logs avec php

Bonjours;

j'ai decider de créer un code Php permettant de faire des logs et de les insérer dans une bd mais cela ne marche pas et n'affiche aucune erreure mais l'entrée n'est pas créée.

<?php
include("sql.php");
if(1)
{
        $req = $bdd->prepare('INSERT INTO historiquedetoutesconnexions(GATEWAY_INTERFACE, SERVER_ADDR, SERVER_NAME, SERVER_SOFTWARE, SERVER_PROTOCOL, REQUEST_METHOD, REQUEST_TIME, REQUEST_TIME_FLOAT, QUERY_STRING, DOCUMENT_ROOT, HTTP_ACCEPT, HTTP_ACCEPT_ENCODING, HTTP_ACCEPT_LANGUAGE, HTTP_CONNECTION, HTTP_HOST, HTTP_USER_AGENT, REMOTE_PORT, SCRIPT_FILENAME, SERVER_ADMIN, SERVER_PORT, SERVER_SIGNATURE, SCRIPT_NAME, REQUEST_URI, http_response_code) VALUES(:GATEWAY_INTERFACE, :SERVER_ADDR, :SERVER_NAME, :SERVER_SOFTWARE, :SERVER_PROTOCOL, :REQUEST_METHOD, :REQUEST_TIME, :REQUEST_TIME_FLOAT, :QUERY_STRING, :DOCUMENT_ROOT, :HTTP_ACCEPT, :HTTP_ACCEPT_ENCODING, :HTTP_ACCEPT_LANGUAGE, :HTTP_CONNECTION, :HTTP_HOST, :HTTP_USER_AGENT, :REMOTE_PORT, :SCRIPT_FILENAME, :SERVER_ADMIN, :SERVER_PORT, :SERVER_SIGNATURE, :SCRIPT_NAME, :REQUEST_URI, :http_response_code)');

$req->execute(array(
	'GATEWAY_INTERFACE' => $_SERVER['GATEWAY_INTERFACE'],
	'SERVER_ADDR' => $_SERVER['SERVER_ADDR'],
	'SERVER_NAME' => $_SERVER['SERVER_NAME'],
	'SERVER_SOFTWARE' => $_SERVER['SERVER_SOFTWARE'],
	'SERVER_PROTOCOL' => $_SERVER['SERVER_PROTOCOL'],
	'REQUEST_METHOD' => $_SERVER['REQUEST_METHOD'],
	'REQUEST_TIME' => $_SERVER['REQUEST_TIME'],
	'REQUEST_TIME_FLOAT' => $_SERVER['REQUEST_TIME_FLOAT'],
	'QUERY_STRING' => $_SERVER['QUERY_STRING'],
	'DOCUMENT_ROOT' => $_SERVER['DOCUMENT_ROOT'],
	'HTTP_ACCEPT' => $_SERVER['HTTP_ACCEPT'],
	'HTTP_ACCEPT_ENCODING' => $_SERVER['HTTP_ACCEPT_ENCODING'],
	'HTTP_ACCEPT_LANGUAGE' =>  $_SERVER['HTTP_ACCEPT_LANGUAGE'],
	'HTTP_CONNECTION' => $_SERVER['HTTP_CONNECTION'],
	'HTTP_HOST' => $_SERVER['HTTP_HOST'],
	'HTTP_USER_AGENT' => $_SERVER['HTTP_USER_AGENT'],
	'REMOTE_PORT' => $_SERVER['REMOTE_PORT'],
	'SCRIPT_FILENAME' => $_SERVER['SCRIPT_FILENAME'],
	'SERVER_ADMIN' =>  $_SERVER['SERVER_ADMIN'],
	'SERVER_PORT' => $_SERVER['SERVER_PORT'],
	'SERVER_SIGNATURE' => $_SERVER['SERVER_SIGNATURE'],
	'SCRIPT_NAME' => $_SERVER['SCRIPT_NAME'],
	'REQUEST_URI' => $_SERVER['REQUEST_URI'],
	'http_response_code' => http_response_code()
	));
}
