Perhaps the manual should be made to reflect this since, my understanding came from the online version of the manual. Sterling Philip Olson wrote: Yes, this is essentially true.

[PHP] Re: include_once vs require_once
Did you look at the difference between include() and require()? Basically, as I understand it, require() and require_once() are replaced during parsing--before code execution. And include() and include_once() are replaced during code execution. Thus, a required file is always imported into the file whereas an included file is only imported if the include() statement is executed. The same is true for the _once() versions except that the statement evaluates to nothing if the file has already been imported by another statement.

Re: [PHP] Re: include_once vs require_once
cool, so the difference is _when_ they happen. ok, another question then. if my script includes the line require_once($file); and $file contains the line include_once($other_file); what happens then? :) thanks, mike on 7/31/01 6:57 PM, Andrew Sterling Hanenkamp at [EMAIL PROTECTED] wrote: Did you look at the difference between include() and require()?
