พบโซลูชันที่ดีใน Zend Framework 2:

คลาสนี้อนุญาตให้คุณเริ่มต้นเฉพาะErrorHandlerบางครั้งหากคุณต้องการ จากนั้นคุณสามารถหยุด Handler ได้
ใช้คลาสนี้เช่นนี้:
ErrorHandler::start(E_WARNING);
$return = call_function_raises_E_WARNING();
if ($innerException = ErrorHandler::stop()) {
throw new Exception('Special Exception Text', 0, $innerException);
}
// or
ErrorHandler::stop(true); // directly throws an Exception;

ทางออกที่ดีกว่าอาจมาจากMonolog :

นอกจากนี้ยังสามารถจัดการ FATAL_ERRORS โดยใช้register_shutdown_functionฟังก์ชั่น ตามระดับนี้ FATAL_ERROR array(E_ERROR, E_PARSE, E_CORE_ERROR, E_COMPILE_ERROR, E_USER_ERROR)เป็นหนึ่งดังต่อไปนี้
class ErrorHandler
{
// [...]
public function registerExceptionHandler($level = null, $callPrevious = true)
{
$prev = set_exception_handler(array($this, 'handleException'));
$this->uncaughtExceptionLevel = $level;
if ($callPrevious && $prev) {
$this->previousExceptionHandler = $prev;
}
}
public function registerErrorHandler(array $levelMap = array(), $callPrevious = true, $errorTypes = -1)
{
$prev = set_error_handler(array($this, 'handleError'), $errorTypes);
$this->errorLevelMap = array_replace($this->defaultErrorLevelMap(), $levelMap);
if ($callPrevious) {
$this->previousErrorHandler = $prev ?: true;
}
}
public function registerFatalHandler($level = null, $reservedMemorySize = 20)
{
register_shutdown_function(array($this, 'handleFatalError'));
$this->reservedMemory = str_repeat(' ', 1024 * $reservedMemorySize);
$this->fatalLevel = $level;
}
// [...]
