Question

我已经使用此代码来测试json解码，但出于某种原因$config['pages'][$i]['inputs'][$j]['type']总是radio。如果我最后做$config['pages'][$i]['inputs']就没问题了，但是一旦我添加输入数字，type总是变为radio。
我的代码：

<?php
$configFilePath = $_SERVER["DOCUMENT_ROOT"] . "/wms/config/author_submit.json";
$configFile = fopen($configFilePath, "r") or die("Unable to open file config.json"); // open config file
$config = fread($configFile,filesize($configFilePath)) or die("unable to read config.json"); // read config file
$config = json_decode($config, true) or die('json decoding failed');                    // decode config file
?>

<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <form action="upload.php" method="post" enctype="multipart/form-data"> <!-- start form -->
        <?php
        var_dump($config);
        echo "<br><br>";
        for ($i=0; $i < count($config['pages']); $i++)
        {
            echo "page" . $i . "<br><br>";
            for ($j=0; $j < count($config['pages'][$i]['inputs']); $j++)
            {
                echo $config['pages'][$i]['inputs'][$j]["name"] . "<br>";
                if ($config['pages'][$i]['inputs'][$j]['type'] = "radio")
                {
                    echo $i . $j . "<br>";
                    var_dump($config['pages'][$i]['inputs'][$j])
                    echo "<br><br>";
                }
            }
        }
        ?>
    </form>
</body>

等于论证需要两个=符号只有一个将设置变量，而不是比较它。

if ($config['pages'][$i]['inputs'][$j]['type'] == "radio")

php：嵌套关联数组不输出corectly
