what is more efficent than strpos?

[mw-dnb]

i'm currently using strpos to detect if a certain string appears in another string.

example:

<?
$MY_STRING= 'Find the text in the string';
$MY_FIND= 'text';

if (strpos($MY_STRING, $MY_FIND)!==false) {
//do something
} 

?>

I plan on checking the values against a database list of search words.

i need this to be done as fast as possible as the script takes up to 30 minutes to completly execute. (its used in a site archiving tool i'm working on)

any help or examples are greatly appreciated.

That's about as efficient as you're going to get. Are you sure that the bottleneck is the strpos() function and not something else...

More than likely it's your queries taking so long, and not these comparisons. You might see if you can move some of the logic directly into the database also to save on some queries.
