How can file permissions and user rights impact the functionality of the "glob" function in PHP?

File permissions and user rights can impact the functionality of the "glob" function in PHP if the user running the PHP script does not have sufficient permissions to access the files or directories specified in the function. To solve this issue, ensure that the user running the PHP script has the necessary permissions to read the files and directories being accessed by the "glob" function. 

// Set appropriate permissions for the files and directories
// Make sure the user running the PHP script has read permissions

$files = glob('/path/to/files/*.txt');

foreach ($files as $file) {
    // Process each file
}
