What are some common error codes that can occur when using the symlink function in PHP?

One common error code that can occur when using the symlink function in PHP is "Permission denied." This error typically means that the user running the PHP script does not have the necessary permissions to create the symlink in the specified directory. To solve this issue, you can either change the permissions of the directory or run the PHP script as a user with the appropriate permissions.
