RE: [PHP] require or include ?
require() is used when you want the file included regardless of whether any information is used from it. include() may be conditional. -Original Message- From: javier [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 28, 2002 4:44 PM To: [EMAIL PROTECTED] Subject: [PHP] require or include ? When should I use require or include? I read that include copies the content from the file to the script that is calling it.

Re: [PHP] require or include ?
If I include for ex. common.php in a script and this script also calls common.php what should I use require or include?

Re: [PHP] require or include ?
both include the file, but use require() when it is required, and include() when it's not. In the new behaviour these two make no further difference. bvr.

RE: [PHP] require() vs include()
-Original Message- From: Jim Lucas [php] [mailto:[EMAIL PROTECTED]] Sent: 15 March 2002 00:55 Plus, depending on how you are calling the file. Meaning if the file name that you are calling is a static file name or dynamic file name require() and require_once() will include a file before the php parser starts its job, but this will only happen if the name isn't dynamic. In fact, I believe that what you are describing is an OLD behaviour (prior to PHP 4.0.2, in fact). However, the manual has only recently changed to document the new behaviour (and actually doesn't do it very well, yet). Now, BOTH require and include (and their _once versions) work dynamically, and the only difference is in how they report a failure. Cheers!

RE: [PHP] require() vs include()
They are much the same, both include a file. To quote the PHP manual require() and include() are identical in every way except how they handle failure. include() produces a Warning while require() results in a Fatal Error. In other words, don't hesitate to use require() if you want a missing file to halt processing of the page. include() does not behave this way, the script will continue regardless. Be sure to have an appropriate include_path setting as well. That said I would use require_once and include_once instead of just include and require, these functions ensure the file is only included once which prevents a lot of problems.

Meaning if the file name that you are calling is a static file name or dynamic file name require() and require_once() will include a file before the php parser starts its job, but this will only happen if the name isn't dynamic. meaning that if you have this require(myfile.inc); //static and require($var. .inc); //dynamic the first one will be included into the before parsing and the second will wait until the parser comes along and defines the $var value. if you call require() or require_once() with a variable in the file handler name space, it will downgrade (in a way) to just working like an include() or include_once() with include() or include_once() it doesn't matter if the file handle name has a variable in it. it will always include the file after the parser starts its job.

Re: [PHP] require or include
It all depends on the purpose.
With require, the script will die on the spot if the file is not found.
Also, the code will always be included in the file.. so take this example:
file.php:
?
echo Hello World!;
?
requiretest.php:
?
if (FALSE) {
require('file.php');
}
?
The run script would be:
?
if (FALSE) {
echo Hello World!;
}
?
Of course that code would never be executed, but the required file would
be parsed and included as part of the file, whereas:
includetest.php:
?
if (FALSE) {
include('file.php');
}
?
If the if() condition is not met, the file is not included at all.. so
the parsed code would be:
?
if (FALSE) {
}
?
:)
