best way to echo?

[GRUMBLE]

well it seems as if i have these options to output something onto the screen:

echo "hello $name !";

echo "hello ".$name.". !";

echo 'hello '.$name.' !';

which one is the best way to do it? concerning performance.

also, what about "print"? is it any better?

Use whichever one is easier. In your example, that's the first one.

Performance-wise there's not going to be much of a difference between any of them. Don't worry about performance for simple echo type stuff, unless it's something like this:

$mystring = "Some stuff.";
$mystring .= " Some more stuff.";
$mystring .= " And more stuff still.";
echo $mystring;

would be more efficient as this:

echo "Some stuff.";
echo " Some more stuff.";
echo " And more stuff still.";

The first one is slower because it has to copy the string around a bunch. But even then it's not going to be much of a difference.

Don't worry about performance unless you actually have a performance problem. You'll end up optimizing the wrong things (like echo statements).

thank you!

personally i always use method three. no performance enhancer should be overlooked in my opinion.

my personal preference:

print "hello " . $name . "!";

more than on line:

print "hello " . $name . "!
I never ever use 2 print statements in a row, since i think this is just waste of code.
Right - waste of code...";

but it you're going to use double quotes anyways you might as well put your variables inside the quotes.... it wont slow it down any. it's already parsing for variables in there, why bother not putting any in there? the only problem with single quotes is escape codes and i define a constant for each one (usually the letter of the escape code capitalized i.e N is "\n").

i prettu much use the quotes around variables for consistency and easiere readability. i just found it much easier to maintain code written like this.
