I sometimes recieve a parse error when loading script
<p>I don't know if this has happended to some of you developers before but sometimes when I reload a script on the browser, I receive this php error:</p>

<blockquote>
  <p>Parse error: syntax error, unexpected $end in /.../ on ...</p>
</blockquote>

<p>It will point to different line numbers on my script for every time it does appear and if I realod the script on the browser, then it loads the page successfully with no errors.</p>

<p>My question is though that why does this error sometimes appear when I load the script on the browser?</p>
