This code doesn’t work > <b>Fatal error</b>: Cannot use [] for reading i

  <select style=" width:200px" class="mydds"  name="myformdata[user][]">

this is what is sent.

myformdata[user][]  1
myformdata[user][]  2
myformdata[user][]  3

  foreach($form['user'][] as $val){
            echo ($val);
    }

what is the problem ?

Answer 1

It’s a syntax error. The correct syntax is:

foreach($form['user'] as $val)

The [] syntax is used for appending data to an array. For example:

$form['user'][] = 'test';

The above will add a new string to the $form['user'] array with the value of test.
