PHPでセッションデータを使用

PHPで$ _SESSION関数を理解するのが難しいです。私は複数のフォームを作成していて、それが単一のフォームだったとき、すべてが期待どおりに機能しました。今私は$ _SESSIONを把握しようとしているので、page1からのデータはsubmitのためにpage2に運ばれます。PHPでセッションデータを使用

だからここページ1です：

<?php require_once("../tim/includes/validation_functions.php"); 
     include("../tim/includes/session.php"); 
     require_once("../tim/includes/variables.php"); 
     include ("/testing/tim/obervation-upload.php"); 
?> 
<?php 
session_start(); // Session starts here. 
?>

Yは、処理ページで私の少しのテストを参照してください

print "distributor: " . $distributor;

これは明らかに作業時に削除されます。

'$ _SESSION ['post'] [$ key] =それは何ですか？セッションは多次元配列ではありません。それは規則的な配列です。 '$ _SESSION ['post'] = array（）'と '$ _SESSION ['post'] [$ key] =何でも' – developerwjk

答えて

session_start（）;行を使用する必要があります。セッションを使用するすべてのページに、ファイルの最初の行として表示されます。

あなたは変数を設定することができます。

$_SESSION['username'] = "user";

をし、それらを検索：

echo $_SESSION['username'];

あなたは、その後のセッション変数を使用するには保存されたセッション

を削除する）（session_destroyを使用することができます多くのファイルにPHPがあります。

page1.php

<?php 

session_start(); 

$_SESSION['name'] = 'Example session'; 

?>

あなたは別のページでセッション変数を使用します：

page2.php

<?php 
include 'page1.php'; 

echo $_SESSION['name']; //Example session 

?>

とセッションを破壊するために、次のように試してみてください。 session_destroy（）を使用します。 unset（$ _ SESSION）;

私はこれを理解したと思います。私は2ページのコードの上にそう

2ページに移動したときに「リコール」にセッションデータを必要になった：

<?php

//store the posted values in the session variables 
$_SESSION['company_name'] = $_POST['company_name']; 
$_SESSION['date'] = $_POST['date']; 
$_SESSION['rsm'] = $_POST['rsm']; 
$_SESSION['agents'] = $_POST['agents'];
