AJAX函数在PHP文件中访问PHP函数

I have a working AJAX file that will execute the content in a PHP file. However, if the php is within the function(there are alot of php funtion in a PHP file), how do I call only the function that I want.

My AJAX code:

$(document).ready(function(){

// use ajax, call the PHP
$.ajax({
    url: 'postme.php', 
    success: function(response){
        $('.result_Postme').text(response);
    }
})
});

one of the function in postme.php PHP file:

<?php 
  function echo()
  {
    echo 'Text';
  }
?>

Thanks.

EDIT:

@Amadan hi, i tried ur method but it doesn't seems to be outputting in the html.

My AjAx code:

$(document).ready(function(){

// use ajax, call the PHP
$.ajax({
    url: 'rank.php', 
    data: {
        action: 'echo'
    },
    success: function(response){
        $('.rank_Alibaba').text(response);
    }
})
});

PHP file

switch($_REQUEST['action']) 
{
 case 'echo': 
 echo "text";
 break;
 }

HTML:

 <td class="rank_Alibaba"></td>

    a) Use a MVC framework, such as Laravel or CakePHP. Such frameworks are quite opinionated and will force best practices on you, whether you want them or not. :P

    b) If you absolutely want to stick with plain PHP, the easiest way is to pass a parameter to select your function, and then in your PHP file have a switch statement on that parameter that will dispatch the call to the correct place. For example, in JavaScript:

    ...
    url: 'postme.php', 
    data: {
      action: 'echo'
    },
    ...
    

    In PHP:

    switch($_REQUEST['action']) {
      case 'echo':
        echo();
        break;
      ...
    }
