How can PHP be configured to call a specific function when errors, notices, or warnings occur during script execution?

To configure PHP to call a specific function when errors, notices, or warnings occur during script execution, you can use the set_error_handler() function. This function allows you to define a custom error handling function that will be called whenever an error occurs. Within this custom function, you can handle the error in any way you see fit, such as logging it to a file or displaying a custom error message. 

```php
function customErrorHandler($errno, $errstr, $errfile, $errline) {
    // Handle the error as needed, such as logging it to a file
    error_log("Error: $errstr in $errfile on line $errline");
}

set_error_handler("customErrorHandler");
```

In this code snippet, we define a customErrorHandler function that logs the error message, file, and line number to a file using the error_log() function. We then use set_error_handler() to set this custom function as the error handler for PHP. Now, whenever an error occurs during script execution, our customErrorHandler function will be called to handle it.
