[RESOLVED] PHP, get html source.

I'm working on a project that needs to watch another website for activity. I can go thru a logon, query and signon at regular intervals. But it occurs to me that you can just see if something new has happened by viewing the site.

So I was wondering if there is some PHP command to capture HTML source from an external website and then I'll search the html source for a number of images (or any related events, updates etc).

So from a PHP script I'd like to point it at an unrelated website and scrape the HTML source for a particular pages.

a little sumtum like....
$string get_html_source ('www.foo.bar/page001/bogus-news.html');

ideas?

<?php
// Get a file into an array.  In this example we'll go through HTTP to get 
// the HTML source of a URL.
$lines = file('http://www.example.com/');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
   echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

// Another example, let's get a web page into a string.  See also file_get_contents().
$html = implode('', file('http://www.example.com/'));

Big thanks for the great code. It worked great and I was looking for images and the website used a very good naming standard which allowed me to see the updates.

However it is a bit of CPU hog. Seems to rival that of the logon, poke around, logoff plan.

But I love having that option in my code bank.

Thanks!
