Problems with accessing two php pages at the same time

* **. Php: *** echodate (& #39; h: I: s & #39 ;). & quot; n & quot; sleep (10); echodate (& #39; h: I: s & #39 ;). & quot; n & quot; *** B. php: *** phpinfo (); environment: nginx + php-cgi if I access B directly. php will immediately display the phpinfo information. if I access. php, will wait 10 seconds for php

**A. php:**

Echo date ('H: I: s'). "\ n ";
Sleep (10 );
Echo date ('H: I: s'). "\ n ";

**B. php:**

Phpinfo ();

Nginx + php-cgi

If I access B. php directly, the phpinfo information will be immediately displayed.
If I access a. php directly, I will wait 10 seconds to display the information.

If I access a. php first and access B. php in another tag, why does it take 10 seconds for both pages to be displayed together?

Thank you for choosing php Cainiao...
