問題描述

我想在一個文件中執行查詢，將其存儲在會話變量中，然后在另一個文件中訪問結果.

I want to execute a query in one file, store it in a session variable, and access the result in another file.

File1.php:

//This is the file I have executed my sql statement in
//I have already done session_start(); and initialized $conn
$query = //my query. I know it is working because I have tested it elsewhere, so I 
         // don't believe it is the problem
$_SESSION['query2'] = mysqli_query($conn, $query)

File2.php:

//This is the file I want to access my query results in.
//I have already done session_start(); and initialized $conn

$tempArray =  $_SESSION['query2'];

if (isset($tempArray)) {
    $row = mysqli_fetch_array($tempArray, MYSQL_NUM);
    if ($row == null) {
        echo "<h1> error </h1>"; //This line gets executed
    } else {
        echo "<h1> works! </h1>";
    }
} else {
    echo "<h1> array not set </h1>";
}

對我做錯了什么有任何想法嗎?或者，有沒有其他方法可以完成我在這里嘗試做的事情?

Any ideas as to what I am doing wrong? Or, is there another way to accomplish what I'm trying to do here?

推薦答案

在會話中存儲實際數組:

Store the actual array in session:

File1.php:

$query = //my query. 
$result = array();
$res = mysqli_query($conn, $query);
while($row = mysqli_fetch_array($res, MYSQL_NUM){
    $result[] = $row;
}
$_SESSION['query2'] = $result;

File2.php:
//I have already done session_start(); and initialized $conn

$tempArray =  $_SESSION['query2'];
var_dump($tempArray);
