Are there any best practices for handling PHP scripts that need to differentiate between command line and user interaction?

When working with PHP scripts that need to differentiate between command line and user interaction, a common approach is to check the PHP_SAPI constant to determine the current interface. For command line scripts, PHP_SAPI will be set to "cli", while for web-based scripts, it will typically be set to "cgi" or "apache". By checking this constant, you can easily branch your code logic to handle the different scenarios accordingly. 

if (PHP_SAPI === 'cli') {
    // Code for command line interface
    echo "Running in command line mode\n";
} else {
    // Code for web-based interface
    echo "Running in web mode\n";
}
