Function for removing repeated values of an array

Php can also be understood as a function for removing repeated values of arrays.

/*** Difference between array weighting * and the array_unique function: it requires that val be a string, this can be an array/object ** @ param $ arr array to be realigned * @ param $ reserveKey whether to retain the original Key * @ return array */function m_ArrayUnique ($ arr, $ reserveKey = false) {if (is_array ($ arr )&&! Empty ($ arr) {foreach ($ arr as $ key => $ value) {$ tmpArr [$ key] = serialize ($ value ). '';} $ tmpArr = array_unique ($ tmpArr); $ arr = array (); foreach ($ tmpArr as $ key => $ value) {if ($ reserveKey) {$ arr [$ key] = unserialize ($ value);} else {$ arr [] = unserialize ($ value) ;}} return $ arr ;}
