When I wrapped it like this:

$months = array(1 = 'January', 2 = 'February', 3 = 'March', 4

7 = 'July', 8 = 'August', 9 = 'September', 10 =

return $months;
}
it worked. Not sure why the simple variable didn't work.

Was the $months variable created inside an if statement or something
else? PHP's rules of scope say that variables created inside a code
block (like an if, a for, a while, a foreach), they stop existing the
moment you exit that code block. So this:
$foo = bar;
if ( $foo == bar )
{
$baz = narf;
}
echo $baz;
That code will output nothing, because $baz is empty by the time I try
to output it. The solution that I use is this:
$foo = bar;
$baz = ;
if ( $foo == bar )
{
$baz = narf;
}
echo $baz;
In which case the output would be narf, because the variable existed
before I changed it in the if. This sounds like it might be your
problem, though I can't know without seeing the code.

That's wrong sorry :)
$ php -a
Interactive mode enabled
?php
$foo = bar;
if ( $foo == bar )
{
$baz = narf;
}
echo $baz;
narf
Works fine.
If you only create the variable inside the if you won't be able to use
it if the code doesn't get into the if (it'll be an undefined variable):
$ php -a
Interactive mode enabled
?php
error_reporting(E_ALL);
if (1 == 0) {
$foo = blah;
}
echo $foo;
Notice: Undefined variable: foo in - on line 6

Thanks Torsten! Using the file-system relative path made it work (I had tried only with the absolute path, which ddidn't work). However, I checked again and I did have 'allow_url_fopen = On' in /etc/php.ini. I'll take a closer look later and report the problem if I find it.

Hi,
I'm almost ashamed to ask this question as surely enough the
problem is something very basic but, nonetheless, I can't put my finger on
it. I'm trying to implement the concept of a library (library.php) on PHP
where I define (once) all auxiliary functions and then use them in a file
(for instance index.php) via the 'require' or 'include' constructs. Here's
a
reduced version of what I'm doing:
index.php:
?php
$lang = (isset($_REQUEST['lang']) ? $_REQUEST['lang'] : es);
echo index.php: include_path is . (ini_get('include_path')).br;
require(http://tristan/library.php?lang=$lang;);
my_function(en);
?
library.php:
?php
echo library.php: Called with $_SERVER[HTTP_HOST]:/$_SERVER[REQUEST_URI]
br;
function my_function($lang = es) {
echo my_function() says $lang;
}
echo library.php: loadedbr;
?
When I load index.php I get the following:
index.php: include_path is .:/usr/local/php/4.3.6/lib/php
library.php: Called with tristan://library.php?lang=es
library.php: loaded
Fatal error: Call to undefined function: my_function() in
/www/htdocs/index.php on line 5
It seems that the name space on index.php never gets updated
with the function definitions made on library.php. What am I doing wrong?
Thanks! Cheers,
Daniel
Hi Daniel,
take a look at this section of the manual about including remote files:
If URL fopen wrappers are enabled in PHP (which they are in the default
configuration), you can specify the file to be included using a URL (via
HTTP or other supported wrapper - see Appendix J for a list of protocols)
instead of a local pathname. If the target server interprets the target file
as PHP code, variables may be passed to the included file using a URL
request string as used with HTTP GET. This is not strictly speaking the same
thing as including the file and having it inherit the parent file's variable
scope; the script is actually being run on the remote server and the result
is then being included into the local script.
Try including it as a local file:
require_once library.php'; // if it is in the same directory as the file you
have this line in
Also you don't have to pass $lang via Get to the file as the included code
will have access to $lang as it is then in the scope of the script.
Regards, Torsten

[PHP] Re: include() and require() problem
be sure that the path to the include file is relative to the script that was requested by the user. that's important if you include include-files into included files. you then have to make sure that the path to your include-file in the include-file is relative to the file that included the file, in which the include-file is included. *lol* what a sentence. anyway, hope you get my meaning! another problem is using include /myincfiles/myfile.inc; this way it could be searched in the root of the server, where for sure your file can't be found. use relative path instead: include ./myincfiles/myfile.inc; ./ means the same directory. or use an absolute path, which has to contain the whole path from the server's root, e.g.: include /wwwroot/somedir/yourdocroot/myincfiles/myfile.inc; Regards Michael Rodrigo Peres [EMAIL PROTECTED] schrieb im Newsbeitrag [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... List, I'm trying to include some .inc files in my project, but I got errors all time saying that this includes couldn't be found. I'm a newbie, so I can't understand what's happend, since it worked pretty good in my local machine and not in the ISP. I tried to speak to ISP many times but they couldn't solve to. My directorie structure is : HRM(directorie)-includes(directorie)-my inc files(to be included in files that is in the directorie HRM).

I'm also having a problem with including file into and include file.
