A simple trick that can help you to guess what diff/intersect or sort function does by name.
Example: array_diff_assoc, array_intersect_assoc.
Example: array_diff_key, array_intersect_key.
Example: array_diff, array_intersect.
Example: array_udiff_uassoc, array_uintersect_assoc.
This also works with array sort functions:
Example: arsort, asort.
Example: uksort, ksort.
Example: rsort, krsort.
Example: usort, uasort.
?>
Return:
Array ( [ 0 ] => Cero [ 1 ] => Uno [ 2 ] => Dos [ 3 ] => Cuatro [ 4 ] => Cinco [ 5 ] => Tres [ 6 ] => Seis [ 7 ] => Siete [ 8 ] => Ocho [ 9 ] => Nueve [ 10 ] => Diez )

Updated code of ‘indioeuropeo’ with option to input string-based keys.
Here is a function to find out the maximum depth of a multidimensional array.
// return depth of given array
// if Array is a string ArrayDepth() will return 0
// usage: int ArrayDepth(array Array)
Short function for making a recursive array copy while cloning objects on the way.
If you need to flattern two-dismensional array with single values assoc subarrays, you could use this function:

i think better way for this is using JSON, if you have such module in your PHP. See json.org.
to convert JS array to JSON string: arr.toJSONString();
to convert JSON string to PHP array: json_decode($jsonString);
You can also stringify objects, numbers, etc.
Function to pretty print arrays and objects. Detects object recursion and allows setting a maximum depth. Based on arraytostring and u_print_r from the print_r function notes. Should be called like so:
I was looking for an array aggregation function here and ended up writing this one.
Note: This implementation assumes that none of the fields you’re aggregating on contain The ‘@’ symbol.
While PHP has well over three-score array functions, array_rotate is strangely missing as of PHP 5.3. Searching online offered several solutions, but the ones I found have defects such as inefficiently looping through the array or ignoring keys.
