Delete file created with php script from php -

-

i have script creates, updates or delete file given argument on /var/www/ folder.

if( $_server['request_method'] === 'put' ){             $params = json_decode(file_get_contents("php://input"));             $myfile = fopen( '/var/www/folder/'. $params->name , "w") or die('failed open file'. $params['name']);             fwrite( $myfile, $params->command );             fclose();     } else if( $_server['request_method'] === 'delete' ){             $params = json_decode(file_get_contents("php://input"));             echo unlink( '/var/www/folder/'. $params->name )? "the file deleted" : "the file not deleted". '\n';     }

i having issue, though. files being succesfully created in folder, aren't being deleted unlink command - returns false.

the apache server running on ubuntu machine. 'folder' permissions 777 , permissions script.

files created inside folder of user:group www-data. permissions default permissions.

any ideas on why script can't delete files has created itself?
