|Related to : require, require_once, include: which and why?|
|Using require_once then require|
I have two files A & B.
All the files are linked. In file A,
I have require_once(filename.php). In file B i have
require(filename.php). For some reason this causes some conflict when
running the code. There is code in File A that usually runs, but
doesnt when the above is the case. Any idea why? Thanks.
|auto prepend file versus require() or require_once()|
I'm using require_once() method, and I need to load a lot of files,
but depending by case, I load certain php file, not all at once. I'm
trying to speed up my application, and I'm wondering if I can put all
of them into php.ini file as auto prepend files.
Question : Does
auto prepend file do the same as requre() does?I'm speaking about
performances. Precisely, if I put
auto prepend file
auto prepend file /Files/file2.php
prepend file /Files/file3.php
auto prepend file
is it same as (time to get those files, or auto
prepend files add them on start of webserver)

|Difference between require_once(), require(), include() !|
Difference between require() and require_once(): require() includes
and evaluates a specific file, while require_once() does that only if
it has not been included before (on the same page). So, require_once()
is recommended to use when you want to include a file where you have a
lot of functions for example. This way you make sure you don't include
the file more times and you will not get the "function re-declared"
error. Difference between require() and include() is that require()
produces a FATAL ERROR if the file you want to include is not found,
while include() only produces a WARNING. There is also include_once()
which is the same as include(), but the difference between them is the
|Fatal error!: require_once() [function.require]:?|
what kind of error is this? my page was just running fine. i did
not change anything neither the location of the requested file.
