问题描述

我现在用的是TinySong API生成一个链接，它的工作原理，现在我试图用一个linkify它。事实并非如此。我不知道为什么它不linkifing我相信我用正确的变量。这里是code。

I am using the TinySong api to generate a link, It works, now I tried using a linkify for it. It didn't. I'm not sure why it is not linkifing I believe I used the right variable. Here is the code.

<?php
  // linkify URLs
  $pre = preg_replace(
    '/(https?:\/\/\S+)/',
    '<a href="\1">\1</a>',
    $pre
  );
?>
 <script src="http://platform.twitter.com/anywhere.js?id= MY API KEY&v=1" type="text/javascript"></script>
<?php



class Tinysong
{
    protected $api_key = '';
    protected $method = '';
    protected $limit = '';
    protected $query_string = '';


    public static $CURL_OPTS = array(
        CURLOPT_CONNECTTIMEOUT => 10,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_TIMEOUT        => 60,
        CURLOPT_USERAGENT      => 'tinysong-php-0.7',
    );


    public function __construct($api_key)
    {
        $this->api_key = $api_key;

    }




    /**

    public function single_tinysong_link($query_string)
    {
        $this->query_string($query_string);
        return $this->method('a');
    }

       public function search($query_string)
    {
        $this->query_string($query_string);
        return $this->method('a');

推荐答案

这是对我使用它的网站运作良好...

This is working well on the sites I am using it for...

function find_urls($t){
    $reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
    // Check if there is a url in the text
    if(preg_match($reg_exUrl, $t, $url)) {
        $add='';
        if (substr($url[0],(strlen($url[0])-1),strlen($url[0]))==")"){
            $url[0]=substr($url[0],0,(strlen($url[0])-1));
            $add=')';
        } else if (substr($url[0],(strlen($url[0])-1),strlen($url[0]))=="]"){
            $url[0]=substr($url[0],0,(strlen($url[0])-1));
            $add=']';
        }
        // make the urls hyper links
        return preg_replace($reg_exUrl, '<a href="'.$url[0].'">'.$url[0].'</a>'.$add, $t);
    } else {
        // if no urls in the text just return the text
        return $t;
    }
}
