其实我在《把文本中的URL地址转换为可点击链接的JavaScript、PHP自定义函数》一文中介绍过PHP代码如何实现将URL地址转化成链接的方法,今天给大家介绍一个更加简洁的版本,先来看看PHP的源代码:

/** * Author: SeeDZ * From: http://code.seebz.net/p/autolink-php/ **/ function autolink($str, $attributes = array()) { $attrs = ''; foreach ($attributes as $attribute=>$value) { $attrs .= " {$attribute}=\"{$value}\""; } $str = ' '.$str; $str = preg_replace('`([^"=\'>])((http|https|ftp|ftps)://[^\s< ]+[^\s<\.)])`i', '$1$2', $str); $str = substr($str, 1); return $str; }
Copy after login

怎么样,很简洁吧!看看函数的API文档吧:

语法

string autolink ( string $str [, array $attributes = array() ] )
Copy after login

参数介绍

str – 必选(String 类型数据)。需要查询替换的文本。
attributes -可选(Array 类型数据)。替换链接的一些可选参数。

返回值

返回替换后的文本。

autolink() 调用方法

autolink使用起来也很方便,我们可以只传一个参数,即为必选的需要替换的字符文本。例如:

http://example.com/?param=value#anchor. ?>
Copy after login

另外我们还可以设置一些额外的链接的参数,可以让生成的链接在新窗口中打开,或者不希望搜索引擎索引替换的链接。例如:

"_blank","rel"=>"nofollow")); echo $str; // http://example.com/ ?>
Copy after login
