I have an existing array to which I want to add a value.

I'm trying to achieve that using array_push() to no avail.

Below is my code:

$data = array(
    "dog" => "cat"
);

array_push($data['cat'], 'wagon');

What I want to achieve is to add cat as a key to the $data array with wagon as value so as to access it as in the snippet below:

echo $data['cat']; // the expected output is: wagon

How can I achieve that?

You don't need to use array_push() function, you can assign new value with new key directly to the array like..

$array = array("color1"=>"red", "color2"=>"blue");
$array['color3']='green';
print_r($array);


Output:

   Array(
     [color1] => red
     [color2] => blue
     [color3] => green
   )

Array['key'] = value;

$data['cat'] = 'wagon';

This is what you need. No need to use array_push() function for this. Some time the problem is very simple and we think in complex way :) .

<?php
$data = ['name' => 'Bilal', 'education' => 'CS']; 
$data['business'] = 'IT';  //append new value with key in array
print_r($data);
?>

Result

Array
(
    [name] => Bilal
    [education] => CS
    [business] => IT
)
