Question

Consider the following array:

$array[23] = array(
  [0] => 'FOO'
  [1] => 'BAR'
  [2] => 'BAZ'
);

Whenever I want to work with the inner array, I do something like this:

foreach ($array as $key => $values) {
  foreach ($values as $value) {
    echo $value;
  }
}

The outer foreach-loop is there to split the $key and $value-pairs of $array. This works fine for arrays with many keys ([23], [24], …)but seems redundant if you know beforehand that $array only has one key (23 in this case). In a case as such, isn’t there a better way to split the key from the values? Something like

split($array into $key => $values)
foreach ($values as $value) {
  echo $value;
}

I hope I made myself clear.

Answer 1

reset returns the first element of you array and key returns its key:

$your_inner_arr = reset($array);
$your_key = key($array);
