To reset the keys of all arrays in an array:

<pre><code>$arr = array_map('array_values', $arr);
</code></pre>

In case you just want to reset first-level array keys, use <a href="http://php.net/manual/en/function.array-values.php" rel="noreferrer"><code>array_values()</code></a> without <a href="http://php.net/manual/en/function.array-map.php" rel="noreferrer"><code>array_map</code></a>.

Here you can see the difference between the way that <a href="https://stackoverflow.com/users/476/deceze">deceze</a> offered comparing to the simple <code>array_values</code> approach:

The Array:

<pre><code>$array['a'][0] = array('x' =&gt; 1, 'y' =&gt; 2, 'z' =&gt; 3);
$array['a'][5] = array('x' =&gt; 4, 'y' =&gt; 5, 'z' =&gt; 6);

$array['b'][1] = array('x' =&gt; 7, 'y' =&gt; 8, 'z' =&gt; 9);
$array['b'][7] = array('x' =&gt; 10, 'y' =&gt; 11, 'z' =&gt; 12);
</code></pre>

In <code>deceze</code> way, here is your output:

<pre><code>$array = array_map('array_values', $array);
print_r($array);

/* Output */

Array
(
 [a] =&gt; Array
 (
 [0] =&gt; Array
 (
 [x] =&gt; 1
 [y] =&gt; 2
 [z] =&gt; 3
 )
 [1] =&gt; Array
 (
 [x] =&gt; 4
 [y] =&gt; 5
 [z] =&gt; 6
 )
 )
 [b] =&gt; Array
 (
 [0] =&gt; Array
 (
 [x] =&gt; 7
 [y] =&gt; 8
 [z] =&gt; 9
 )

 [1] =&gt; Array
 (
 [x] =&gt; 10
 [y] =&gt; 11
 [z] =&gt; 12
 )
 )
)
</code></pre>

And here is your output if you only use <code>array_values</code> function:

<pre><code>$array = array_values($array);
print_r($array);

/* Output */

Array
(
 [0] =&gt; Array
 (
 [0] =&gt; Array
 (
 [x] =&gt; 1
 [y] =&gt; 2
 [z] =&gt; 3
 )
 [5] =&gt; Array
 (
 [x] =&gt; 4
 [y] =&gt; 5
 [z] =&gt; 6
 )
 )
 [1] =&gt; Array
 (
 [1] =&gt; Array
 (
 [x] =&gt; 7
 [y] =&gt; 8
 [z] =&gt; 9
 )
 [7] =&gt; Array
 (
 [x] =&gt; 10
 [y] =&gt; 11
 [z] =&gt; 12

Simply do this: <code>mixed reset ( array &amp;$array )</code>

The question is how to reset key e.g. for an array:

<pre><code>Array ( 
 [1_Name] =&gt; Array ( 
 [1] =&gt; leo 
 [4] =&gt; NULL 
 ) 
 [1_Phone] =&gt; Array ( 
 [1] =&gt; 12345 
 [4] =&gt; 434324
 ) 
)
</code></pre>

reset to :

<pre><code>Array ( 
 [1_Name] =&gt; Array ( 
 [0] =&gt; leo 
 [1] =&gt; NULL 
 ) 
 [1_Phone] =&gt; Array ( 
 [0] =&gt; 12345 
 [1] =&gt; 434324
 ) 
)
</code></pre>
