Note Submitter: talik at professionalscallywag dot com ---- A minor improvement to elkabong's array_deep_copy function to allow for easier inline use by using a return value rather than requiring the result array to be passed into the function. <?php /* Make a complete deep copy of an array replacing references with deep copies until a certain depth is reached ($maxdepth) whereupon references are copied as-is. never call this function with $depth variable specified. */ function array_copy (&$array, &$copy = false, $maxdepth=50, $depth=0) { if($depth > $maxdepth) { $copy = $array; return; } if(!is_array($copy)) { $returnCopy = true; $copy = array(); } foreach($array as $k => &$v) { if(is_array($v)) { array_copy($v,$copy[$k],$maxdepth,++$depth); } else { $copy[$k] = $v; } } if($returnCopy) return $copy; } //call it like: $newArray = array_copy($oldArray); //or $newArray = array_copy($oldArray, false, $maxDepth); //or $newArray = array(); array_copy($oldArray, $newArray, $maxDepth); ?>
