Search for string and then take string next to it.

Hi,

What I'm looking for is a way for php to retrieve a webpage, search for a
string in it, and next to that will be a date string in the format (e.g.)
03-Sep-04 22:37:40 BST, and then I'd like PHP to store that as a date/time
variable (preferably using unix timestamp)...

This possible?

Thanks,

Ben

Also, the timezone is irrelevant, I just need a way of identifying dd-mm-yy
hh:mm:ss as a php date/time stamp to perform time calculations on it...

Thanks!

I now need to search for a string and return the next X characters to
it....

I'm guessing I'd use libcurl or similar to retrieve the webpage, and them
do strpos to find the string, but how to get the characters next to it?

I'm looking at
between... sometihng like between
between ('string1', 'string after what i want',$retrievedpage);

then strtotime...
That the best way?

Thanks,
ben

<?php
function text_after($haystack, $needle, $size) {
$pos = strpos($haystack, $needle);
if ($pos === false) return false;
return substr($haystack, $pos+strlen($needle), $size);
}

$text = 'one two three four five six seven';

$found = text_after('three', 5, $text);
if ($found === false) echo "Not found\n";
else echo 'Found: ', $found, "\n";
?>

Oops, this last line should have been

$found = text_after($text, 'three', 5);
