Bug #14165 Updated: No way to return variables from remote include()

ID: 14165 User updated by: steve@petabit.com Reported By: steve@petabit.com Status: Bogus Bug Type: Feature/Change Request Operating System: Linux PHP Version: 4.0.5 New Comment: Dear Brian, Marco et al: Sorry to be persistent, but I am pretty sure that my postings have been misunderstood, and the last reply I just got from Marco confirms it. I'm hoping once you understand the question, the "bogus" nature of the question will go away. According to the php "include()" manual, and in my own experience, it is perfectly valid to request that a remote file be executed as php, using include() or require(). One need only compile using "URL fopen wrappers": (manual quotes in [[[ ]]]) [[[If "URL fopen wrappers" are enabled in PHP (which they are in the default configuration), you can specify the file to be include() ed using an URL instead of a local pathname. See Remote files and fopen() for more information. ]]] It is also possible to pass variables to the include()ed file: [[[ If the require() ed file is called via HTTP using the fopen wrappers, and if the target server interprets the target file as PHP code, variables may be passed to the require() ed file using an URL request string as used with HTTP GET. This is not strictly speaking the same thing as require() ing 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. ]]] SO: The missing feature/doc is: How do I get the require()ed file to pass back some string information? I can't use the HTTP GET-style request string, or even the return() function within an include() (because it only returns an integer). I don't think this is a bogus request, it seems to me to be a logical extension of the URL request idea. If it's currently impossible, I'm looking for a workaround. Marco's suggestion to print out the database using cvs doesn't change anything, since I still can't pass a string back. Best regards, Steve Rapaport.

If you need content from a database so print's it as csv and use the output in your script. http://www.php.net/csv -- Marco Btw. Ask this type of question on the general or dev mailing list. ------------------------------------------------------------------------ [2001-11-21 15:47:59] steve@petabit.com This is not the same as 14164. Thanks for the quick response, Brian. I appreciate that the remote file is parsed remotely, and so the var spaces are on different machines. Here's a rephrase of 14165: Given that it *is* possible to pass variable values to a remotely INCLUDE()d file using GET-style syntax, HOW DOES ONE GET ANYTHING BACK? Include appears only to return a single integer, at best. The remotely included file is calling a database and retrieving values. How does the calling file access them? ------------------------------------------------------------------------ [2001-11-21 14:46:07] brianlmoon@php.net Please do not ask the same question twice in the bug system. ------------------------------------------------------------------------ [2001-11-21 14:38:39] steve@petabit.com Related to bug 14164: All workarounds I have tried to pass variable data back from a remotely include()d or require()d script have failed. Arrays and strings don't appear to be passed back in the include()'s return value, it will only pass back integers. If anyone sees another way to do this please help! I will keep looking and post a followup here and to the manual if I find a workaround.
