Extract decimal or Integer from a string in php
<p>Eg:</p>

<pre><code>$str .= "Additional tax(2.34)";
$str .= "Additional tax(3)";
</code></pre>

<p>Can anyone help me up to extract the number from the string. I need an array format like this </p>

<pre><code>Array ( [0] =&gt; 2.34 [1] =&gt; 3 );
</code></pre>
