I wrote a very simple function that allows you to search a folder for a file name with a regular
expression. It can handle both PREG and EREG regexps and can accept different case sensitivities for
EREG regexps.
function regExpFile($regExp, $dir, $regType='P', $case='') {
# Two parameters accepted by $regType are E for ereg* functions
# and P for preg* functions
$func = ( $regType == 'P' ) ? 'preg_match' : 'ereg' . $case;
# Note, technically anything other than P will use ereg* functions;
# however, you can specify whether to use ereg or eregi by
# declaring $case as "i" to use eregi rather than ereg
$open = opendir($dir);
while( ($file = readdir($open)) !== false ) {
if ( $func($regExp, $file) ) {
return true;
}
} // End while
return false;
} // End function
Basically if you supply anything but "P" for $regType it will assume you're using
EREG regexps. The case should only be blank or "i".
