PHP best way to echo variables [duplicate]

Question

I was watching a PHP tutorial and noticed that the teacher was adding varibles to his echo statements in a different way to me. This got me thinking, which way should I be using? Is one more correct than the other?

Here's what the teacher was doing

echo "Example " . $example;

Here's what I do

echo "Example $example";

My method works, but I don't want to get into any bad habits. Could someone please tell me which way I should be using (preferably with some evidence)?

they are both valid, but the first example is easier to read in most text editors and hence make changes to later. — David

You could also wrap your variable in {} - echo "Example {$example}"; — Darren

echo "Example ", $example; also works. note comma as the separator rather than a fullstop which is the concatenation operator. It is useful when dealing with strings which use the different types of qoute characters in a string. — Ryan Vincent

I think that the second version is more readable and less error prone, especially if you have more than one variable to concatenate. — tonethar

That's a good point. I think its tough to say if one is hands down better than the other. — Jonty Morris

According to the PHP.NET documentation, his way is proper.

http://php.net/manual/en/language.operators.string.php

echo "Example " . $example;
