ArrayUtil::deep_compute_or_compare_array_diff() │ private static │ WC 1.0

Helper method to compare to compute difference between two arrays. Comparison is done recursively.

Method of the class: ArrayUtil{}

No Hooks.

Return

Array|true|false. The difference between the two arrays, or if array are same, depending upon $compare param.

Usage

$result = ArrayUtil::deep_compute_or_compare_array_diff( $array1, $array2, $compare, $strict );

$array1(array) (required)

First array.

$array2(array) (required)

Second array.

$compare(true|false) (required)

Whether to compare the arrays. If true, then function will return false on first difference, in order to be slightly more efficient.

$strict(true|false)

Whether to do string comparison.
Default: true
