Get all PHP errors/warnings/… that occurred during the current request

Question

Setting the directive display_errors to true (while having error_reporting set to E_ALL) prints all errors that occured durin

Answer 1

Fuller example that catches all the errors (exceptions and errors), pumps to a log file and remembers in a static class; at the end you query the static class to get the error.

I use similar to this for all projects to get full control over all errors.

function customErrorHandler($errno, $errmsg, $filename, $linenum, $vars) {
    ErrorHandler($errno, $errmsg, $filename, $linenum, $vars, true);
}

function nullErrorHandler($errno, $errmsg, $filename, $linenum, $vars) {
    ErrorHandler($errno, $errmsg, $filename, $linenum, $vars, false);
}

function customExceptionHandler($exception) {
    if (is_a($exception, 'exceptionError')) {
        echo $exception->output();
    } else {
        ErrorHandler(E_ERROR, $exception->getMessage() . '(' . $exception->getCode() . ')', $exception->getFile(), $exception->getLine(), null, true);
    }
}

function nullExceptionHandler($exception) {
    if (is_subclass_of($exception, 'exceptionError')) {
        $exception->output();
    } else {
        ErrorHandler(E_WARNING, $exception->getMessage() . '(' . $exception->getCode() . ')', $exception->getFile(), $exception->getLine(), null, false);
    }
}


function ErrorHandler($errno, $errmsg, $filename, $linenum, $vars, $fatal) {
    $errortype = array (
            E_ERROR              => 'Error',
            E_WARNING            => 'Warning',
            E_PARSE              => 'Parsing Error',
            E_NOTICE             => 'Notice',
            E_CORE_ERROR         => 'Core Error',
            E_CORE_WARNING       => 'Core Warning',
            E_COMPILE_ERROR      => 'Compile Error',
            E_COMPILE_WARNING    => 'Compile Warning',
            E_DEPRECATED         => 'Deprecated',
            E_USER_ERROR         => 'User Error',
            E_USER_WARNING       => 'User Warning',
            E_USER_NOTICE        => 'User Notice',
            E_USER_DEPRECATED    => 'User Deprecated',
            E_STRICT             => 'Runtime Notice',
            E_RECOVERABLE_ERROR  => 'Catchable Fatal Error'
            );


    // Pushed into error log
    if (error_reporting() > 0) {
        $message = ': ' . $errmsg . ' in ' . $filename . ' on line ' . $linenum;
        error_log('PHP ' . $errortype[$errno] . $message);

        errorLogger::log($message);

        if ($fatal) {
            echo $errortype[$errno] . ': ' . $message;
            exit();
        }
    }
}


class errorLogger {

    private static $aErrors = array();

    // ******************* Timing functions *********************************

    public static function log($message) {
        self::$aErrors[] = $message;
    }

    public static function getErrors() {
        return self::$aErrors;
    }

}

Usage Example

// Custom error handler. Can cope with the various call mechanisms
$old_error_handler = set_error_handler('nullErrorHandler');
$old_exception_handler = set_exception_handler('nullExceptionHandler');

// Do your stuff
// *
// *
// *
// *
// *

$old_error_handler = set_error_handler('customErrorHandler');   // Set to 'nullErrorHandler' to allow it to continue
$old_exception_handler = set_exception_handler('customExceptionHandler');   // Set to 'nullExceptionHandler' to allow it to continue

// At end
$errors = errorLogger::getErrors();
foreach($errors as $errorMessage) {
    echo $errorMessage;
}
