用PHP将网址字符串转换成超链接(网址或email)

 代码如下:

function makeClickableLinks($text) { 
$text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_+.~#?&//=]+)', '
\1
', $text); 
$text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_+.~#?&//=]+)','\1
\2
', $text); 
$text = eregi_replace('([_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3})', '
\1
', $text); 
return $text; 
}
