What's the difference between PHP echo() and PHP print(), especially in the execution time?

echo
hello world
processing time for a hello world program = 0.030235052108765

print
hello world
processing time for a hello world program= 3.7908554077148E-5

printf
hello world
processing time for a hello world program= 3.504753112793E-5

i hope this answers your question

Bro
In all your php scripting forget "print" always use "echo"
With single or double quotes depending on the content of the echo.

In Php print is like homo erectus and echo is like homo sapiense
Bottom line
Never use print in your php life bc there is always an echo.

It is not that straight-forward as to just say 'Use echo'.

Apparently( I say 'apparently' because I am yet to test this and as such can not say it authoritatively) echo is faster because it doesn't set a return value on execution but I think that there are other factors that you should take into consideration:

It has some comments regarding the usefulness of the print statement and maybe you would want to look at that before deciding to use echo

I think in Output Buffering there's a difference

I hardly use echo/print/printf due to template engine (smarty), my best friend is var_dump and print_r for debugging . but i think echo is faster. just develop your own coding standard.
