php preg_replace and perl regex matching

aolong · 06-02-2009, 09:33 AM

I'm having trouble with this one...

I need to replace everything from beginning of string up to the first occurrence of "= Gauge32: " OR "=STRING: " with "".

$output = shell_exec("./script.sh $propertyIP");
$pattern = 'the expression I can't seem to write';
$replace = '';

echo "<pre>" . preg_replace($pattern,$replace,$output) . "</pre>";

clues?

strange pattern ;-) Try this (untested):

Code:

$pattern = '.*(= Gauge32: )|(=STRING: )';
