php - 如何在没有 key 的情况下解码 JSON 值？

Question

我有json

{"http://www.google.com/","http://www.facebook.com/","http://www.wordpress.com/",0}

我怎样才能像这样打印

 http://www.google.com/
 http://www.facebook.com/
 http://www.wordpress.com/

Answer 1

你可以使用这个功能

function getUrls($string) {
        $regex = '/https?\:\/\/[^\" ]+/i';
        preg_match_all($regex, $string, $matches);
        //return (array_reverse($matches[0]));
        return ($matches[0]);
}

像这样

$json_str = '{"http://www.google.com/","http://www.facebook.com/","http://www.wordpress.com/",0}';
$arr = getUrls($json_str);

echo "<pre>";
print_r($arr);

输出:

Array
(
    [0] => http://www.google.com/
    [1] => http://www.facebook.com/
    [2] => http://www.wordpress.com/
)
