Delve into PHP array_multisort_php tutorials

For first-time learning

Like this array_multisort ($arr 1, $arr 2, $arr 3); By default, all arrays are sorted in ascending order, and if you want to $arr2 in descending order and compare them as strings, write:

Array_multisort ($arr 1, $arr 2, Sort_desc, sort_string, $arr 3);

Each array can be followed by a sort order flag or a sort type flag, or both flags appear at the same time. However, each sort flag can only appear after each array.

PHP array_multisort sort order flag:

Sort_asc-Sort by ascending order (default)

Sort_desc-Sort by descending order

PHP Array_multisort Sort Type flags:

Sort_regular-Compare items by usual method (default)

Sort_numeric-Compare items by value

Sort_string-Compare items by string
