Undefined Constant/Index

[ParaChase]

Hello everybody,

 

I realize that there have been several threads on this already, but I am still wondering about receiving undefined constants/indexes. In the other examples that I have seen, it involved adding quotation marks. However, I don't think that my code has that problem:

<?php
		echo("<pre>");
		$d = null;
		$offset = -4;
		echo("MARCH <br/>");
		echo("  S  M  T  W  H  F  S <br/>");

		for ($row=0; $row<=4; $row++) {
			for ($col=0; $col<7; $col++) {
				$d = $col + $row*7 + 1 + $offset;
				if ($d<10) {
					echo(" ");
				}
				echo(" ");
				if ($d<32 && $d>0) {
				echo(d);
				}
				if ($d<1)
					echo(" ");
			}
			echo("<br/>");
		}

		echo("</pre>");

?>

 

This is code that I'm using to make a calendar. I'm not asking for code. I just want some help on why this undefined constant happens and what I can do to get rid of it.

 

Thank you so much.

echo(d);

ooh I see. It's supposed to be:

echo($d);

Yup, the error message should've given you a line number. Using that, you could have easily figured this out on your own
