How can the open_basedir restriction error be resolved when specifying file paths for uploads in PHP?

The open_basedir restriction error in PHP occurs when the specified file path for uploads is outside the allowed directories defined by the open_basedir directive in the php.ini file. To resolve this error, you can either adjust the open_basedir directive in the php.ini file to include the desired upload directory or move the upload directory to a location within the allowed directories.

ini_set('open_basedir', '/path/to/allowed/directory');
