require_once 'PEAR.php'; require_once 'popErrorHandling.php'; // Configure error handling popErrorHandling::setLogFile('/path/to/logfile.txt'); popErrorHandling::setLevel(PEAR_ERROR_TRIGGER); // Trigger an error trigger_error('An error occurred', E_USER_ERROR); // Display errors popErrorHandling::showErrors();In this example, we first include the PEAR.php and popErrorHandling.php files in our PHP code. We then configure the error handling settings using the setLogFile and setLevel functions. These functions specify the location of the error log file and the level of errors that should be displayed. In this case, we are only displaying errors that have a severity level of PEAR_ERROR_TRIGGER or higher. We then trigger an error using the trigger_error function, which simulates an error occurring during program execution. Finally, we use the showErrors function to display any errors that were generated during code execution. Based on the name and description, it is likely that the popErrorHandling package is a library for managing errors that occur during PHP code execution.
