require

Have I read the manual entry? Oh, yes. I'm doing some writing on PHP and am attempting to show an example of when require will not work as one would like. The manual says: "This means that you can't put a require() statement inside of a loop structure and expect it to include the contents of a different file on each iteration." However, in writing an example like the following, require did include all five files... $i = 0 while ($i < 5) { $filename = "myfile_$i.php" require $filename; $i++; } Someone else suggested to me that the contents of a require will not be re-evaluated within a loop. However, the following two files printed all numbers from 0-10. #file1 <? $i =0; while ($i <=10) { require "file2.php"; $i++ } ?> #file2.php <? echo $i; ?> So I guess I have 2 questions: First, can someone give me an example, using PHP 4.0.2, where require behaves differently from include? Secondly, I'm wondering if the differences between include and require are a big issue for many of you. I put my includes at the top of the page, one at the bottom, and I'm set. Thanks much, jay
