FatalErrorException：输入字符串太长

I've started to build a new Laravel 5 app. I need a site message feature in my app, so I created one. But now when I'm trying to add messages into stack, I'll get the following error:

FatalErrorException in ExceptionHandler.php line 412: Input string is too long

Apache error log says:

Mon Mar 28 20:25:40.310761 2016] [fcgid:warn] [pid 2075:tid 3028430848] [client 127.0.0.1:56643] mod_fcgid: stderr: PHP Fatal error: Input string is too long in /Users/xxx/Development/Laravel/myapp/vendor/symfony/debug/ExceptionHandler.php on line 412, referer: http://app.dev/page/new

I call Message::set method in my controller:

Message::set('Page created');

And the Message class contains:

<?php

namespace App\Models;

use Session;

class Message {

    const MESSAGE_INFO      = 0x1;
    const MESSAGE_WARNING   = 0x2;
    const MESSAGE_ERROR     = 0x3;

    public static function set($message, $type = MESSAGE_INFO) {
        $messages = self::get(false);
        $messages[$type][] = $message;

        Session::put('app.messages', $messages);
    }

    public static function get($flush = true) {
        $default = [ self::MESSAGE_INFO => [], self::MESSAGE_WARNING => [], self::MESSAGE_ERROR => []];

        if($flush) Session::pull('app.messages', $default);
        return Session::get('app.messages', $default);
    }

    public static function isAny() {
        $messages = self::get(false);

        foreach($messages AS $store) if(!empty($store)) return true;

        return false;
    }

}

I'm so lost with this. Can someone help me with this?

Might be wrong, but I'm not sure you can store an array in a Laravel session.

After you store that array in the session

Session::put('app.messages', $messages);

try to dump your session variable:

dd(Session::get('app.messages'));

Come back with the result you get so we can dig deeper. Good luck!

Problem was with this line:

public static function set($message, $type = MESSAGE_INFO) {

It should be:

public static function set($message, $type = self::MESSAGE_INFO) {

MESSAGE_INFO constant is defined in the Message class, not globally.

The error message was really confusing. When I put the Message::set('Page created'); call inside a try-catch block, then error message was:

FatalErrorException in GroupManagementController.php line 45: Allowed memory size of 268435456 bytes exhausted (tried to allocate 2890768384 bytes)
