help with passing variables though URL

[m4n1ac]

$error = $_GET['error'];
if ($error===1) {
echo"value is 1";
}

 

the URL i've entered is

 

http://localhost/index.php?error=1

 

why is this not working ?

[gristoi]

$error = $_GET['error'];
if ($error==1) {
echo"value is 1";
}

$_GET and $_POST values are stored as strings so you cannot perform a strict comparison using a string and an integer, it will always equate to false. You can either use the loose comparison operator as Gristoi has done above, or you can cast the value stored in $_GET['error'] as an integer and use the strict comparison as you have done.

 

As a side note, always check that $_GET and $_POST values isset before assigning their value to a variable.
