How do I use a variable template with preg_match?
I do not know if there is enough data to submit, but I have
preg_match ('/ SAMPLETEXT /', $ bcurl, $ cookie1);
and I was wondering if I can do this
preg_match ($ newfunction, $ bcurl, $ cookie1);
but when i do that i get this error: "Warning: preg_match () [function.preg-match]: separator must not be alphanumeric or backslash in".
How can I get it to check my new function and not only check for "SAMPLETEXT".
Try preg_match("/$newfunction/", $bcurl, $cookie1);
so that you provide the delimiters you require (using a delimiter that will not be in $ newfunction).
But note that the documentation says, “Don't use preg_match () if you only want to check if one line is contained in another line. Use strpos () or strstr () instead, as they will be faster.
preg_match('/'.$pattern.'/i', $subject)
i
: Allow capital letters or hyphens.
u can use a variable by placing it between []
$subject = "abcdef";
$ch = 'b';
$pattern = '/[$ch]/';
preg_match($pattern, $subject, $matches);
//print_r($matches);
if ($matches)
{
echo $subject;
}
