How to overwrite a PHP session variable

Question

Is this possible?

if ($_SESSION['variable'] = 'one' {
    $_SESSION['variable'] = 'car';
}

It doesn't seem to be working. Is this enough information?

Yes it is possible. Make sure variable is one though and remember to use session_start(); at the beginning of the file. Also, its: "if ($_SESSION['variable'] == 'one'){}" — Rijndael, May 22 '13 at 14:09
I didn't put the syntax in correctly here, I don't think it's the problem, this is my code `if ($_SESSION['variable'] == 'one') { $_SESSION['variable'] = 'car'; }` this should work, right? And I am using `session_start();` — Ghost Echo, May 22 '13 at 14:19
no! i'll look into it more! unless someone knows a stipulation which would prevent it from being over-written... — Ghost Echo, May 22 '13 at 15:08

Yes you can overwrite variables, but your codes syntax is wrong, try:

if ($_SESSION['variable'] == 'one') {
    $_SESSION['variable'] = 'car';
}

there is a syntax error and also in if clause your are not checking you are assigning the value

session_start();
if ($_SESSION['variable'] == 'one') {
$_SESSION['variable'] = 'car';
}

The reason it isn't working is due to your syntax errors.

Here's an example that might help you understand what's going on...

$_SESSION['variable'] = 'one';
// use == for comparison... = for variable assignment
if($_SESSION['variable'] == 'one'){
    // reassign
    $_SESSION['variable'] = 'car';
}

var_dump($_SESSION);

// array(1) { ["variable"]=> string(3) "car" }

There is a syntax error or probably a typo in your code Try this

if ($_SESSION['variable'] == 'one') {
    $_SESSION['variable'] = 'car';
}
