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
