Question

I am working in php on ubuntu. When I use any image on web page which has denied access, there is warning on page. I want to check it before displaying and if it does not have rights to open then give it access to open. As we do in terminal command.

chmod 777 myimage.jpg

How to check this and give full access to a file in php.

Thanks

Check the function is_readable() and is_writable().

Example:

$filename = '/home/myuser/example.txt';

if (is_readable($filename) && is_writable($filename))
{
    echo "File has read and write permissions.";
}
