Php 在字符串中的所有图像之后添加类似Facebook的按钮

我怎样才能添加类似facebook的按钮，毕竟图片是字符串

例如：

<p>This is some text. This is some text. This is image: <img src='url'/>. This is some tekst. This is new image: <img src='url'></p>

我想改变一下：

<p>This is some text. This is some text. This is image: <img src='url'/><facebook like buuton>. This is some tekst. This is new image: <img src='url'> <facebook like button></p>

使用jQuery：

JAVASCRIPT

您想要什么？img url？还是窗口的当前url？

$(document).ready(function() {
   $("img").each(function() {  
    $(this).after('<facebook like buuton>');
  });  
});
