How to get the first item from an associative PHP array?

Question

If I had an array like:

$array[\'foo\'] = 400;
$array[\'bar\'] = \'xyz\';

And I wanted to get the first item out of that array without knowing

Answer 1

Test if the a variable is an array before getting the first element. When dynamically creating the array if it is set to null you get an error.

For Example:

if(is_array($array))
{
  reset($array);
  $first = key($array);
}
