PHP array() array

array() creates an array, with keys and values. If the key is omitted when specifying the array, an integer key is generated that starts at 0 and increments by 1. To create an associative array with array(), use => to separate the keys and values.

To create an empty array, do not pass parameters to

array(): ​

$new = array();

Note: array()

is actually a language construct, usually It is used to define a direct array, but its usage is very similar to that of functions, so we also list it in the manual
