in_array problem

[Good2CU]

This code doesn't seem to work, so I'm hoping someone can point out something wrong with it:

[code=php]
foreach($stringArray as $value) {
$exceptionArray = array('test'); //create list of exceptions that should be upper case
if (in_array($value, $exceptionArray)) strtoupper($value);
}

[/code]

Assuming $value = 'test', is there anything wrong with this? There is only one statement if this is true, and I tried brackets anyway and that didn't seem to make the difference. I'm trying to make test == TEST.

Thanks

The first problem is that you are not assigning the return value of strtoupper() back to the array. A more minor problem is that creating $exceptionArray in the loop is inefficient. You might write something like this:

$exceptionArray = array('test'); //create list of exceptions that should be upper case
foreach ($stringArray as $key => $value) {
    if (in_array($value, $exceptionArray))
        $stringArray[$key] = strtoupper($value);
}
