function swftools_array_merge in SWF Tools 6.3

Merges two multi-dimensional arrays.

This function is used by players that filter their settings to strip out blanks or defaults. For the admin page we need a full set of values to prevent errors. Since the arrays might be multi-dimensional we cannot use a regular array_merge(). The values in the first array will be over-written by values in the second, if they exist.

Parameters

array $array1: The first array to merge.

array $array2: The second array to merge.

Return value

array The result of the merge.

function swftools_array_merge($array1, $array2) {

  // Iterate over $array 2 (this is normally the smaller of the two)
  foreach ($array2 as $key => $value) {

    // If this key is present in $array1 then work out what to do
    if (isset($array1[$key])) {

      // If both keys hold arrays, combine them
