Question

How to rename file with name containing "/", in PHP example : "A / B"

$filename= "A / B";
rename("1.html", $filename.".html"); 

doesn't work!

Answer 1

On linux machines and on OSX, the forward slash (/) is a forbidden character. The file system will not let you use this character in a filename.

Answer 2

I try it and it is possible to modify the string, but as the other users say... it is possible/you will run into a problem with your OS. Becouse the / caracter is used by tree of the OS.

/                 --> is root
/folderX          --> is the folde X in the root folder
/folderX/yourFile --> is the file in the folderX in the root folder

This is the code I run on the website

<?php
$filename = "this/is/a/test";

$filename = str_replace("/", "-", $filename);
var_dump($filename)

?>

And this is the result

string(14) "this-is-a-test"

As you see this is a path to a file called test this/is/a/test

And this a filename without a path this-is-a-test

I hope this answer helps you to see the difference.
