我有一个php变量，其中包含一些html内容和一些href链接。我需要捕获这些链接，保存到数据库中，并将其替换为我刚刚保存的行的id（即在时事通讯应用程序中跟踪有多少人关注该链接）。
基本上，我需要做示例中的2个函数（some_function_to_save_the_links_to_array和some_functions_to_save_the_links_to_arrays）。
非常感谢你的帮助！
示例：
$var = "<html><body><h1>This is the newsletter</h1><p>Here I have <a href='http://www.google.com'>Some links</a> in the body of this <a href='http://www.yahoo.com'>Newsletter</a> and I want to extract their.</body></html>";
//Here I just no know how to do this, but I need to save http://www.google.com and http://www.yahoo.com to, maybe, an array, and save this array in a mysql db.
some_function_to_save_the_links_to_array;
while (THERE ARE VALUES IN THE ARRAY OF THE LINKS){
save $array['X'] to db //(I already know how to do it, this is not the problem)
$id = last inserted row in db //I know how to do it also
function_to_replace_the_links_for_the_id;
}
echo $var;
And this is the echo:
<html><body><h1>This is the newsletter</h1><p>Here I have <a href='http://www.mysite.com/link.php?id=1'>Some links</a> in the body of this <a href='http://www.mysite.com/link.php?id=1'>Newsletter</a> and I want to extract their.

}

{

//str_replace working faster than strtr
