What are some common issues with PHP scripts when executed through scheduled tasks compared to browser execution?

One common issue with PHP scripts executed through scheduled tasks is that the environment variables may not be set correctly, leading to errors. To solve this, you can explicitly set the necessary environment variables within your PHP script. 

// Set necessary environment variables for scheduled task execution
putenv('DB_HOST=localhost');
putenv('DB_USER=username');
putenv('DB_PASS=password');

// Your PHP script code here
// Example:
$pdo = new PDO('mysql:host=' . getenv('DB_HOST') . ';dbname=mydatabase', getenv('DB_USER'), getenv('DB_PASS'));
