What is the open_basedir restriction in PHP and how does it affect file uploads?

The open_basedir restriction in PHP is a security measure that limits the files that PHP can access to a specific directory or directories. This restriction can affect file uploads if the directory where the uploaded files are stored is outside the allowed paths specified in the open_basedir directive. To solve this issue, you can either adjust the open_basedir directive to include the directory where the uploaded files are stored or move the uploaded files to a directory within the allowed paths.

// Adjust open_basedir directive to include the directory where uploaded files are stored
ini_set('open_basedir', '/path/to/allowed/directory:/path/to/uploaded/files/directory');
