If I have the html file:
<!doctype html>
<html>
<head></head>
<body>
<!-- Begin -->
Important Information
<!-- End -->
</body>
</head>
</html>
How can I use PHP to get the string "Important Information" from the file?

It isn't (mostly) the parsing i'm worried about, more getting the code in the first placeJJJollyjim– JJJollyjim2011-02-16 04:05:10 +00:00Commented Feb 16, 2011 at 4:05

Title is highly misleading, you're not "getting the HTML source code." You're just getting the text.BoltClock– BoltClock2011-02-16 04:08:11 +00:00Commented Feb 16, 2011 at 4:08

If you already have the parsing sorted, just use file_get_contents(). You can pass it a URL and it will return the content found at the URL, in this case, the html. Or if you have the file locally, you pass it the file path.

In this simple example you can open the file and do fgets() until you find a line with <!-- Begin --> and saving the lines until you find <!-- End -->.
If your HTML is in a variable you can just do:
<?php
$begin = strpos($var, '<!-- Begin -->') + strlen('<!-- Begin -->'); // Can hardcode this with 14 (the length of your 'needle'
$end = strpos($var, '<!-- End -->');
$text = substr($var, $begin, ($end - $begin));
echo $text;
?>
You can see the output here.

How can I use fgets with a $var?

Don't forget the whitespace before
<!-- Begin -->

Is this
$var a string with the HTML content?You can fetch "HTML" by this
//file_get_html function from third party library
// Create DOM from URL or file
$html = file_get_html('http://www.example.com/');
and any operation on DOM then read following docs: http://de.php.net/manual/en/book.dom.php

There is no
file_get_html in DOM or in PHP.Gordon
@Manish simplehtmldom is a third party library and not a native PHP extension. You linked to
DOM in your answer.
