I'm not sure if this has been addressed in any of the other replies, but I felt it was worth mentioning: Be careful and pay attention to whether you are using single quotes ( ' ) or double quotes ( " ) in your echo statements! $var = 'asdf'; echo 'hey, $var'; // "hey, $var" echo "hey, $var"; // "hey, asdf" ...and if you're using single or double quotes elsewhere (i.e., assignment operations)... $var = 'asdf'; $othervar = 'blah$var'; // "blah$var" $anothervar = "blah$var"; // "blahasdf" $yetanothervar = "blah{$var}blah"; // "blahasdfblah" Double quotes, when not using "echo", can still parse variables for you. -- // Todd
