How do I validate multiple patterns?

Question

I have a single form element that sends its value to a PHP script. This value needs to be validated and it there are 5 different sets that it can be grouped to,

x stands for digits 0-9

Set 1: ABxxTXxx

Set 2: ABxxTXAxxx

Set 3: ABCxxx

Set 4: Axxx

Set 5: xxx

Can this be done? Is there any library I could use?

You can use this code :

function validate($value){



    if(preg_match("/AB[\\w]{2}TX[\\w]{2}/", $value, $matches))
    {
        return 1;
    }
    elseif(preg_match("/AB[\\w]{2}TXA[\\w]{3}/", $value, $matches))
    {
        return 2;
    }
    elseif(preg_match("/ABC[\\w]{3}/", $value, $matches))
    {
        return 3;
    }
    elseif(preg_match("/A[\\w]{3}/", $value, $matches))
    {
        return 4;
    }
    elseif(preg_match("/[\\w]{3}/", $value, $matches))
    {
        return 5;
    }
    else
    {
        return 6;
    }

}


$str = "ABxxTXxx";
var_dump(validate($str));
