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?

  • 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!! =)

  • 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.

  • 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.

  • 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!

  • PHP and storing stats

    - by John
    Using PHP5 and the latest version of MySQL I want to be able to track impressions and clicks for business listings. My question is if I did this myself what would be the best method in storing it so I can run reports? Before I just had a table that had the listing id, user ip address and if it was a click or impression as well as the date it was tracked. However the database itself is approaching 2GB of data and its very slow, part of the problem is its a pretty simple script that includes impressions and clicks from anyone including search engines and basically anyone or anything that accesses the listing page. Is there an api or file out there that has an update to date list that can detect if the person viewing is a actually person and not a spider so I dont fill up the database with unneeded stats? Just looking for suggestions, do I just have a raw database that gets just the hits then a cron job at night tally up for the day for each listing for each ip and store the cumulative stats in a different table? Also what type of database should it be? Innodb? MyISAM?

  • Echo a multidimensional array in PHP

    - by Jennifer
    I have a multidimensional array and I'm trying to find out how to simply "echo" the elements of the array. The depth of the array is not known, so it could be deeply nested. In the case of the array below, the right order to echo would be: This is a parent comment This is a child comment This is the 2nd child comment This is another parent comment This is the array I was talking about: Array ( [0] => Array ( [comment_id] => 1 [comment_content] => This is a parent comment [child] => Array ( [0] => Array ( [comment_id] => 3 [comment_content] => This is a child comment [child] => Array ( [0] => Array ( [comment_id] => 4 [comment_content] => This is the 2nd child comment [child] => Array ( ) ) ) ) ) ) [1] => Array ( [comment_id] => 2 [comment_content] => This is another parent comment [child] => Array ( ) ) )
