Store each number in array
<p>Hey guys I'm new in php and I'm trying to store the numbers from a input into a string, something like this.</p>

<p>let's say that the input stores the number 1234:</p>

<pre><code>$input = 1234;
</code></pre>

<p>So I wan't to store a single digit and not the whole number in the array like:</p>

<pre><code>$arr[0] = 1;
$arr[1] = 2;
$arr[2] = 3;
...
</code></pre>

<p>How can I do that?</p>
