这是JSON数组吗? [英] Is this a JSON array?

问题描述

这是JSON数组吗: http://flamencopeko.net/icons_ajax.php ?

来源: http://flamencopeko.net/icons_ajax.txt

$urls = array(); foreach (glob(dirname(__FILE__) . '/ico/*.gif') as $file) { $urls[] = 'http://flamencopeko.net/ico/' . basename($file); };

$index = 0;

if (isset($_GET['index'])) {
    $index = (int) $_GET['index'];

    if ($index > (count($urls) - 1)) {
        // Out of bounds, reset
        $index = 0;
    }
}

$previous = $index - 1;
$next = $index + 1;

if ($previous < 0) {
    $previous = count($urls) - 1;
}

if ($next == count($urls)) {
    $next = 0;
}

echo json_encode(array(
    'total' => count($urls),
    'url'   => $urls[$index],
    'next'  => $next,
    'prev'  => $previous,
    'alls' => $urls
));

我正在尝试将其与php一起使用.与JavaScript一起使用.我已经尝试过json_decode()等等，但是还没有输出.

解决方案

我喜欢在 http上使用在线json查看器://jsonviewer.stack.hu/-显示您有一个有效的json对象；您可以使用它来查看它包含一些标头信息和"alls"数组中的406个图像数组.

$next = $index + 1;

if ($previous < 0) {
    $previous = count($urls) - 1;
}

if ($next == count($urls)) {
    $next = 0;
}

echo json_encode(array(
    'total' => count($urls),
    'url'   => $urls[$index],
    'next'  => $next,
    'prev'  => $previous,
    'alls' => $urls
));

I'm trying to use it with php. Works with JavaScript. I've tried json_decode() and more, but no output yet.

解决方案

I like to use the online json viewer at http://jsonviewer.stack.hu/ - which shows you have a valid json object; which you could use to see that it consists of some header info and an array of 406 images in the 'alls' array.
