What are the common pitfalls in logging PHP errors when scripts are executed by external programs?

Common pitfalls in logging PHP errors when scripts are executed by external programs include not setting up proper error handling mechanisms within the PHP script itself, not specifying the correct path for the error log file, and not checking for permissions issues that may prevent the script from writing to the log file. 

// Set up error handling mechanism
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Check if the error log file is writable
if (!is_writable('/path/to/error.log')) {
    die('Error log file is not writable');
}

// Your PHP script code goes here
