substring/trim between delimeters

[jmurch]

Hi All,

 

Is there a PHP function that will trim the string and leve only the content between two delimiters?

 

ex:

 

whatever_the_function (delimiter, string, delimiter) so the the output is the sting with everthing before the first delimiter deleted and everything after the last delimiter deleted.

 

so that stringstringstringstringxxxxstringstringyyyystring would result in stringstring if the first delim were xxxx and the second were yyyy.

 

Thanks, Jeff

Nope, but you could make one using a combination of strpos and substr or maybe even ereg_replace.

You could create your own function that uses a series of "explode()" functions to get the result:

<?php
function get_string($delim1,$str,$delim2) 
{
     list($dmy,$tmp) = explode($delim1,$str,2);
     list($tmp,$dmy) = explode($delim2,$tmp,2);
     return ($tmp);
}
$string = 'stringstringstringstringxxxxstringstringyyyystring';
$newstring = get_string('xxxx',$string,'yyyy');
echo $newstring;
?>

Ken.

 

Thanks. Your solution is almost perfect. I should have explained it correctly in that I need to keep the delimeters as part of the final string.  The output needs to be:

 

xxxxstringstringyyyy

 

I'm using this to strip out the XML that is outside of the body open and body closed tags so I need to use the body tags as delimeters but keep them as part of the string as well. If this is not possible I guess I could always concatonate them back in after the function has run.

That would be a good idea.

Just change the function to:

<?php
function get_string($delim1,$str,$delim2) 
{
     list($dmy,$tmp) = explode($delim1,$str,2);
     list($tmp,$dmy) = explode($delim2,$tmp,2);
     return ($delim1 . $tmp . $delim2);
}
?>
