            "Ryan",
            "Robinson",
            "Kelly",
            "King"
        ]
},

我的php代码：

<?php

/**
 * Get the data from a JSON file.
 *
 * @return string
 */
function getData($filename)
{
    $json = file_get_contents(__DIR__ . '/names.json');;

    return (json_decode($json, true));;
}

echo '<ul>';


$array =getData('names.json'); foreach($array as $names){
    echo '<li>';
    echo $names;
    echo '</li>';
}

echo '</ol>';

错误：
