I can't find the comma in a string

[robertaccettura]

Ok, this is a dumb question (hence I ask)... still learning PHP command by painful command...

How do I check to see if a comma is in a string? I tried this:

preg_match (",/i", $ticket, $result);

But I take it, that's not correct syntax....

So what is?

[mahers]

$s = "This is , a string,,!";
if(preg_match("/,/",$s))
    echo "commas exist";
else
    echo "no commas!";

Plenty of ways to do it, but. . . knowing that strstr() returns true or false. . .

$string = "4,00ag";

if(strstr($string, ",")) {
   echo "comma found";
} else {
   echo "no comma found";
}
