array_diff_uassoc() – Computes the difference of arrays with additional index check which is performed by a user supplied callback function
array_udiff() – Computes the difference of arrays by using a callback function for data comparison
array_udiff_assoc() – Computes the difference of arrays with additional index check. The data is compared by using a callback function
