title: PHP: Split string into 2 strings based on a comma delimited count of X
body: <p>So, I have a comma delimited string which I want to split into two strings after count of x commas. </p>
  
  <p>So, if my string was as follows:</p>
  
  <blockquote>
    <p>temp1, temp2, temp3, temp4, temp5, temp6, temp7, temp8, temp9, temp10</p>
  </blockquote>
  
  <p>I want to split it into two strings after a count of 4 commas, I would expect:</p>
  
  <pre><code>$string1 = 'temp1, temp2, temp3, temp4, ';
  
  $string2 = 'temp5, temp6, temp7, temp8, temp9, temp10';
  </code></pre>
  
  <p>How can I achieve this in PHP?</p>
