如何顯示數組中的變量

Question

我正在嘗試顯示數組中的變量。 我的密碼

<?php
    $quesid = array();
    $quid = $_POST["qid"];
    print_r($quid);
    foreach ($que as $quid) {      
        $quesid = $que[0][$j];
        echo $quesid;
    }
?>

這是行不通的。 但是print_r($quid); 顯示數組元素：

 Array ( ['1'] => 54 ['2'] => 55 ['3'] => 56 ['4'] => 57 ['5'] => 58 ['6'] => 59 ['7'] => 60 ['8'] => 64 ['9'] => 65 ['10'] => 66 ['11'] => 76 ['12'] => 77 ['13'] => 78 )

Answer 1

<?php
        $quid = $_POST["qid"];
        print_r($quid);
        foreach ($quid as $key=>$value) {      
        $quesid=$value;
        echo $quesid;}
        ?>

Answer 2

您的foreach表達式順序錯誤：

<?php 
$quids = $_POST["qid"]; 
foreach ($quids as $k=>$quid){ 
    echo $quid."<br>"; 
}
?>
