RE: [PHP] Require() vs Include()

If include() fails the return value is false. Andi At 21:22 13/11/00 -0800, jeremy brand wrote:

How can you not allow it to fail? if you go to require('/tmp/the_file_that_does_not_exist'), how do you handle that successfully and still finish the script? This is the claim that Joe and I's co-worker claimed. Above was my example back to him. That was the end of the conversation. I do understand what you are saying, but it is misleading when you say it is not allowed to fail -- it implies (apparently to our co-worker) that even if a file doesn't exist, somehow his code was magically going to work anyway. This seems to be what is probably most misunderstood. -jeremy brand http://www.JeremyBrand.com/Jeremy/Brand/Jeremy_Brand.html for more --------------------------------------------------------------------- We cannot do everything at once, but we can do something at once.

Subject: RE: [PHP] Require() vs Include() In the latest versions of PHP 4.0 (I think since 4.0.2) require() and include() behave exactly the same *except* that a require() is not allowed to fail. So feel free to use any of these two, they are the same speed. The implementation of require() used to be different but both for consistency reasons and due to the fact that the old require() wasn't faster than the include() as it was supposed to be we chose consistency.

Hi Maxim, Suppose you have this: --file1.php-- <?php print("\nin file1.php"); ?> --file2.php-- <?php print("\nin file2.php"); ?> Now, suppose you want to include certain files, based on conditions: --test.php-- if($myCatVioletHasBlackFur == "no")

        require(file1.php);

if($myCatVioletHasBlackFur == "yes")

        include(file2.php);

Well, my cat, Violet <g>, has black fur, so the 2nd condition is

valid, the

1st is false. However, require() is executed regardless, so, the output of test.php is: in file1.php in file2.php So, what if I change test.php to: --test.php-- if($myCatVioletHasBlackFur == "no")

        include(file1.php);

if($myCatVioletHasBlackFur == "yes")

        include(file2.php);

Well, Violet still has black fur, so, the output is: in file2.php Hope this helps. =) marco -----Original Message----- From: Maxim Maletsky [mailto:maxim.maletsky@japaninc.net] Sent: Monday, November 13, 2000 9:21 PM To: 'PHP General List. (E-mail)' Subject: [PHP] Require() vs Include() Hi, A tiny question: why to use require() when include() works just as well and even better

when

there are some conditions like if{} ? I ask it because although I read many articles on this issue I found no reason for myself to use require() instead of include() and I have driven some huge projects in PHP. Why do I see these hardcore PHP gurus writing PHPLIB, mySQLadmin and examples in their articles using require() where include() would fit

just as

perfect? WHERE THE TRIIIICK? It escapes from me ... Thanks. Maxim Maletsky - maxim@j-door.com <mailto:maxim@j-door.com> Webmaster, J-Door.com / J@pan Inc. LINC Media, Inc.
