I am trying to make a webpage that will take user input and add it to a .txt file. It is supposed to work like this webpage http://150.216.54.86:808/homework8/AirlineSurvey.html Why am I receiving "Parse error: syntax error, unexpected ';'" on line 27?

<?php
$WaitTime = addslashes($_POST["wait_time"]);

$Noise = addslashes($_POST["noise"]);
if (empty($WaitTime) ||
    empty($Friendliness) ||
    empty($Space) ||

Answer 1

You've missed a close parenthesis ) at your flock($SurveyFile, LOCK_UN;, that's why you are receiving parse error.

It should be like this flock($SurveyFile, LOCK_UN);
