title: Parse error: syntax error, unexpected 'unset' (T_UNSET)
body: <p>I am using simple php unset() function to remove and index of array but it's showing the following error:</p>
  <pre class="lang-php prettyprint-override"><code>Parse error: syntax error, unexpected 'unset' (T_UNSET)
  </code></pre>
  <p>Here is my erroneous code:</p>
  <pre class="lang-php prettyprint-override"><code>echo $totalArray = unset($linkExtHelp[0]);
  </code></pre>
  <p>Thanks in advance.</p>
