Use Ob_flush tip: E_warning:cannot Modify header Information-headers already sent
How can I resolve this?
The code is as follows:
echo $show _msg. "";
Ob_flush ();
Flush ();

The error message has been written clearly, the response header has been output, so you can no longer modify the header information
Should be you do not open a new layer of OB, directly output the data (at the same time output the response header), the default is directly sent to the browser
Using OB normally is the first to write the data in the OB, and then output the content of the OB when it is finished.

Unless there is a syntax error, there is nothing wrong with #10 code!
But in the back of the header, Session_Start, Setcookie One, it could be wrong
You'd better put out the complete error message.
