У меня есть файл sess_function.php
В этом файле перечислены различные (6) функции, используемые для управления сеансами.
function _open()
{
try{
// Open the database
$dbh = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
} //try
catch(PDOException $e){
echo "Oops, We're experiencing an error CONNECTING.";
file_put_contents('PDODBConnectionErrors.txt', $e->getMessage(), FILE_APPEND);
} //catch
}
## Kill Connection to Mysql (Using PDO)
function _close(){
$dbh = null;
}
## Read a current session
function _read($id){
try{
// Open the database
$dbh = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// Begin Query
$id = mysql_real_escape_string($id);
$sth = $dbh->prepare("SELECT data FROM sessions WHERE id = '$id'");
$sth->execute();
}
catch(PDOException $e){
echo "Oops, We're experiencing an error. READING";
file_put_contents('PDODBConnectionErrors.txt', $e->getMessage(), FILE_APPEND);
} //catch
## return '';
}
## Write to current session
function _write($id, $data){
// WRITE Vars
try{
// Open the database
## require_once('dbi.php');
$dbh = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// Begin Query
$access = time();
$id = mysql_real_escape_string($id);
$access = mysql_real_escape_string($access);
$data = mysql_real_escape_string($data);
$sth = $dbh->prepare("REPLACE INTO sessions VALUES ('$id', '$access', '$data')");
$sth->execute();
}
catch(PDOException $e){
echo "Oops, We're experiencing an error. REPLACING SESSION VAL";
file_put_contents('PDODBConnectionErrors.txt', $e->getMessage(), FILE_APPEND);
} //catch
}
## Destroy current session
function _destroy($id){
try{
// Open the database
## require_once('dbi.php');
$dbh = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// Begin Query
$id = mysql_real_escape_string($id);
$sth = $dbh->prepare("DELETE FROM sessions WHERE id = '$id'");
$sth->execute();
}
catch(PDOException $e){
echo "Oops, We're experiencing an error.";
file_put_contents('PDODBConnectionErrors.txt', $e->getMessage(), FILE_APPEND);
} //catch
}
## Clean old session data out
function _clean($max){
try{
// Open the database
## require_once('dbi.php');
$dbh = new PDO("mysql:host=$host;dbname=$dbname",$user,$pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
// Begin Query
$old = time() - $max;
$old = mysql_real_escape_string($old);
$sth = $dbh->prepare("DELETE FROM sessions WHERE access < '$old'");
$sth->execute();
}
catch(PDOException $e){
echo "Oops, We're experiencing an error. DEL FROM SESSION";
file_put_contents('PDODBConnectionErrors.txt', $e->getMessage(), FILE_APPEND);
} //catch
}
и index.php

Таблица выглядит так:
Проблема в том, что это не доставляет мне проблем, но в таблице sessions ничего не хранится ...
если я ОБЯЗУЕТСЯ session_start(); он выдает следующие предупреждения:
Oops, We're experiencing an error. READING
Warning: session_start() Cannot send session cookie - headers already sent by sess_function.php:33)index.php on line 12
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started sess_function.php:33) in index.php on line 12
Любой ??
