String "info" is converted to integer, which is 0...

a)
if("info" == "0")

b)
if("info" === 0)

c)
if("info" == (string)0)


Or use strcmp()

Cya...

You probably mis-typed something:

[bogdan@myserver ~]$ php
<?
if ("info" == 0) echo "is 0\n"; else echo "not 0\n";
?>
Content-type: text/html
X-Powered-By: PHP/4.3.11

is 0

Cheers,
Bogdan
