I used file_get_content() function to get the content of another page, then use substr function cut the content i need and echo it in my page. But i wonder if that page have change the content( by query data in database ) and my content substr from that page will be not correct and my page layout will break! How can i use another function instead of substr function??

If you use some other function then also it will break because you should be having the provision for the changes that may happen at the source or what you could do it have the content and instead of displaying it directly you could insert into the database.

You need to design a better algo rather than just to use the API for it.
