I apologize, an addendum: Mozilla *Firefox* 1.0 PR. Previous Comments: ------------------------------------------------------------------------ [2004-09-25 07:03:24] jed at jed dot bz I am the submitter of Keith's failed post. The problem only produces itself in Mozilla 1.0 PR. When I viewed this page in Internet Explorer, the problem was not there. As proof, I have taken a screenshot: http://labs.jed.bz/phpbug.png PHP developers are too quick to mark bugs bogus. Please review this bug's status. ------------------------------------------------------------------------ [2004-09-25 06:53:52] keithm at aoeex dot com This bug is not bogus. We are experiencing it semi-randomly with our pastebin code at http://dalphp.shoggoth.net/pastebin.php (http://dalphp.shoggoth.net/pastebin_view.php?356 is one post being affected) The code that is paste is generating the warning for \'s which are valid. In this case, the \ in the \n in the print statements. Here's some debugging code/output I added to see if this was a bug or not. -=-=-= code -=-=-=-=- $src=implode("\n", $Source); echo '<!-- Source: ', NL, $src, '-->'; if (strpos($src, '<?php') !== false || strpos($src, '<?') !== false){ $source=highlight_string($src, 1); echo '<!-- Source 2: ', NL, $source, ' -->'; $source=str_replace(array('<code>', '</code>'), '', $source); } else { $source=nl2br(htmlentities($src)); } echo $src; -=-=-=-=-=-=-=-=-=-=- -=-=-= output -=-=-=-=- <!-- Source: <?php /* Trying to figure out wtf is thrown when an array is accessed out of bounds. */ print "Before!\n"; try { print "Trying!\n"; $x = array(1, 2, 3); print_r($x); $y = $x[3]; print_r($y); } catch(Exception $e) { print "Cought!\n"; print_r($e); } print "Done!\n"; /* Expected output: * Before! * Trying! * Array ( etc. * Cought! * Object ( etc. * Done! * * Actual output: * Before! * Trying! * Array ( etc. * Done! */ ?>--><!-- Source 2: <code><font color="#000000"> <font color="#0000BB"><?php<br /><br />/* Trying to figure out wtf is thrown when an array is accessed out of bounds. */<br /><br />print </font><font color="#DD0000">"Before!<br /> <b>Warning</b>: Unexpected character in input: '\' (ASCII=92) state=1 in <b>/home/trollboy/public_html/dalphp/pastebin_view.php</b> on line <b>153</b><br /> n";<br /> <br />try {<br /> print "Trying!<br /> <b>Warning</b>: Unexpected character in input: '\' (ASCII=92) state=1 in <b>/home/trollboy/public_html/dalphp/pastebin_view.php</b> on line <b>153</b><br /> n"</font><font color="#0000BB">;<br /> $x = array(1, 2, 3);<br /> print_r($x);<br /> $y = $x</font><font color="#007700">[</font><font color="#0000BB">3</font><font color="#007700">]</font><font color="#0000BB">;<br /> print_r($y);<br /></font><font color="#007700">}</font><font color="#0000BB"><br />catch(Exception $e) </font><font color="#007700">{</font><font color="#0000BB"><br /> print </font><font color="#DD0000">"Cought!<br /> <b>Warning</b>: Unexpected character in input: '\' (ASCII=92) state=1 in <b>/home/trollboy/public_html/dalphp/pastebin_view.php</b> on line <b>153</b><br /> n"</font><font color="#0000BB">;<br /> print_r($e);<br /></font><font color="#007700">}</font><font color="#0000BB"><br /><br />print </font><font color="#DD0000">"Done!<br /> <b>Warning</b>: Unexpected character in input: '\' (ASCII=92) state=1 in <b>/home/trollboy/public_html/dalphp/pastebin_view.php</b> on line <b>153</b><br /> n"</font><font color="#0000BB">;<br /><br />/* Expected output:<br /> * Before!<br /> * Trying!<br /> * Array ( etc.<br /> * Cought!<br /> * Object ( etc.<br /> * Done!<br /> *<br /> * Actual output:<br /> * Before!<br /> * Trying!<br /> * Array ( etc.<br /> * Done!<br /> */<br /><br />?></font> </font> </code> --> -=-=-=-=-=-=-=-=-=-=-=- As you can see, the highlight_string call is causing the warning to be injected into the source where they should not be. The code is fine under normal circumstances. ------------------------------------------------------------------------ [2003-10-02 20:56:57] [EMAIL PROTECTED] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The warning you are seeing is a lexical parser warning, it cannot be avoided simply because it is the same parser as the one parsing normal PHP source. If PHP were to execute the file it too would strip/ignore the \ character. ------------------------------------------------------------------------ [2003-10-02 17:03:45] kjartan at zind dot net Doing @highlight_string seems to work to, but it strips the \. Might not fixing, but it still seems like a bug. ------------------------------------------------------------------------ [2003-10-02 16:51:07] [EMAIL PROTECTED] If you just want to suppress warnings, error_reporting(0) might help you. I'm not sure if this needs to be fixed anyhow though... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
