J'ai téléchargé la dernière version de symfony sur le site officiel : https://symfony.com/

tout s'est bien passé mais j'ai du mal à l'installer.Je précise qu'il s'agit d'une installation sans passer par composer.
J'ai créé un repertoire de mon projet et je suis sur windows 8.1 et Wampserver fonctionne correctement .Je précise que ma version de php est 5.5.12.
Je précise que j'ai installé le tout dans un répertoire qui porte le nom de symfony.
Seulement, quand je lance l'adresse : http://localhost/Symfony/web/config.php j'obtiens une page blanche avec le contenu ci-dessus :

Configuration Checker

This script analyzes your system to check whether is ready to run Symfony applications.
Recommendations

To enhance your Symfony experience, it’s recommended that you fix the following:

1 Set "xdebug.max_nesting_level" to e.g. "250" in php.ini* to stop Xdebug's infinite recursion protection erroneously throwing a fatal error in your project.
2 In most cases you should be fine, but please verify there is no inconsistencies between data provided by Symfony and the intl extension. See https://github.com/symfony/symfony/issues/15007 for an example of inconsistencies you might run into.
3 Install and/or enable a PHP accelerator (highly recommended).

* Changes to the php.ini file must be done in "C:\wamp\bin\apache\apache2.4.9\bin\php.ini".

Je ne trouve pas le : xdebug.max_nesting_level, dans mon php.ini, comment faire?




et lorsque je lance cette adresse : http://localhost/symfony/web/app_dev.php/

j'obtiens :

Whoops, looks like something went wrong.

Comment le résoudre?
Merci d'avance pour ceux qui voudront m'aider car depuis quelques jours je galère et je ne sais pas comment faire...
dsl si j'ai posté un long message ,mais c'est dans le but de mettre toutes les infos pour avoir une aide complete

Bjr, tu as déjà un problème dans C:\wamp\www\symfony\app/config\parameters.yml
vérifie bien la structure du fichier et si l erreur s'affiche encore ,partage nous son contenu.

[adamsid2000]

Mon fichier parameteres.yml contient exactement tout ce qui est en bleu,que dois je faire alors?


# This file is a "template" of what your parameters.yml file should look like
#
Set parameters here that may be different on each deployment target of the app,
e.g. development, staging, production.

# http://symfony.com/doc/current/best_...iguration.html
#infrastructure-related-configuration
parameters:

database_host: 127.0.0.1
database_port: ~

database_name: symfony
database_user: ~

database_password: null

# You should uncomment this if you want use pdo_sqlite

# database_path: "%kernel.root_dir%/data.db3"

mailer_transport: smtp

mailer_host: 127.0.0.1
mailer_user: ~
mailer_password: ~

# A secret key that's used to generate certain security-related tokens
secret: ThisTokenIsNotSoSecretChangeIt

[MehrezLabidi]

ok, appart la ligne "parameters" ,tous les autres doivent être précédés par 4 espaces.
si tu veux tu peux créer un nouveau projet symfony2 pour voir la bonne structure par défaut pour ce fichier.

[adamsid2000]

j'ai rajouté 4espaces devant chaque ligne, ça ne fonctionne toujours pas..........
