Find text on an external html site

Jun 21st, 2005

Hi all,

Would anyone know how to search an external html file for a work or phrase ?

I was thinking something like -

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
<?php
$fp = fopen('http://www.google.ca', 'r');
 
if (preg_match('/Google.ca/', print fgets($fp))) {
	echo "match";
} else { 
	echo "no match";
}
?>
<?php
$fp = fopen('http://www.google.ca', 'r');

if (preg_match('/Google.ca/', print fgets($fp))) {
	echo "match";
} else { 
	echo "no match";
}
?>

Unfortunently, that doesn't work, but you get the jist of what I'm attempting.

Any ideas, suggestions, code would be greatfully appreciated,

Thanks,
Smoonie

I think what you're describing is called "screen scraping". There's an article on my site specifically about PHP screen scraping: http://www.tgreer.com/class_http_php.html

Of course, support DaniWeb. If you'd like to discuss that article, you can do so in this thread. The article author is also a DaniWeb member.

I'm the author of those articles and the class. It is posted here on Daniweb, but the article version at www.tgreer.com provides a lot more in-depth explanation of usage.

sm00nie, check out PHP's stripos() function. It is what you are looking for I believe.

Oops, stripos() is only available in PHP5, so check out strpos().
