如何在php中创建多维数组而不指定索引[关闭]

I am newbie programmer of php. How should I create array without specifying the size of array.I have tried using

$items = array();

How can add array as the element? Without having to specify the index. Thanks in advance for any feedback.

// define array

$item = array();

// adding multi dimensional array

array_push($item, array('name'=>'Pen','qty'=>1));

You may nest the array to even more levels by same method as mentioned above.

$items[] = 'my new item';

check the php manual

creating mutlidimesional array in php is easy stuff

<?php 
$shop = array( array("rose", 1.25 , 15),
               array("daisy", 0.75 , 25),
               array("orchid", 1.15 , 7) 
             ); 
?>
