(PHP 5)
array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
Opis
array_intersect_uassoc() returns an array containing all the values of array1 that are present in all the arguments. Note that the keys are used in the comparison unlike in array_intersect().
The index comparison is done by a user supplied callback function. It must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.
Parametry
- array1
-
Initial array for comparison of the arrays.
- array2
-
First array to compare keys against.
- array
-
Variable list of array arguments to compare values against.
- key_compare_func
-
User supplied callback function to do the comparison.
Zwracane wartości
Returns the values of array1 whose values exist in all of the arguments.
