Can we declare the array's length first instead of directly input the data ?

Question

set the length of the array

Answer 1

Just fill the array with empty strings or 0s... example if you wants an array of length 10:

<?php
$cars = array();
for ($x = 0; $x <10; $x++) {
    $cars[$x] = "";
} 
?>

Answer 2

so technically we can't do like what we do in java ?

String [] abc = new String [ length of the array]

Answer 3

that's my understanding based on the way we initialize the array.
