字符串在最右边的字符后替换

Question

这是我的角色

/public/proj/index.php/home
/public/proj/index.php/test
/public/proj/home
/public/proj/test

我只需要在最右边的字符后面替换字符＆＃39; /＆＃39;登录。所以它将是

/public/proj/index.php/login
/public/proj/index.php/login
/public/proj/login
/public/proj/login

Answer 1

这应该适合你：

$str = "/public/proj/home";
echo $str = substr_replace($str, "login", -1*(strlen(basename($str))), strlen(basename($str)));

输出：

/public/proj/login

Answer 2

试试这个 -

$str = "/public/proj/index.php/home";
$vals = explode('/', $str);
$vals[count($vals)-1] = 'login';
$str = implode('/', $vals);
var_dump($str);
