[PHP] echo VS print : that's a cool behavior !
Hello everyone.
We all know the difference between print and echo, but has someone ever
tried to combine them together ??
Right, try this :
?php
echo coucou . print('v ' . print('u ' . print('toctoc ') . 'hihi ') ) .
'tata ' . print('zozo ' . print('pupu '));
And guess the result ...
Can someone explain it ?
( the result is : toctoc hihi u 1pupu zozo 1v 1tata 1coucou 1 )

That's not cool, that's a mess. Why doe sit happen the way it does?
First off, print() is a function so nesting functions means the
innermost functions get processed first, this is why the output has
mangled order. The 1's show up in the output because you're
concatenating the return value of the print() function which is true for
success.

Agreed it's a mess, and I don't know why anyone would do it, but
that's only part of the story. I don't think the OP was wondering
where the 1s came from; at least I'm not. I am wondering why it
displays:
toctoc hihi u 1pupu zozo 1v 1tata 1coucou 1
instead of
toctoc u 1hihi v 1pupu zozo 1coucou 1tata 1

Good call on the 1 return.

My bad, print is not a function, and so:
print( 'toctoc ' ).'hihi ';
is equivalent to:
print( 'tocktoc '.'hihi ' );
Parenthesis are option and only server to control precedence. But unlike
echo print does return a value.

Ah. I see. I knew they were optional, but I didn't know that when you
include them PHP evaluates ('toctoc') before it passes the value off
to print(). I just figured that with or without the parentheses it
would pass 'toctoc' to print() and return a result that would be
concatenated inline with the other values. I guess that's the part I
didn't understand about the difference between a function and a
language construct in PHP.
As for the OP, I still don't know why anyone would even dream of
creating code that does this other than to see what would happen if
we :-)

What do you guys use, and what is the advantage (if ther is any) of

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; $i10; ++$i) { print ABC; }
echo sprintf(With print ($i): %0.3f\n,microtime(TRUE) - $start);
$start = microtime(TRUE);
for ($i=0; $i10; ++$i) { echo ABC; }
echo sprintf(With echo ($i): %0.3f\n,microtime(TRUE) - $start);
?
it displays 10 times ABC, first with the print command, and second
with the echo command. Result:
ABCABCABCsnip
print (10): 0.085
ABCABCABCsnip
echo (10): 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.

This has been covered before. The difference actually depends on how
you're using it, rather than whether you use print or echo. For example,
your benchmark shows echo to be slightly faster, but the the following
script that I wrote last time this came up shows the opposite. The only
difference is that you're outputting a literal whereas I'm printing a
variable.
http://dev.stut.net/phpspeed/
At the end of the day there are more important things to worry about,
especially when you're talking in the region of 0.009 seconds per
100,000 calls it's not going to make anywhere near a significant
difference to any script you write, even really really big ones scripts.
To put it another way, you would need to make 10,000,000 calls for it to
extend the runtime of your script by 1 second. Granted you might have a
script that calls it 1000 times, meaning 10,000 requests to that script
would waste 1 second. But unless you're getting twitter-like levels of
traffic (they spike at over 11k hits a second) it's not worth worrying
about, and I'm guessing (hoping) their devs probably wouldn't care either.
Get over it and concentrate on the functionality and usability of your
code rather than insignificant details like this.

Interesting :)
I see there's no big difference between echo and print, but that
?=$x? is faster :)
I've learned (not only from this) that whatever you do in PHP is fast,
and that you don't need to optimize your code for speed. Unless you're
hitting 100k+ hits per hour. But even then it would only save you
maybe one hour per year.

I wouldn't go that far. It is definitely possible to write horribly
inefficient code with PHP. Believe me, I've inherited enough crap code
in my lifetime to testify to that.
My point was simply that you need to look at the numbers from benchmarks
in perspective, and when efficiency is concerned there's almost always
far bigger gains to be made than 0.009 seconds per 100,000 calls to
output something.

But what else would you use a lot in your code?
all commonly used things (like while, if, echo, etc) are just (nearly)
as fast as their alternatives (for, print, etc).
Other functions (like file/stream) might be some performance
difference, but you probably use this only a few times in your script.
So there's not a bigger performance difference then when optimizing
echo/print.

Optimising is not useless, and I've never said it is. However, you have to do so where it's going to have the biggest impact. What I'm basically saying is you should be optimising logic before even thinking about whether you're using the most optimised functions. Are you sure that your code doesn't do anything it doesn't need to? Do you do a whole load of initialisation for each request that could be cached in some way? Is every part of that initialisation needed for every page request, or should it be doing different things on different pages. IMHO, the kind of developer that gets hung up on details like echo or print is one that is unlikely to accomplish a lot in any given day. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] echo or print ?
Good morning fellow coders
I've been working with PHP for a little over 5 years now, and it even got me
a cute office and a good salary... but even though I can make a living off
of it, I am still wondering about a few little things.
Whenever I see people put their code up for review, I realize they mostly

print returns a result, echo doesn't. This makes echo slightly faster
than print, but I doubt theres any significant speed improvement using
echo instead of print.
I use echo, but thats just because its a habit.

