require_once 'PEAR.php'; // Define a custom error handler function function myErrorHandler($error) { // Do something with the error echo "Error: $error"; } // Set custom error handling for package MyPackage PEAR::setErrorHandling('myErrorHandler', PEAR_ERROR_CALLBACK);
require_once 'PEAR.php'; require_once 'MDB2.php'; // Define a custom error handler function function myErrorHandler($error) { // Do something with the error echo "Error: $error"; } // Set custom error handling for MDB2 package MDB2::setErrorHandling('myErrorHandler', PEAR_ERROR_CALLBACK);In this example, we require both the PEAR library and the MDB2 database library. We define a custom error handler function called `myErrorHandler()` and set it as the error handler for the MDB2 package using the `setErrorHandling()` method. In both examples, we are using the PEAR library's `setErrorHandling()` method to set a custom error handler function for a particular package or module. This method takes two arguments: the name of the error handler function and the type of error handling to use (in these examples, we use `PEAR_ERROR_CALLBACK` to specify a callback function). From the examples, we can determine that the `setErrorHandling()` method is part of the PEAR library, which is a PHP package management system that provides a collection of reusable PHP components.
