Question

我将多个表单输入值存储为MySql中的序列化数据：

if(isset($_POST['bts'])):
      $id = "175";
      if(isset($_POST['bts'])){
         $stmt = $mysqli->prepare("UPDATE personal SET invoice=? WHERE id_personal=?");
         $stmt->bind_param('ss', serialize($_POST), $id);        
         if($stmt->execute()):

HTML：

<form role="form" method="post" id="form">
    <input type="text" class="form-control" name="nazov[]" id="nazov">
    <input type="text" class="form-control" name="cena[]" id="nazov">
    <button id="save"class="btn btn-success btn-lg" name="bts">Save</button>
    <button id="saveprint" class="btn btn-success btn-lg" name="bts"><span class="glyphicon glyphicon-print" aria-hidden="true"></span>Save and print</button>
</form>

使用jQuery我动态添加输入，因此有3个额外的输入行示例序列化数据：

 a:3:{s:5:"nazov";a:3:{i:0;s:3:"123";i:1;s:3:"789";i:2;s:3:"abc";}s:4:"cena";a:3:{i:0;s:3:"456";i:1;s:6:"101112";i:2;s:3:"def";}s:3:"bts";s:0:"";}

或

Array
(
    [nazov] => Array
        (
            [0] => 123
            [1] => 789
            [2] => abc
        )

    [cena] => Array
        (
            [0] => 456
            [1] => 101112
            [2] => def
        )

    [bts] => 
)

我的问题是：在foreach函数中检索（反序列化和获取）此数据的最佳方法是什么？

$res = $mysqli->query("SELECT invoice FROM personal WHERE id_personal='175'");
$row = mysqli_fetch_assoc($res);
$unsRow = unserialize($row['invoice']);
foreach ($unsRow as $value) {
  echo $value['nazov'];
}

Undefined index: nazov

期望的结果是：

Nazov:123 Cena:456
Nazov:789 Cena:101112
Nazov:abc Cena:def

Answer 1

使用当前的json字符串，您可以获得配对值，如：

$res = $mysqli->query("SELECT invoice FROM personal WHERE id_personal='175'");
$row = mysqli_fetch_assoc($res);
$unsRow = unserialize($row['invoice']);
// check if you have `nazov`key and `cena` key, cause you need price too
if ($unsRow['nazov'] && $unsRow['cena']) {
    foreach ($unsRow['nazov'] as $k => $v) {
        if (!empty($unsRow['cena'][$k])) {
            echo 'Nazov: ' . $v . ', cena: ' . $unsRow['cena'][$k];
        }else
            echo 'Nazov: ' . $v . ', cena: ' . "";
    }
}

Answer 2

这不是一个特别有用的存储机制，但这可行。

$unsRow = unserialize($row['invoice']);

for ( $i=0; $i<count($unsRow ); $i++) {
    echo sprintf( "Nazov:%d Cena:%d\n", 
                       $unsRow ['nazov'][$i], 
                       $unsRow ['cena'][$i] 
                );
}
