使用php在Linux中读取图像文件

Question

I have created an image file like this

$imageData = file_get_contents($_POST['imgs1']);
chmod('/var/www/r1/assets/admin/pages/chart/image2.png',0644);
file_put_contents('/var/www/r1/assets/admin/pages/chart/image2.png',$imageData);

Now the problem is file is created with lock symbol. How can I remove this lock symbol from file using php?

Answer 1

The lock symbol in Linux is because you don t have write permission to the file. in this case,file permission is 644 and the owner is user apache.then you don t have write permission to the file. in this case,file permission is 644 and the owner is user apache.then you don t have write permission.

For removing the lock icon, change the permission to 755 or change the owner of the file to your user (I recommend changing chmod ).

chmod('/var/www/r1/assets/admin/pages/chart/image2.png',0755);

Answer 2

Lock symbol means you don't have permission on that image.To remove lock symbol you have to give right permission 777

use

exec("chmod -R 777 /var/www/r1/assets/admin/pages/chart/image2.png");
