inserting to multidimensional array php

Question

Im trying to insert variables to the array by using foreach loop. This is the foreach loop im trying to implement with

foreach($rows as &$url) {
      $link = array("url");
      array_push($url, "hello World"); 
}

And this is the result I get.

Array
(
    [0] => Array
        (
            [cat_id] => 1
            [id] => RT
            [name] => root
            [parent] => 0
            [0] => hello World
        )

    [1] => Array
        (
            [cat_id] => 2
            [id] => CI
            [name] => Civil & Interior Works
            [parent] => 1
            [0] => hello World
        )

)

but i would like the result to be like this.

Array
(
    [0] => Array
        (
            [cat_id] => 1
            [id] => RT
            [name] => root
            [parent] => 0
            [url] => hello World
        )

    [1] => Array
        (
            [cat_id] => 2
            [id] => CI
            [name] => Civil & Interior Works
            [parent] => 1
            [url] => hello World
        )

)

If i pass the variable $link = array("url"); to array_push($link, "hello World"); nothing happens.

if I remove the referance from the foreach($rows as &$url) the loop does not work at all. Please advise.

Just add a value under the required key:

foreach($rows as &$row) {
    $row['url'] = "hello World";
}

thanks that worked... so array_push was not required ??

array_push adds an element in the end of array, it doesn't care about keys. If you need a specific key - use ['key'] syntax.

I noticed something... if i use &$row referance ... I lose one loop... the last element item inserted dis not picked up.
