Save a file in a folder using file_put_contents PHP

Question

I have a simple PHP that will save a file to a specific folder. I already change the permission in 777 but I'm getting errors:

Warning: file_put_contents(/var/www/html/foldername/): failed to open stream: Is a directory on line 22
Warning: chmod(): Operation not permitted on line 23

How to fix these?

PHP

$file_name = '';
$file_binary = '';

$folder = "foldername";
$file_name = isset($_POST['file_name']) ? $_POST['file_name'] : '';
$file_binary = isset($_POST['file']) ? $_POST['file'] : '';
$file_directory = "/var/www/html/foldername/".$file_name;
file_put_contents($file_directory,str_replace("\\","",$file_binary));
chmod($file_directory,0777);

Are you sure, `"/path/foldername/".$file_name` is a valid path ? Never set permission to 777, 644 will be sufficient for files and 755 for folders. — Gaurav, Sep 27 '16 at 05:09

When there is a fileupload, you should get the data with $_FILE, not with $_POST. Try to change your code.

I think there are few correction need to be done in your code. first please add a default file name into your ternary operator, and instead of using file_put_content use fopen along with 'r+' please check the url for more options, and before creting a file need to check directory exist and is writable. Hope this will help you.

the directory is writable, i double checked the folder permission. – User014019 Sep 27 '16 at 06:08
check through the code it may be happen sometime like php user is different and we are checking from another user. – Ashish Ranade Sep 27 '16 at 06:13
i already use the fopen, but still i'm getting same error in `file_put_contents` – User014019 Sep 27 '16 at 06:29
Have you use both fopen and file_put_content at the same time, I saw your error message it looks like file name is missing in as parameter "Warning: file_put_contents(/var/www/html/foldername/):". – Ashish Ranade Sep 27 '16 at 06:34
no i didn't use both at the same time, i comment the `file_put_contents` – User014019 Sep 27 '16 at 06:37

Try this,

$file_name = '';
$file_binary = '';

$folder = "foldername";
$file_name = isset($_POST['file_name']) ? $_POST['file_name'] : '';
$file_binary = isset($_POST['file']) ? $_POST['file'] : '';
//to create directory:

$folderPath = "/var/www/html/foldername";

is_dir($folderPath) || @mkdir($folderPath) || die("Can't Create folder");

$file_directory = "/var/www/html/foldername/".$file_name;
file_put_contents($file_directory,str_replace("\\","",$file_binary));
chmod($file_directory,0777);
