如何使用PHP从html中提取数据

I am trying to get data(like job vacancy) from page like http://www.quest.edu.pk/jobs/.I dont know how to get this.can anyone help me in doing this. Thanku in advance.

php has inbuilt function file_get_contents to extract complete html source of webpage - like below:

$html=file_get_contents("http://www.quest.edu.pk/jobs/")

But its not recommended because we can not set timeout parameter in function. So instead of this you can use curl library and preg_match as suggested by @Sunil Pachlangia & @Noman.

you can refer this Link for more information.
