How to find the position of end of a string?

Hi, say i have a string that looks like:

//Comment1 //
Hey look
//Comment2 //
Now look

How do I get the position number of the end of "//Comment1 //"
BTW the length of the string is variable, so I can't count from the start.

 

<?
$string = '//Comment1 //
Hey look
//Comment2 //
Now look';

function strpostend( $haystack, $needle, $offset = null )
{
	return strpos( $haystack, $needle, $offset ) + strlen( $needle );
}

$test1 = 'Comment1 //';
printf('%s ends at offset %d<br />', $test1, strpostend( $string, $test1 ) );
printf('The rest of the string is<br /><pre>%s</pre>', substr( $string, strpostend( $string, $test1 ) ) );

PHP:

like that .....

 

ok with a good bit of modification it works perfectly, thanks

 

what did you have to modify ??

I musta misunderstood the question, as I understand it returns the position of the end of the string you pass to it ......

 

Yeah I posted example code, that wasn't exactly how it was in my real code *oops* so it was my fault.