Re: [PHP] echo or print ?
Me too. I use echo. Print is a function.
There's no significant difference between them. My advice: choose one,
and stick with it.

Guys, Jay asked a serious question (I think). Anyways, let's take this one
step further to something that I've really been wondering about.
(.. long bunch of HTML ..)
Jay asked ?=$Question?, then Tom said ? echo $Answer; ?. ?php
print 'Meanwhile a lot of others read it including '.$Strangers[0].',
'.$Strangers[2].', '.$Strangers[3].' and '.$Strangers[4].'.\n;
echo After a short while, among others, $Kirk[firstname] {$Kirk[lastname]}
also said his things.;
?
Point is, which of the inline printing style is preferred by you guyes. I
tend to use ?=$Var? a lot, since it reads easier but get into struggles
with myself when I do that multiple times in a row.

For example, on a news-page I call a function which returns an array with (non-layout) specific values. And it are those values that make it their way to ?=$News['Title']? and stuff like that.

Re: [PHP] echo or print
Rasmus Lerdorf
There is a difference between the two, but speed-wise it
should be irrelevant which one you use. print() behaves
like a function in that you can do:
$ret = print Hello World;
And $ret will be 1
That means that print can be used as part of a more complex
expression where echo cannot. print is also part of the
precedence table which it needs to be if it is to be used
within a complex expression. It is just about at the bottom
of the precendence list though. Only , AND, OR and XOR
are lower.
echo is marginally faster since it doesn't set a return
value if you really want to get down to the nitty gritty.
If the grammar is:
echo expression [, expression[, expression] ... ]
Then
echo ( expression, expression )
is not valid. ( expression ) reduces to just an expression
so this would be valid:
echo (howdy),(partner);
but you would simply write this as:
echo howdy,partner;
if you wanted to use two expression. Putting the brackets
in there serves no purpose since there is no operator
precendence issue with a single expression like that.

There is no real difference in common usage, print returns true always so you
can use it in weird situations otherwise echo is a tiny bit faster.
You can do stuff like this
if(isset($_GET['name'] print('DEBUG: received name set to
'.$_GET['name'].br\n)){
//normal processing here
}

Re: [PHP] echo vs print (was echo vs printf)
Ummm. I am not sure about either having a return value... but
print you have $points points;
and
echo you have $points points;
have identical output. You can drop a variable into an echo statement with
no problem

Subject: Re: [PHP] echo vs printf
i seem to remember reading somewhere that print acts like (is) a function,
presumably returning false if it cannot print to screen, whereas echo
just
dumps it.
also you can drop vars in print like
print you have $points points;
whereas to echo it you'd have to concatenate the string.

Why should I use printf instead of echo and vice versa?
printf print-formated
$a=12.3456;
echo $a, 'BR';
printf('%1.2fBR', $a);
12.3456BR
12.34BR
As for today I use printf mostly but I don't know why.
You prolly mean print; There may be some minor differences from echo,
but i've never seen 'em.
(i think they threw print in PHP to keep JAPHs happy).

[PHP] echo vs print
I have "Profession PHP Programming" and I see that echo() and print() are used alomst interchangeably. When should each one be used? Also, I see "?php" and "?" used. Is there a preference?

Is there a preference? ? is a short tag, ?php is not. ?php will always work, everywhere, always. This is what should be used. ? will most likely always work wherever your script may travel but keep in mind, this setting can be turned off. See : http://www.php.net/manual/en/configuration.php#ini.short-open-tag And how about "};" versus "}" to end a block? I see both. Don't do }; as it looks funny. Btw, I've never seen }; used within the manual.

RE: [PHP] Echo and Print
Hi, I cut paste this from an earlier e-mail from this list, hope it helps: - The print() function returns a boolean indicating the status of the call. If the write was successful, print() returns 1. If not, it returns 0. This can be used to detect when the client has closed the connection, and appropriate measures taken. The builtin echo does not provide this same service. This may be handy for you, though there's probably a lot more to it.

This is VERY incorrect, please read this :

http://www.faqts.com/knowledge_base/view.phtml/aid/1/fid/41
And then try this :
$name = 'fred';
echo "brb$name/bbr" . $name;
print "brb$name/bbr" . $name
Then try this :
echo 'sup','yo';
print 'sup','yo'; // Parse error!
But that FAQ explains it better then I can so ...
