require_once 'PEAR.php'; require_once 'MyPackage.php'; // set a custom error handler for MyPackage function myErrorHandler($error) { // log the error error_log($error); } PEAR::pushErrorHandling('myErrorHandler', PEAR_ERROR_CALLBACK); // use MyPackage $myPackage = new MyPackage(); $myPackage->doSomething(); PEAR::popErrorHandling();
require_once 'PEAR.php'; // set a custom error handler for all PEAR packages function myErrorHandler($error) { // log the error error_log($error); } PEAR::pushErrorHandling('myErrorHandler', PEAR_ERROR_CALLBACK); // use PEAR package PEAR::raiseError('An error occurred'); PEAR::popErrorHandling();In both examples, we are setting a custom error handler function `myErrorHandler` and passing it to the `PEAR::pushErrorHandling` function. The second parameter, `PEAR_ERROR_CALLBACK`, specifies that the first parameter is a callback function. We then use the package/library and when an error occurs, our custom error handler function is called. Overall, PEAR is a package library for PHP that provides reusable code and solutions to commonly found problems for developers.
