help with simple regex function

[gammaman]

Why does thid function always evaluate to true? Based on what is being passed to the function, false should be returned.

 

<?php

  function test($var)
  {

    $pattern='^[A-Z][0-5]{3}$';

    $x=ereg($pattern,$var);

  }

  $value="1323";

  test($value);

  if($value==true){
     echo "value is true";
  }else{
     echo "false";
  }
?>

First, your function isn't returning anything. Second, you are testing the value of $value, not the return value. Your code should look like:

<?php
  function test($var)
  {
    $pattern='^[A-Z][0-5]{3}$';
    return ereg($pattern,$var);
  }

  $value="1323";
  $result = test($value);
  if($result){ //The == true is not needed
     echo "value is true";
  }else{
     echo "false";
  }
?>
