PHP filename in sub-directory not allowed to be number w include

[Niss3]

Hello!

I am a beginner in PHP and made a simple quiz page. I named the quiz questions 1.php 2.php 3.php and so on to make coding simple when loading next question.

Now when I am done I wanted to "clean" things up. So I tried putting all the questions in a folder. That turned out to be a problem though.

When I use;

include(foldername\1.php);

The file is not loaded. It works fine if I put it back in the main directory.

After some error-searching I tried using letters instead of numbers, so I renamed 1.php to a.php and then suddenly it worked.

I really would like to keep the filenames as numbers, so if anyone here could help me figure out how to allow single digit number php files in a folder with the include command, please do!

Thank you very much!

Basically it's telling you that there rules to filenaming.

What's wrong with naming them 'page1.php' and 'page2.php'?  Too hard to program?

I didn't think of that, thanks! I did a quick test but it appears I have made some other misstake now. I will try again tomorrow and return here with the sollution I came up with, but I will definitly try to add a prefix to the files!

Actually what it's telling you is that \1 in a double-quoted string does something special...

[Niss3]

$filn=("f\aquick".$spelb);
include($filn.".php"); 

This is the sollution I came up with. Using include("path".$variable."filending") didnt work so I made some of it into a variable and it worked!

 

I have no idea what the double quote string thingy is. It did not accept "fraga" as filename either, so I guess it is complex when putting files in folders.

What is the backslash for?  What are the parens for?

//  determine what number to use in the name and assign it.
$i = GetNextFilNum();	// call a function that returns a number
$filename = "file$i.php";
include $filename;
