[RESOLVED] match a value

[zzz]

I have a string of values that was created via implode and looks like

212,34,55,65,143

I need to run a loop and compare if a given value found in this string. Shall I use preg_match

if (preg_match($myValue, $myStr) {

[rsmith]

if(in_array($submittedValue, $arrayName){
     echo "Match Found!";
}

[zzz]

But it's not an array. Shall I declare it as an array? It's kinda like this:

$array = array(234, '333', '44'); // this is array
$comma_separated = implode(",", $array); // this is not an array

So how do I find if a given value is in $comma_separated string?

Well, if the original array still exists, just use the in_array() function on that array instead of the imploded string. But if all you have is the string for some reason, then either explode() it back into an array to use in_array(), or else you could use preg_match() something like:

if(preg_match('/\b' . preg_quote($value) . '\b/', $comma_separated))
{
   // it's in there
}

I had original array, but kept loosing it. Finally I just added it to session and it all works now.
