使用jQuery或PHP的文本比较

Question

我有2个字符串作为示例，并且想要查看两个字符串的TEXT是否都是EXACT。如果STRING不匹配，应显示哪些字符串是STRING或缺少的句子原始字符串。

jQuery中有可能吗？任何代码？

我试图用大量的在线文本比较工具，但没有人说，以下字符串是准确的，并没有什么区别，需要忽略段落

In this chapter, you learn some real time-savers. If you are tired of defining 
the same layers, along with units, grid, snap, and ltscale, for each new 
drawing, read on. You are about to learn how to create your own template 
drawings. With templates, you can begin each new drawing with setups 
you have defined and saved in previous MEMA sessions, or with a 
variety of predefined setups included in the software. 
In addition, you learn to reshape the grid using the LIMITS command 
and to copy, move, and array objects on the screen so that you 
do not have to draw the same thing twice. We begin with the LIMITS 
command, because we want to change the limits as part of defining 
your first template.

您正在寻找一个“差异”实现，这并不是微不足道的。在PHP和JavaScript中都可能。
