as $property) { if (empty($item->{$property})) { // Do something } } } Each $item in $data should have the properties 'foo' and 'bar'. If empty(), I'll handle them. I'm trying to get the loop (in line 3) to access $item-{'foo'} and $item-{'bar'}, but it's not working. Any idea why? Thanks!

The data we have to work with is the whole pages HTML as a variable. The page & URL will be different for every time this function runs. Are there any libraries or classes that are particularly good at getting the main body of content, much like Instapaper that would be of any help?

• php read CSV with various amount of delimiters

  - by jreed121

  I've got a script that reads in from a CSV file and sometimes the CSV files it receives contains an uneven amount of delimiters/columns so the first row could have 30 columns, the 2nd could have 20, etc. I can think of a few solutions myself ie: Count the delimiters in the widest row, then append the proper amount to each row that is short to make them even. But I was wondering if anyone had a more elegant method of doing this.

• override __set in __construct() in php?

  - by user151841

  I have a class based on database values. I'm using __set to automatically sync database values with the class properties. Set checks an array of database fields that it is allowed to update in the database. The field 'id' isn't in the list, so __set will throw an exception if you try to do $objDbRow->id = 5;. However, there is one time when I do want to set the id property of the object, and that's on instantiation. So in __constuct, I have $this->id = $id (where $id is passed to __construct). However, __set seems to be intercepting the setting here, because an exception is being thrown on construction. What's the way to get around this? I suppose I also have a boolean flag, like $instantiated, that __set() would check before it does it's field whitelist checking. But that feels inelegant.
