Question

Whilst developing a php class i have run into a rather interesting thing within php. If i was to create a array, some single keys and some with arrays within that key, it only echos numbers rather than the arrays key. Why is that and how do i fix it?

<?php

    $example = array('name' => array('required' => true), 'email');

    foreach($example as $field => $value) {
        echo $field;
    }

?>

This returns name0 rather than nameemail

Answer 1

you probably want this ::

<?php

    $example = array('name' => array('required' => true), 'email');

    foreach($example as $field => $value) {
        if(is_array($value)){
          echo $field;
        }else{
          echo $value;
        }
    }

?>
