strange! have u got such problem??

littleknife

i don't know if it is a bug:
when execute this:
<?php
$test = 1;
if ($test == "h")
echo "ok";
else
echo "no";
?>

output is : no

but when execute this:
<?php
$test = 0;
if ($test == "h")
echo "ok";
else
echo "no";
?>
output is : ok

why?

nomad9

strange but ...

i test it and if u use

$test = "0";

instead of

$test = 0;

it work ... maybe 0 is like false and 1 like true ???

You are correct nomad9.

0 == FALSE
1 or any number == TRUE

So the if() was comparing
TRUE == "h"
which means TRUE==TRUE

The other case

FALSE == TRUE

So it's no bug just bad logic.

If you want to put a string into a variable always use quotes.

The PHP people have developed the === operator to get around this problem. It checks that the values are equal and of the same type.

$test = 0;
if ($test === "h")
echo "ok";
else
echo "no";
