Proper form

Drebin

Example 1
echo "$tireqty tires <br>";

Example 2
echo $oilqty.' bottles of oil<br>';

Which way is more correct? I like using the format of first example because I don't have to worry about concatenating. I know that for this to work I have to use double quotes.

Would I run into any problems using this form of coding if I try to code more complex stuff?

You'll run into trouble with the first example if you use superglobals inside the string.

like lord said, if you use the predefined globals such as:
$POST['var']
$GET['var']
$SERVER['var']
then you will need to encapsulate them into ".."
eg:
".$POST['var']."
".$GET['var']."
".$SERVER['var']."

echo "Post Var = ".$_POST['var']."";

Or enclose them in braces.

oo never knew about braces
thnx Lord

No prob. Personally, I use the concatination method for every variable/string combination, regardless if it's a superglobal. The key is to just adopt one of the standards, and stick with it.

I see. I had a feeling that I wouldn't be able to use the format in the first example all the time. Thanks for the info.
