I took the code from http://pastie.org/523020 and I get much different results than they do. 0.043325901031494 for period concatenation and 0.034106969833374 with commas. Not sure where they get the 1.071463108062710 for commas. Using their test, I found commas to be faster.

if we use print(“hello”+5);
then output will be 5 only bcoz it take only 1 argument.

But with echo we can do like this:-
$a=5;
echo “hello”.$a;

output will be hello5.

Hmm, for some reason, when I try Nicholas’s comma-vs-concat test, the commas are consistently (slightly) faster. Also I had to add ‘flush();’ at the end of the PHP line. (php 5.2.0 on SuSE 10.2)

php -d implicit_flush=off -r ‘$s=microtime(true); for($i=0;$i<100000;$i++) echo "omgwtf","bbq","\n"; echo microtime(true)-$s; flush();' | fgrep -v "omg"
0.069497108459473

php -d implicit_flush=off -r '$s=microtime(true); for($i=0;$i<100000;$i++) echo "omgwtf"."bbq"."\n"; echo microtime(true)-$s; flush();' | fgrep -v "omg"

Yes you are right but instead of (,) use (.) and it Will add the statements.

I don’t think this is the reason why most developers use echo.

I use print because I don’t know of an echo equivalent for print_r() which is exceedingly helpful for troubleshooting purposes. Using echo for strings but then print_r() for arrays feels awkward to me.

@Nicolas Connault
Nice one about the dot vs. comma. No need to rewrite anything.
