PHP 忒聊 綴豖 ヶ輛 array_intersect_assoc (PHP 4 = 4.3.0) Description array_intersect_assoc() 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(). 瞰赽 1. array_intersect_assoc() example ?php $array1 = array ("a" = "green", "b" = "brown", "c" = "blue", "red"); $array2 = array ("a" = "green", "yellow", "red"); $result_array = array_intersect_assoc ($array1, $array2); /* $result_array will look like: Array ([a] = green) */? In our example you see that only the pair "a" = "green" is present in both arrays and thus is returned. The value "red" is not returned because in $array1 it's key is 2 while the key of "red" in $array2 it is 1. The two values from the key = value pairs are considered equal only if (string) $elem1 === (string) $elem2. In otherwords a strict type check is executed so the string representation must be the same. See also array_intersect(), array_diff() and array_diff_assoc(). 綴豖 れ萸 ヶ輛 array_flip 奻珨撰 array_intersect
