bw_array_get() – Return the array[index] or array->index (for an object) or a default value if not set

Description

Return the array[index] or array->index (for an object) or a default value if not set

Note: This code is slightly more efficient with the default being assigned in the else than when there is just one assignment of $value = $default right at the start where slightly more is 2 or 3 microseconds – measured on a laptop.

Usage

bw_array_get( $array, $index, $default );

Parameters

$array

( mixed ) required –

$index

( mixed ) required –

$default

( mixed ) optional –
