如果我输入
www.google.com或者http://www.google.com
使用auto_link()功能将正确添加链接..
但是，如果我输入
google.com
自 www 以来，该功能不起作用。部分不见了……
我如何确保它也包含这些链接？
这是来自codeigniter的功能：
/**
* Auto-linker
*
* Automatically links URL and Email addresses.
* Note: There's a bit of extra code here to deal with
* URLs or emails that end in a period. We'll strip these
* off and add them after the link.
*
* @access public
* @param string the string
* @param string the type: email, url, or both
* @param bool whether to create pop-up links
* @return string
*/
if ( ! function_exists('auto_link'))
{
function auto_link($str, $type = 'both', $popup = FALSE)
{
if ($type != 'email')
{
if (preg_match_all("#(^|\s|\()((http(s?)://)|(www\.))(\w+[^\s\)\<]+)#i", $str, $matches))
{
$pop = ($popup == TRUE) ? " target=\"_blank\" " : "";
for ($i = 0; $i < count($matches['0']); $i++)
{
$period = '';
if (preg_match("|\.$|", $matches['6'][$i]))
{
$period = '.';
$matches['6'][$i] = substr($matches['6'][$i], 0, -1);
}
$str = str_replace($matches['0'][$i],
$matches['1'][$i].'<a href="http'.
$matches['4'][$i].'://'.
$matches['5'][$i].
$matches['6'][$i].'"'.$pop.'>http'.
$matches['4'][$i].'://'.
$matches['5'][$i].
$matches['6'][$i].'</a>'.
$period, $str);
}
}
}
if ($type != 'url')
{
if (preg_match_all("/([a-zA-Z0-9_\.\-\+]+)@([a-zA-Z0-9\-]+)\.([a-zA-Z0-9\-\.]*)/i", $str, $matches))
{
for ($i = 0; $i < count($matches['0']); $i++)

$period = '';
if (preg_match("|\.$|", $matches['3'][$i]))

$str = str_replace($matches['0'][$i], safe_mailto($matches['1'][$i].'@'.$matches['2'][$i].'.'.$matches['3'][$i]).$period, $str);

这解决了我的问题，因此用户输入的任何链接都会找到它并添加链接......即使用户输入电子邮件，它也不会在域部分添加链接，而是将其显示为文本。
