意外的T_REQUIRE_ONCE应该是预期的

Question

<?php

/*
 * userprofile.php
 * bshades.com
 * Coded by Orgy
 * rrawbb[at]gmail[dot]com
 */

require_once("inc/_top.php");

That's my code that's having a problem.

Here's the error message:

Parse error: syntax error, unexpected T_REQUIRE_ONCE in /home/blacksha/public_html/userprofile.php on line 1

As you can see, the require_once isn't even on line 1, so I have no idea what the problem could be.

Answer 1

NBSP. You had an invisible non-standard whitespace character before your require statement. That's the only reliable way to reproduce this error.

eval(    chr(0xA0) . ' require_once(1); ' );
      # that's nbsp

// PHP Parse error:  syntax error, unexpected T_REQUIRE_ONCE in 

0xA0/nbsp gets interpreted as bareword at that position. Basically the same as having a constant right in front of your statement:

ASCII require_once(123);
