Considerations for Array_diff functions

array_diff- Calculating the difference set of an array

Description

Array array_diff ( array $array1 , array $array2 [, array $... ]) compares the values returned in array1 but not in array2 any other parameter array 。 Note The key name remains unchanged.

Note: This function examines only one dimension in a multidimensional array. If you want to compare a deeper dimension to another function, today's work meets the need, so write a function to compare the deeper dimensions.

The above describes the Array_diff function, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
