使用php在Web服务器上写入文件

Question

I have an android app that should upload photo to web server using php and POST connection, I receive the photo String correctly but my problem is with saving it in the server.

the php file I am connecting on it is in the below location:

www.mysite.com/project/code.php.

PHP is enabled on my website, and I enabled fopen command

I also tried to open any file and write anything in it but I fail (Echo doesn't executed and no file is saved). what is the problem? should I have special permissions to be able to create files?

Code:

?php
// Get image string posted from Android App
$base=$_REQUEST['image'];
// Get file name posted from Android App
$filename = $_REQUEST['filename'];
// Decode Image
$binary=base64_decode($base);
header('Content-Type: bitmap; charset=utf-8');
$file = fopen('uploadedimages/'.$filename, 'wb');
// Create File
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete, Please check your php file directory';
?>

Answer 1

Check your Apache (or equivalent) logs to see if it is a permissions issue. If it is, you can set the owner of the folder to Apache from the linux command line with sudo chown www-data:www-data /uploadedimages/ and give owner-write permissions with chmod 0744 /uploadedimages/ . That command also gives global and group read permissions, so you should double check if that is suitable.
