我试图在我的 mysql 查询中使用 Goo.gl 类（网址缩短器）。

我通过 mysql_fetch_array 从数据库中获取 10 行；并且需要为所有行创建 url。

像这样：

while ($f = mysql_fetch_array($q)) {
$short_url = $googl->shorten("http://www.example.com/$f[news]"); 
echo $short_url; }

但脚本只为第一个创建 url。

你有什么想法吗，我如何使用这个脚本进行多个 url 转换（为所有 mysql_query 行创建 url）。

这是我使用的脚本：

class Googl
{
    public $extended;
    private $target;
    private $apiKey;
    private $ch;

private static $buffer = array();

function __construct($apiKey = null) {
    # Extended output mode
    $extended = false;

    # Set Google Shortener API target
    $this->target = 'https://www.googleapis.com/urlshortener/v1/url?';

    # Set API key if available
    if ( $apiKey != null ) {
        $this->apiKey = $apiKey;
        $this->target .= 'key='.$apiKey.'&';
    }

    # Initialize cURL
    $this->ch = curl_init();
    # Set our default target URL
    curl_setopt($this->ch, CURLOPT_URL, $this->target);
    # We don't want the return data to be directly outputted, so set RETURNTRANSFER to true
    curl_setopt($this->ch, CURLOPT_RETURNTRANSFER, true);
}

public function shorten($url, $extended = false) {

    # Check buffer
    if ( !$extended && !$this->extended && !empty(self::$buffer[$url]) ) {
        return self::$buffer[$url];
    }

    # Payload
    $data = array( 'longUrl' => $url );
    $data_string = '{ "longUrl": "'.$url.'" }';

    # Set cURL options
    curl_setopt($this->ch, CURLOPT_POST, count($data));
    curl_setopt($this->ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($this->ch, CURLOPT_HTTPHEADER, Array('Content-Type: application/json'));

    if ( $extended || $this->extended) {
        return json_decode(curl_exec($this->ch));
    } else {
        $ret = json_decode(curl_exec($this->ch))->id;
        self::$buffer[$url] = $ret;
        return $ret;
    }
}

public function expand($url, $extended = false) {
    # Set cURL options
    curl_setopt($this->ch, CURLOPT_HTTPGET, true);
    curl_setopt($this->ch, CURLOPT_URL, $this->target.'shortUrl='.$url);

    if ( $extended || $this->extended ) {
        return json_decode(curl_exec($this->ch));
    } else {
        return json_decode(curl_exec($this->ch))->longUrl;
    }
}

function __destruct() {
    # Close the curl handle
    curl_close($this->ch);
    # Nulling the curl handle
    $this->ch = null;
}
}$googl = new Googl();
