How can file permissions and access rights impact the functionality of PHP scripts, particularly in cases where required files are missing?

File permissions and access rights can impact the functionality of PHP scripts by preventing the script from accessing required files. This can result in errors or incomplete functionality if the script is unable to read or write to the necessary files. To solve this issue, you can ensure that the files have the correct permissions set to allow the PHP script to access them. 

// Ensure the file has the correct permissions set
chmod("path/to/file.txt", 0644);
