PHP version:      5.2.13
Package:          *General Issues

Bug description:invalid result

Description:
------------
When I want test the value(int 0) is or is not match with a string(string
"text"), it return true! By right it should return false. Then I try on
other value, it also return wrong result!

Test script:
---------------
<?php

  $question = true;
  if ("text" == $question) echo "text == $question => true<br />";
  else echo "text == $question => false<br />";

  $question = 0;
  if ("text" == $question) echo "text == $question => true<br />";
  else echo "text == $question => false<br />";

  $question = 1;
  if ("text" == $question) echo "text == $question => true<br />";
  else echo "text == $question => false<br />";

  $question = false;
  if ("text" == $question) echo "text == $question => true<br />";
  else echo "text == $question => false<br />";
  
?>

Expected result:
----------------
text == 1 => false
text == 0 => false
text == 1 => false
text == => false


Actual result:
--------------
text == 1 => true
text == 0 => true
text == 1 => false
text == => false
