Pushing into a 2 dimensional array in php

Question

If i have an array with 2 dynamic values like this :

 $people = array(
    "george" => "smith"
);

How can i push into that in php?

I have tried

array_push($people, "john" => "smith");

EDIT :

I have tried what has been commented but adding a new key doesnt create a new entry in the array, there is only 1 value although there should be 3..

 $people = array();

foreach ($items as $item){

    $name = $item->getElementsByTagName('name')->item(0);
    $num = $item->getElementsByTagName('number')->item(0);
    $mess = $item->getElementsByTagName('message')->item(0);

    if($name != NULL && $num != NULL && $mess != NULL){
        $people[$num->textContent] = $name->textContent;

    }

}
 var_dump($people);

... What? What do you mean with "push into that"? You wanna add another value? — Epodax, Mar 29 '16 at 10:20
to which array do you want to push? give us a code that you have tried. — Syed mohamed aladeen, Mar 29 '16 at 10:20
The names come in dynamically so it would end up $people = array( "george" => "smith", "george2" => "smith2" ); — Gaz Smith, Mar 29 '16 at 10:22
Google php arrays and find out how arrays function. - And the array you have demonstrated so far, is not a 2 dimensional array, it's a simple flat array. — Epodax, Mar 29 '16 at 10:23

If new element has a defined key:

$people['newkey'] = 'newvalue';

Without any defined key:

$people[] = 'newvalue';

Array push but without key

array_push($people,'mark');

with key

$people['keytest'] = test;

In this case, array_push will not work because there is not next index. What you can do is:

$people['new_key'] = 'new_value';

But it will replace the old value with same key if exist. So you can handle it with isset function.

if(isset($people['new_key'])){
    // do some stuff here!
}
else{
    $people['new_key'] = 'new_value';
}

Fixed it by using

$people[] = array($num->textContent => $name->textContent);

By writing above code you just changed the structure of `$people` array. Now it will look like: array( array("key1" => "value1"), array("key2","value2")); just `var_dump($people)` OR `print_r($people)` – Ali Mar 29 '16 at 10:37
