Hello guys, i was just doing some testing and was wondring if echo is faster
than print or print_r. I think since echo is a language construct and
print_r is a function, echo is faster.

Please let me know.

Thanks

People in the past have said that echo and print as actually the same call
within PHP core system. I have never dug through the core code that makes up
PHP so I cannot confirm this claim.

print_r on the other hand is a totally different thing. It takes and processes
strings, arrays, objects, etc... So, with that said, it will be much slower. It
has to detect what type of object it is and then deal with all the pieces. And
then in the end, output everything to the screen.

Hey Brandon, do you think you could spend some time reading the Google
talk manual? It's kind of irritating seeing your "Brandon Rampersad
wants to chat" spam on the list repeatedly.

As for which is faster... your assertion is right.

Cheers,
Rob.

biggest difference:

http://php.net/print
print() returns 1, always - which means it's returning a value

http://php.net/echo
doesn't return anything

Sara Golemon's "how long is a piece of string" blog post
(http://blog.libssh2.org/index.php?/archives/28-How-long-is-a-piece-of-string.html
which appears to be down or something right now) I believe shows the
different opcodes (using VLD - http://pecl.php.net/package/vld)

This is a micro-level optimization. I believe echo is "faster" or
"less intensive" because it does not need to return a value, but on
modern CPUs saving a couple ops is probably not that big of a deal
(even thousands of them) - I think the general consensus is "there is
really no difference" last I saw. Only very very small optimizations.
