Difference sets and intersections in arrays of PHP array functions

Array_diff ($arr, $arr 2[...]) Returns an array that contains all the values in $ARR1 but not in any other parameter array, with the key name unchanged

Array_diff_uassoc ($arr, $arr 2, [...], ' cmp_function ') using a callback function to index the difference set in an array

Array_diff_assoc ($arr, $arr 2[...]) returns an array that $arr the difference between the other array and the key name index unchanged

Array_udiff ($arr, $arr 2 [...], ' cmp_function ') compare the data with the callback function to calculate the difference set of the array

Array_udiff_uassoc ($arr, $arr 2, [...] , ' cmp_function ') with index to check the difference set of arrays, using callback function to compare data and indexes

Array_udiff_assoc ($arr, $arr 2, [...], ' cmp_function ') the difference set with the index check array is compared with the callback function comparison data key name

Array_intersect ($arr, $arr 2[...]) Returns an array $arr the intersection of key names with other arrays

Array_intersect_assoc ($arr, $arr 2[...]) returns an array $arr the intersection of the other arrays and compares the key names, the index does not change

Array_intersect_uassoc ($arr, $arr 2 [...], ' cmp_function ') the intersection of an array with an index check, using a callback function, to compare the index

Array_intersect_key ($arr, $arr 2 [...]) compare the intersection of an array with a key name

Array_intersect_ukey ($arr, $arr 2 [...], ' cmp_function '); Computes the intersection of an array using a callback function to compare the key names

Array_uintersect ($arr, $arr 2 [...]. ' Cmp_function ') Compare the intersection of the array with the callback function to compare the data

Array_uintersect_assoc ($arr, $arr 2[...], ' cmp_function ') compare data with a callback function with the intersection of an index check array

Array_uintersect_uassoc ($arr, $arr 2 [...] ' Cmp_function ') with the intersection of the index check array, using the callback function to compare the data and the index
