Question

I have this code, but I'm getting

Parse error: syntax error, unexpected '<<' (T_SL) on line 48

**That means especially that the identifier may not be indented, and there may not be any spaces or tabs before or after the semicolon** https://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc — user3783243, Apr 05 '21 at 16:03

This also would open you to XSS injections and I don't know when a password would ever be outputted. — user3783243, Apr 05 '21 at 16:05

I think you have blank space after EOD, when there should be none. Please remove it and retry. Also remove any proceeding blank space before the ending EOD;

Solution: Remove trailing space after ALL <<<EOD and remove preceding whitespace before ALL the terminating EOD;

THX for your help. But, when i remove blank space after EOD there's another error. Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) on line 46 – 김다빈 Apr 05 '21 at 16:10
Did you also remove the space before the terminiating EOD; ? – Rakesh Gupta Apr 05 '21 at 18:50

While you could use HEREDOC it poses an issue when it comes to spaces as another answer already points out. The way that I would approach it is to use something like the following which works and is easier to read:

<center><br><br>
    ID: <?php echo $_POST['user_id']; ?>
    PW: <?php echo $_POST['user_pw']; ?>
</center>

Reflecting the user's password back to them on the page isn't advised unless you are just getting a feel for how data moves around pages.
