If I am working with an associate array like such:

Array ( [Username] => user 
        [Email] => email 
      )

and I want to add an element to the end, I would think to do:

array_push($array, array('Password' => 'pass'));

However, this leaves me with:

Array ( [Username] => user 
        [Email] => email
        Array ( [Password] => pass )
      )

How can this be avoided so I end up with:

Array ( [Username] => user 
        [Email] => email
        [Password] => pass
      )

Much appreciated!

You are using an associative array so you just set the key/value pair like this.

$array["Password"] = pass;

I think you may need to review the difference between an array and an associative array. For example if I ran the same command again with a different value it would overwrite the old one:

$array["Password"] = "overwritten";

Giving you this

Array ( [Username] => user 
        [Email] => email
        [Password] => "overwritten"
      )

Which judging by your question is not what your expecting

Try out array_merge instead: 

$array = array('Username' => 'user', 'Email' => 'email'); 
$array = array_merge($array, array('Password' => 'pass'));

This produces the array:

array('Username' => 'user', 'Email' => 'email', 'Password' => 'pass');

  • You can also do this as a shortcut `$array += array('Password' => 'test');` but be warned it won't override Password if already set. Also, I wouldn't personally do it. Just seemed like an addtional FYI. – brady.vitrano Jul 07 '11 at 23:15

Associative arrays aren't designed to have their keys in order. You can add an element via

$array['Password'] = 'pass';

Generally, with an associative array you don't have control over the order of the elements.

The elements can be in any order.

However I've found php keeps the order that you add them.

So just do $myarra["name"] = "password"
