title: preg_split String into Array at First Non-Numeric Character
body: <p>I have a string with some numbers and text and I'm trying to split the string at the first non-numeric character.</p>
  
  <p>For Example, I have a few strings like</p>
  
  <pre><code>$value = '150px';
  $value = '50em';
  $value = '25%';
  </code></pre>
  
  <p>I've been trying to split the string using preg_split and a little regex.</p>
  
  <p><code>$value_split = preg_split( '/[a-zA-Z]/' , $fd['yks-mc-form-padding'] );</code></p>
  
  <p>I'm able to get the first part of the string using <code>$value_split[0]</code>, for example I can store 150, or 50 or 25. I need to return the second part of the string as well (px, em or %).</p>
  
  <p>How can I split the string using preg_split or something similar to return both parts of the array??</p>
  
  <p>Thanks!</p>
