You miss something :) Strings will be converted to a number first, which is not possible. The result
of this conversion is 0, and (0 == 0) => TRUE.

When strings are compared to 0, they always return TRUE.

<?php
$test = 'somestring';
if( $test == 'somestring')
echo "Match 1\n";
if( $test == 0 )
echo "Match 2\n";
if( $test == 1 )
echo "Match 3\n";
if( $test != 0 )
echo "Match 4\n";
if( $test != 'somestring' )
echo "Match 5\n";
if( $test != 1 )
echo "Match 6\n";
?>

Expected Output:
Match 1


Actual Ouput:
Match 1
Match 2
Match 6

Is there something I'm missing?
