Errors in php 5.0.4 Not in 4.3.10-16

[Han Koster]

I use the following statements:

$var = "";
$var = $_POST('varname');

In php 4, when 'varname' was not defined, $var remained an empty string;
In php 5, I suddenly get errors.

I solved these by including the function array_key_exist to check the
occurence of 'varname'
Is this the prefered way or is ther a better solution?

Thanx,
Han koster

Han,

You might have had display errors turned off in PHP 4.

It's always good to see if something exists before trying to use it. I
use isset($_POST['varname']), but I'm sure array_key_exist will work
just fine.

My code looks something like:

$var = isset($_POST['varname']) ? $_POST['varname'] : 'default_value';

That way I can set a default - even if it is null.

Did you get an error or a notice?
It is neccessary in PHP 5 to declare variables before use them.

Are you sure about that?
