POIf i use session_start in function it starts session but doesn't output sessions
text
Body
copied!<p>The function is called on every possible page, and it's something like main function it checks if user is logedin or not, so it's executed before anything. It just check if user is logedin or have cookie set and if it's logedin or have cookie it starts session and set 2 sessions.</p> <p>But outputting sessions outside function it outputs that sessions are not set, but shows cookie and session.</p> <p>To explain a bit more if i echo</p> <pre><code>$_SESSION['user'] $_SESSION['logedin'] </code></pre> <p>It outputs </p> <pre><code>Undefined variable: _SESSION </code></pre> <p>But if i do</p> <pre><code>print_r($_COOKIE); </code></pre> <p>It outputs</p> <pre><code>Array ( [PHPSESSID] => 1rane5lksksp7s4u8p8fh0h194 [user] => fe8dc8f2a7e88746fd8586d489646958 ) </code></pre> <p>Which means that both session and cookie are set</p> <p>But why it shows me Undefined variable when i request a session and also it logout user after first refresh of website.</p> <p>Is it because session_start is inside a function, if session_start is called inside a function it is called only when that function meets the criteria of else or if statements inside function, and once session_start is called it is remembered in browser or on every page call you need to use session_start to start a session and than you can use sessions that are set. Because if i put session_start outside function it works flawlessly but session is started even if user is not logedin. </p>
