Problem with <<<_END php tag in IE8
I'm designing a fairly simple reporting system. Right now using php(and later some Jquery) to let user log in and calculate totals and post to a database. My problems began of course when I tested the page in IE8. It has major problems with the echo <<<_END statement at line 75. Anyone know an alternate to coding the nested HTML in the PHP besides this. any help is appreciated.

The Heredoc identifier must on a line of itself and must be the only thing on this line (including indentation and such). Remove the leading whitespace and make sure the newline is direct after _END;.
However, in your case I suggest you to just leave the PHP-mode to output the plain html
For example instead of
echo <<<_END
<form action = "sqltest.php" method="post"><pre>
AssessmentID <input type="text" name="AssessmentID" /><br>
Date <input type="text" name="Date" /><br>
Inspector <input type="text" name="Inspector" /><br>
PlantAssist <input type="text" name="PlantAssist" /><br>
Safety_Total <input type="text" name="Safety_Total" /><br>
<input type="submit" value="ADD RECORD" /><br>
</pre></form>
_END;
this
?>
<form action = "sqltest.php" method="post"><pre>
AssessmentID <input type="text" name="AssessmentID" /><br>
Date <input type="text" name="Date" /><br>
Inspector <input type="text" name="Inspector" /><br>
PlantAssist <input type="text" name="PlantAssist" /><br>
Safety_Total <input type="text" name="Safety_Total" /><br>
<input type="submit" value="ADD RECORD" /><br>
</pre></form>

Its usually more readable and many IDEs are capable to recognize it and highlight the "other stuff" as html.
As the commenter says, the HEREDOC (the <<< and _END;) bits are server side PHP related, the browser should know nothing of them.
One major, easily forgettable golden rule of HEREDOC tags is that the closing tag CAN NOT BE INDENTED, EVER! Or it will break.
Heres a read about them:
http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc
If its really breaking things, and its really this thats doing it (though, no reason why it should be) - remember its just a block of output, so you could replace it at a stroke with:
$out = "blah blah";
$out .= "more blah blah";
$out .= "more blah blah";
$out .= "more blah blah";
$out .= "more blah blah";
echo $out;
加载中,请稍侯......
