[RESOLVED] validate number

[nikko50]

Can someone help me with my little ole number validation fucntion. I'm trying to validate the user entered either a 5 digit number or a 6 digit number or a number formatted like such "123456-123456"" which is 6 numbers on each side of the "-".
I wrote the below function but it is evaluating true for some reason. Please feel free to rewrite the function if you have a better more shorter way of validating .

$x = "111111-99";

function validateCharge($charge)
{
 if ( preg_match ('/^[0-9]{5}$/', $charge) 
      || preg_match ('/^[0-9]{6}$/', $charge) 
      || preg_match ('/^[0-9]{6}((-| )[0-9]{6})?$/', $charge) ) {

return true;

} 

}




echo validateCharge($x);

function validateCharge($charge)
{
   return preg_match('/^(\d{5}|\d{6}([ -]\d{6})?)$/', $charge);
}

NogDog came up with a nice function that I currently use to validate numbers users are entering either a 5 digit, 6 digit or 12 digit number with 6 numbers on each side of the "-". We'll I forgot one thing to also validate and that is I don't want users to enter "00000" or "000000" or "000000-000000". How can a adjust the preg_match function to also validate that?

function validateCharge($charge)
{
   return preg_match('/^(\d{5}|\d{6}([ -]\d{6})?)$/', $charge);
}
