How can input data limits impact the execution of PHP scripts, especially during email sending tasks?

Input data limits can impact the execution of PHP scripts, especially during email sending tasks, by potentially causing errors or unexpected behavior if the input data exceeds the limits set in the PHP configuration. To solve this issue, you can adjust the PHP configuration settings related to input data limits, such as `post_max_size` and `upload_max_filesize`, to accommodate the expected data size for email sending tasks.

// Increase the input data limits for PHP
ini_set('post_max_size', '20M');
ini_set('upload_max_filesize', '20M');
