Question

如何通过php类中的所有函数保留post变量？我正在函数中访问数组中的post变量。但是当我尝试访问另一个函数中的那些时，它只会重新计算数组中的最后一个元素。

foreach ( $questionAry as $questionID )
{
        $questionName = $this->htmlID_questionID . $questionID;

        $question_answer = $_POST[$questionName];                   

        $_SESSION['qusID'] = $questionID;
        $_SESSION['qusanswer'] = $question_answer;
}

我想在另一个函数中访问$ questionID和$ question_answer。我尝试通过会话来完成，但我只能访问最后一个值。

你的循环错了......这些人在每次迭代时都会被覆盖

    $_SESSION['qusID'] = $questionID;
    $_SESSION['qusanswer'] = $question_answer;

您需要使用索引循环，类似于......

foreach ( $questionAry as $key => $questionID )
{
        $questionName = $this->htmlID_questionID . $questionID;

        $question_answer = $_POST[$questionName];                   

        $_SESSION['qusID'][$key] = $questionID;
        $_SESSION['qusanswer'][$key] = $question_answer;
}

编辑：根据下面的对话，尝试类似的事情。

function getvalues() { 
    $questions = array();
    $jsonEncoded = ( get_magic_quotes_gpc() ) ? stripslashes($_POST[$this->htmlID_questionIDAry]) : $_POST[$this->htmlID_questionIDAry]; 
    $jsonDecoded = json_decode($jsonEncoded); 

    $questionAry = explode(",",$jsonDecoded->list); 
    $instr = ""; 

    foreach ( $questionAry as $key => $questionID ) { 
        $questions[$key]['name'] = $this->htmlID_questionID . $questionID; 
        $questions[$key]['answer'] = $_POST[$questionName]; 
    } 

    return $questions;
}


$parsedQuestions = getvalues();

name_of_other_function($parsedQuestions);

function name_of_other_function($parsedQuestions){
    print_r($parsedQuestions);
}

访问数组中的post变量
