title: Inserting the date+time into a subject of an email
body: <p>How can I insert the date and time at the start of the subject e.g.</p>
  
  <p>the date('d-m-Y h:m:s') in the code doesnt function and returns this error: Parse error: syntax error, unexpected T_STRING</p>
  
  <pre><code>&lt;?php
      mail('joe@example.com', '"date('d-m-Y h:m:s')" Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');
  ?&gt;
  </code></pre>
  
  <p>This code works: (without the date and time)</p>
  
  <pre><code>&lt;?php
      mail('joe@example.com', 'Daily Backup: example.com', 'Download your daily backup from this link: http://example.com/backups/backup.zip');
  ?&gt;
  </code></pre>
  
  <p>Thanks for the help!</p>
