require() and include()? which's faster?

[Anon]

hello!

I have a question. Aside functional differences between require() and include(), is there any performace differences? And if so, which one is faster if including the same file?

thank you.

include() CAN be faster.

Consider

//fileA.php

if (1==2)
include("apieceofcode.inc.php")
else
include("somethingelse.inc.php")

//fileB.php

if (1==2)
require("apieceofcode.inc.php")
else
require("somethingelse.inc.php")

In this case fileA.php is faster because it contains less code I think. (because it means less work for php.exe)
The two functions do pretty much the same thing, and I think that the name difference is there instead of parameters.

Alex, Peter -
include essentially is faster than require, but not solely for the reasons Peter mentioned. Require drops out of the PHP parser and processes the file as text/html before running through and parsing the php code again, which is why you have to have your <?php ?> delimiters in a require()'d file. include() assumes that the file is pure php. It never stops to process HTML, and therefor will be quicker - provided you don't have any html in the file.
