I'm trying to insert THE PHP CODE between the <div id="container"> THE PHP CODE HERE </div> . I'm using the http://simplehtmldom.sourceforge.net/ in this Php Html Parser.
I've got this so far, how to find a div having an id called container:
// Find all which attribute id=foo
$ret = $html->find('div[id=foo]');
Then after finding the foo, what's next?
$html->find('div[id=foo]')->innertext = 'bar';
Should do the job but you might be better off modifying the DOM with JS?
Why not modify the source Wordpress template instead of trying to hack in the text later? That PHP snippet could potentially produce a huge chunk of text, and you can't insert it verbatim into the DOM - you can only insert its output (which you'd have to capture with ob_start()/ob_get_clean() anywyas).

On a PHP+MySQL project, there's a string of text coming from a MySQL table that contains HTML tags but those tags never get rendered by Google Chrome or any browser I tried yet:
You can see that the HTML (p, strong) aren't getting interpreted by the browser.
So the result is:
EDIT: HTML/PHP
<div class="winery_description">
<?php echo $this->winery['description']; ?>
</div>
$this->winery being the array result of the SQL Select.
EDIT 2: I'm the dumbest man in the world, the source contains entities. So the new question is: How do I force entities to be interpreted?
Real source:
Any suggestions? Thanks!
You are probably using innerText or textContent to set the content of your div, which just replace the child nodes of the div with a single text node.
Use innerHTML instead, to have the browser parse the HTML and create the appropriate DOM nodes.
The answer provided by #Paulpro is correct.
Also note that if you are using jQuery, be sure to use the .html() method instead of .text() method:
$('#your_element').html('<h1>This works!</h1>');
$('#another_element').text('<h2>Wrong; you will see the <h2> in the output');
I dont know what to research or where to start here.
What im trying to do is use PHP to read an HTML Page and pull out the raw text contained inside a div
the div is this
<div class="thingy">
test
</div>
When the php is executed, I want it to echo
Test
Is there an easy snippet for this, or can someone post a small script?
Edit: the html page with the Div is on another webpage.
What you're looking to do is parse HTML. Use the DOM module that comes with PHP to do this: http://php.net/manual/en/book.dom.php
You do NOT want to try to do this with regular expressions.
If you want to remove ALL the HTML tags from a document, use the PHP strip_tags() function: http://us3.php.net/strip_tags
While this could possibly be done using regex, I would recommend using a DOM parser. My reccommendation goes to SimpleHTML Dom Parser. Using it, here's how you would do what you want
$string = "<div class=\"thingy\">test</div>";
$html = str_get_html($string); // create the DOM object
$div = $html->find('div[class=thingy]', 0); // find the first div with a class of 'thingy'
echo $div->plaintext(); // echo the text contents
If you want to parse your html you can use it like
<?php
$str = '<div class="thingy">test</div>';
echo strip_tags($str);//OUTPUT : test
?>
As your html is on other webpage, start output buffering include that file in your main php script, do all manipulation on it to get the content.
Let's say i have this block of code,
<div id="id1">
This is some text
<div class="class1"><p>lala</p> Some markup</div>
</div>
What I would want is only the text "This is some text" without the child element's .class1 contents. I can do it in jquery using $('#id1').contents().eq(0).text(), how can i do this in phpQuery?
Thanks.
my bad, i was doing
pq('#id1.contents().eq(0).text()')
instead of
pq('#id1')->contents()->eq(0)->text()
If compatibility is what you are after, and you want to traverse/manipulate elements as DOM objects, then perhaps the PHP DOM XML library is what you are after: http://www.php.net/manual/en/book.domxml.php
Your code would look something like this:
$xml = xmldoc('<div id="id1">This is some text<div class="class1"><p>lala</p> Some markup</div></div>');
$node = $xml->get_element_by_id("id1");
$content = $node->get_content();
I'm sorry, I don't have time to run a test of this right now, but hopefully it sets you in the right direction, and forms the basis for a decent revision... There is a good list of DOM traversal functions in the PHP documentation though :)

What I've been trying to do recently is to extract listing information from a given html file,
For example, I have an html page that has a list of many companys, with their phone number, address, etc'
Each company is in it's own table, every table started like that: <table border="0">
I tried to use PHP to get all of the information, and use it later, like put it in a txt file, or just import into a database.
I assume that the way to achieve my goal is by using regex, which is one of the things that I really have problems with in php,
I would appreciate if you guys could help me here.
(I only need to know what to look for, or atleast something that could help me a little, not a complete code or anything like that)
Thanks in advance!!
I recommend taking a look at the PHP DOMDocument and parsing the file using an actual HTML parser, not regex.
There are some very straight-forward ways of getting tables, such as the GetElementsByTagName method.
<?php
$htmlCode = /* html code here */
// create a new HTML parser
// http://php.net/manual/en/class.domdocument.php
$dom = new DOMDocument();
// Load the HTML in to the parser
// http://www.php.net/manual/en/domdocument.loadhtml.php
$dom->LoadHTML($htmlCode);
// Locate all the tables within the document
// http://www.php.net/manual/en/domdocument.getelementsbytagname.php
$tables = $dom->GetElementsByTagName('table');
// iterate over all the tables
$t = 0;
while ($table = $tables->item($t++))
{
// you can now work with $table and find children within, check for
// specific classes applied--look for anything that would flag this
// as the type of table you'd like to parse and work with--then begin
// grabbing information from within it and treating it as a DOMElement
// http://www.php.net/manual/en/class.domelement.php
}
If You're familiar with jQuery (and even if You're not as it's command are simple enough) I recommend this PHP counterpart: http://code.google.com/p/phpquery/
If your HTML is valid XML, as in XHTML, then you could parse it using SimpleXML
I'm trying to fetch data from a div (based on his id), using PHP's PCRE. The goal is to fetch div's contents based on his id, and using recursivity / depth to get everything inside it. The main problem here is to get other divs inside the "main div", because regex would stop once it gets the next </div> it finds after the initial <div id="test">.
I've tryed so many different approaches to the subject, and none of it worked. The best solution, in my oppinion, is to use the R parameter (Recursion), but never got it to work properly.
Any Ideais?
Thanks in advance :D
You'd be much better off using some form of DOM parser - regex really isn't suited to this problem. If all you want is basic HTML dom parsing, something like simplehtmldom would be right up your alley. It's trivial to install (just include a single PHP file) and trivial to use (2-3 lines will do what you need).
include('simple-html-dom.php');
$dom = str_get_html($bunchofhtmlcode);
$testdiv = $dom->find('div#test',0); // 0 for the first occurrence
$testdiv_contents = $testdiv->innertext;
