To create a simple array or a multidimensional array with defined size and null values??, use this expression:
<?php
$SimpleArray = array_map(function($n) { return null; }, range(1, 3) );
$MultiArray = array_map(function($n) { return array_map(function($n) { return null; }, range(1, 2) ); }, range(1, 3) );
var_dump($SimpleArray);
var_dump($MultiArray);
?>
>>$SimpleArray
array(3) {
[0]=> NULL
[1]=> NULL
[2]=> NULL
}
>>$MultiArray
array(3) {
[0]=> array(2) {
[0]=> NULL
[1]=> NULL
}
[1]=> array(2) {
[0]=> NULL
[1]=> NULL
}
[2]=> array(2) {
[0]=> NULL
[1]=> NULL
}
}
?>
