I am not sure if I understand why using single quotes is faster when it seems like you have to go through more work than just having double quotes take care of it all.

echo “This is an example using a fake $variable.”;

as opposed to:

echo ‘This is an example using a fake’ . $variable . ‘.’

Can anyone answer that? Does Jeff mean it is slightly quicker because it is just one keystroke instead of two?

Since I am starting out, I want to figure out the best process so I can form form good habits.

If anyone knows, please tell.

@Shane Sponagle
thanks i’ve noticed that,was just a copy-paste error but my problem here is not the echo thing is the whole heredocs block
i solved thanks to Dean, basically i have to watch the last EOT; and be sure there is NO white space on that line
thanks!

@Brenelz:
“For the lines of:
$myvar = << EOF;

You have to make sure that there is no whitespace on these lines.”

The only line you have to watch out for is the EOF; – there can be no whitespace on this line.

If you indent your code and you have a heredoc inside an if statement, you must make sure that EOF; is not indented.

Also it’s not possible to use constants inside a heredoc statement which can be a pain sometimes.

Because I don’t intermix PHP and HTML (except for echoing out variables), I often use heredoc to build large blocks of html and then echo out the variable into the html template.

Jeff,

I’m a newbie to all this and just want to thank you for these tuts. I’m not so terrified of php now. Thanks!

@pix you are setting one var $str but are echoing another $myString.
Try echo $str;
