"Error: headers already sent" appears during Zend framework installation"

I suddenly got a new project and used Zend framework and extjs to do it. I am not familiar with these two frameworks, so I am also familiar with these two frameworks while being familiar with the business.

 

The following error is reported during local Configuration:

Fatal Error
: Uncaught exception 'zend _ session_exception'
Message 'session must be started before any output has been sent to
Browser; Output started in

1> set session. save_path to a readable folder.

2>; initialize Session on request startup.
Session. auto_start = 0

 

3> mod_rewrite.so In the httpd. conf configuration file of Apache is also enabled.

.......

Finally, the problem is found.php.ini
,"output_buffering
= 65535
"A buffer of 64 K is allowed. My local output_buffering = off finally solved this problem.

 

 

This problem is solved by finding a solution from the official introduction of Zend framework.
