What are common permission issues that can cause PHP errors when uploading a website to a web server?

Common permission issues that can cause PHP errors when uploading a website to a web server include incorrect file or directory permissions, which can prevent PHP scripts from reading or writing files. To solve this issue, you can adjust the permissions of the files and directories to ensure that PHP has the necessary access.

// Set the correct permissions for files and directories
chmod("path/to/file.php", 0644); // Set read permissions for files
chmod("path/to/directory", 0755); // Set read and execute permissions for directories
