title: Array push with associate array
body: <p>If I am working with an associate array like such:</p>
  
  <pre><code>Array ( [Username] =&gt; user 
          [Email] =&gt; email 
        )
  </code></pre>
  
  <p>and I want to add an element to the end, I would think to do:</p>
  
  <pre><code>array_push($array, array('Password' =&gt; 'pass'));
  </code></pre>
  
  <p>However, this leaves me with:</p>
  
  <pre><code>Array ( [Username] =&gt; user 
          [Email] =&gt; email
          Array ( [Password] =&gt; pass )
        )
  </code></pre>
  
  <p>How can this be avoided so I end up with:</p>
  
  <pre><code>Array ( [Username] =&gt; user 
          [Email] =&gt; email
          [Password] =&gt; pass
        )
  </code></pre>
  
  <p>Much appreciated!</p>
