使用php将json对象转换为数组

Question

当我想要

时，我想逐个回显json数组中的值

<?php
    function get_web_page($url) {
        $options = array(
            CURLOPT_RETURNTRANSFER => true,   // return web page
            CURLOPT_HEADER         => false  // don't return headers
        );

        $ch = curl_init($url);
        curl_setopt_array($ch, $options);

        $content  = curl_exec($ch);

        curl_close($ch);

        return $content;
    }
$response = get_web_page("http://maps.googleapis.com/maps/api/geocode/json?address=colombo");
$resArr = array();
$resArr = json_decode($response);
echo "<pre>";
print_r($resArr);
echo "</pre>";
echo "<br>";
echo "<br>";
;

?>

这是代码

上方的浏览器中的当前结果

Answer 1

尝试：

$resArr = json_decode($response, true);

它会将其转换为关联数组格式。
