Preg match question - only one result is succesful

PHP
1

I am using the following code to look for semi-colons and commas in a $subject. While each works individually, if I make a string (like “,;”)that combines semi-colon AND a comma, only the comma function works. (It reads “comma found”.)


if (preg_match('/^;$/', $subject))
{
	echo "semi colon found";
}

if (preg_match('/^,$/', $subject))
{
	echo "comma found";
}

Any ideas on identifying the problem here?

$subject = ",;";

if (preg_match('/;/', $subject))
{
    echo "semi colon found";
}

if (preg_match('/,/', $subject))
{
    echo "comma found";
}

semi colon found comma found

hope it helps :wink:

That did the trick - thanks!

You (s|c)ould implement a character class instead.


<?php
if(preg_match('~[,;]~', 'subject'))
{
    echo 'comma or semi-colon found';
}

You could also use the strpos function.

$found = strpos($subject, ",") !== false || strpos($subject, ";") !== false;
