Description:
------------
Obs:This bug hape in PHP 4.4.x and 5.2.x
I have a string with 17bytes, 
sample:
<code>
 $var1 = '99990000000650719';
 $var2 = '99990000000650718';
</code>
if I compare these strings with:
<code>
if ( $var1 == $var2) echo "Equal"
else echo 'Not Equal'
</code>

it will print Equal, but this is incorrect.

The solution to correct do this, is using '===': $var1 === $var2

But this behavior is wrong.
I beliave that when php engine compare with '==' it cast variables to integer, and 17th byte is ignored!
