Re: Assign values in foreach-loop

[<tg-php@xxxxxxxxxxxxxxxxxxxxxx>]

Yeah, you can assign values, but you have to keep track of keys, so you'll want to use the => operator for foreach (pardon my reformatted, I feel naked without my braces):

foreach ($_SESSION['arr1'] as $key1 => $arr1)  {
    foreach ($_SESSION['arr2'] as $key2 => $arr2) {
        if ($arr1['id'] == $arr2['id']) {
            # $arr1['selected'] = true;
            $_SESSION['arr1'][$key1]['selected'] = true;
        }
    }
}

Is that what you were trying to do?

Hello to all,

is it possible to assign values to the array for which I do the 
foreach-loop?

foreach ($_SESSION['arr1'] as $arr1) 
    foreach ($_SESSION['arr2'] as $arr2) 
        if ($arr1['id'] == $arr2['id']) 
            $arr1['selected'] = true;
        
       


I think $arr1 is only a temp-var, so the assignment won't reflect on 
$_SESSION['arr1'] . Is that right?
Surely I can do it with a for-loop, but those arrays are a bit complex 
and a foreach would be much easier to read.

Thanks in advance for your answers
Sabine
