From jQuery you can only call php script with this function. Like that:
在 jQuery 中，您只能使用此函数调用 php 脚本。像那样：
$.ajax({
url: 'hello.php',
success: function (response) {//response is value returned from php (for your example it's "bye bye"
alert(response);
}
});
hello.php
你好.php
<?php
echo "bye bye"
?>

}

$validFunctions = array("hello","anotherF");
$functName = $_REQUEST['f'];
if(in_array($functName,$validFunctions))
{
$$functName();
}else{
echo "You don't have permission to call that function so back off!";
exit();
}
function hello()
{
echo "bye bye";
}
function anotherF()

echo "the other funct";

function noTouch()

this is a little example of really basic and pretty ugly RMI type invocation of php methods via ajax
这是通过 ajax 调用 php 方法的非常基本和非常丑陋的 RMI 类型的一个小例子

PHP is something that is executed on the server, the client (browser) has no direct access to any of the PHP code that is being executed. This is very nice because otherwise everyone could access all files and your entire mysql database.
PHP 是在服务器上执行的东西，客户端（浏览器）无法直接访问任何正在执行的 PHP 代码。这非常好，否则每个人都可以访问所有文件和整个 mysql 数据库。
You can combine php and javascript (jquery) with AJAX or a library like xajax.
您可以将 php 和 javascript (jquery) 与 AJAX 或类似 xajax 的库结合使用。

php is server side language, js - client side... I think you should use ajax. or your php function should return valid javascript code
php 是服务器端语言，js - 客户端......我认为你应该使用 ajax。或者你的 php 函数应该返回有效的 javascript 代码
