Check Number

 / Published in: PHP
 

I want to get only number from user it does not start with zero. I think it's not perfect but works for me.

Expand | Embed | Plain Text 
  1. function check_number($num) {	
  2.  
  3. 		if ( $num[0] == 0 ) { // don't allow 0 start.
  4. 			return false;
  5. 		}
  6. 		if (preg_match("/^[0-9]+$/", $num)) {
  7. 			return true;
  8. 		} else {
  9. 			return false;
  10. 		}
  11.  
  12. 	}

function checknumber($num) { if (isnumber($num) & $num != 0) { return true; } else { return false; } }
