create folder in php using a variable in path

Question

i am a newbie in the field of web development, i am trying to create a folder using php's mkdir() command...

when i use...

mkdir("somefolder");

it works...

i had tried

mkdir("/somefolder/".$id."/photos");

but it won't work....i think i am doing it wrong how do i do this...

well the $id is coming from the database so that folder for each user will be created

Any help will be greatly appriciated...

thank you in advance...

EDIT

mkdir($id);

does creates a folder but above mentioned doesn't....

if somefolder is already there.. then mkdir won't work....?

for this purpose recursive parameter needs to be true...

mkdir("/somefolder/$id/photos",0777,true)

$path = "/somefolder/$id/photos";

if (!file_exists( $path ) mkdir($path);

else

throw new Exception($path." file already exist");

Remove the single quotes around $id

mkdir("/somefolder/$id/photos");

This line is incorrect:

mkdir("/somefolder/'$id'/photos");

Instead it should be

mkdir("/somefolder/".$id."/photos");

or

mkdir("/somefolder/$id/photos");

Make sure that your www-data user (or whichever user your script runs under) has the rights to create folders in /somefolder (chown www-data /somefolder)

and please remember to check that $id has the correct format before to avoid access to other directories with $id = "../.."

You could use

if(!is_numeric($id)) {
    /* do something */
}

thanks for your reply Eric, if $id is numeric... then is it possible to create folder...

David Over a year ago

if it doesn't work give the rights to the www-data user or which ever user your server runs under. chown www-data /somefolder/

Maybe it's a problem with your absolute/relative path. Try removing the first slash. mkdir("somefolder/$id/photos")
