Actually, I can't even remember when I last used the regular print. There used to be a difference, but not really any more, I don't think. Or does print still not allow multiple arguments?... What do you guys use, and what is the advantage (if ther is any) of print over echo? And I am not talking about print_r or anything, just the regular print. :o) I use echo, because I'm old, and got in the habit, back when print() was a function and echo was a language construct, and only echo let you have as many args with commas as you wanted. But there's no significant difference, as far as I know.

There is a difference, echo is slightly faster. code used for benchmark: <? $start = microtime(TRUE); for ($i=0; $i<100000; ++$i) { print "ABC"; } echo sprintf("With print ($i): %0.3f\n",microtime(TRUE) - $start); $start = microtime(TRUE); for ($i=0; $i<100000; ++$i) { echo "ABC"; } echo sprintf("With echo ($i): %0.3f\n",microtime(TRUE) - $start); ?> it displays 100000 times ABC, first with the print command, and second with the echo command. Result: ABCABCABC<snip> print (100000): 0.085 ABCABCABC<snip> echo (100000): 0.076 It's not a lot, but since we are displaying data a lot, (most used function?) it will make a difference in really big scripts.
