PHP and Arrays

[berbbrown]

Hi All

	foreach ($consumers as $key => $consumer) {
		if ($consumer ['transstatus'] == 'OK') {
			$consumers [$key] ['transstatus']= "Payment Successful";
		}
	}

I am trying to update the content of an element in my array above.

The consumers array contains the data is created by an sqlquery.

It doesn't seem to update the for some reason.

Can anyone help please?

The issue is that foreach works on a copy of the array not the actual array itself. So you're updating a 'copy' of the array, that is effectively removed from memory once the foreach loop has completed. You can either reference the array, copy the array to a temp variable name and refer back to it in your foreach loop, or use a for loop (depending on what you're using as keys).

Good luck. 🙂

Actually, the code you're using should work; that is, it should be altering the original array. If it doesn't "seem" to update, something else is wrong.

As Eric said, (with PHP5) you can also reference the array:

foreach ($consumers as &$consumer) {
    if ($consumer['transstatus'] == 'OK') {
        $consumer['transstatus'] = 'Payment Successful';
    }
}
