JFab Posted April 1, 2010 Report Share Posted April 1, 2010 Hello Killersites, This is my first [relative] thread that might even help some of you. You may have been wondering, "What is the difference between Echo and Print?". I'm here to answer you that! You may notice that these two scripts do identically the same thing: <?php print "Hello World!"; ?> <?php echo "Hello World!"; ?> The only difference between these two scripts is that I use "print" rather than "echo", vice versa. I find that most old-fashioned programmers use 'print' rather than 'echo', due to the use in Java and C++, however in C++ it is actually called 'printf'. They both do the same exact thing, so why are there two!? Read more (learnphponline article) Quote Link to comment Share on other sites More sharing options...
falkencreative Posted April 1, 2010 Report Share Posted April 1, 2010 I do remember reading somewhere that echo was slightly faster, but I don't think I ever saw statistics that backed it up. Thanks for posting. Quote Link to comment Share on other sites More sharing options...

Thanks for posting. No problem echo is slightly faster, but not a worry if your in a habit of using print. I understand a lot of programmers coming from C still accidently use 'printf' instead of 'print' thinking it's the same function, hehe.

Wickham Posted April 1, 2010 Report Share Posted April 1, 2010 I looked to see if one was deprecated, but it seems that both are still valid. If you look at the php.net/manual pages, echo (PHP 4, PHP 5) echo — Output one or more strings Description void echo ( string $arg1 [, string $... ] ) print (PHP 4, PHP 5) print — Output a string Description int print ( string $arg ) there are small differences. Echo can be used for more than one string and the code is different. I use echo because that's what Stefan's video tutorial uses! Also I think there might be some confusion using print where people might think that it's supposed to start a computer's printer! Could someone please explain the difference between void echo ( string $arg1 [, string $... ] ) and int print ( string $arg ) Quote Link to comment Share on other sites More sharing options...
krillz Posted April 1, 2010 Report Share Posted April 1, 2010 (edited) Well PHP was made to make the move from one language to PHP as smooth as possible, that's why there are a lot of functions doing the same thing with different names.. and depending on from what language you emigrated from you find people using the different styles. And that's what I like about PHP so many different styles you can use, and you pretty much find fimiliar ways/functions in it from java, c, perl etc. Anyway about the print and echo difference: The print function .. or well it's not a function but a language contruct, returns a int value whereas echo returns no value that is it's a void function. Thus the difference in speed. But still it's the way you code that determine the speed of how the code works. So echo "String 1"."String2"; is a lot slower than just doing echo on one string as the two strings need to be merged into one. to not screw the time benefit of echo, you should use it's ability to handle multiple strings at once echo "String1", "String2", "String3"; is the correct way to go, and in a impressive loop this method would save us a a few seconds in the long run. So to sum this up, small writing to the screen, let say one liners there is no noticable difference between print and echo. It's when you start outputning multiple strings at once that you start noticing a difference. Edited April 1, 2010 by krillz Quote Link to comment Share on other sites More sharing options...
