Php multi-thread Q & A. How can this problem be solved?

Php multi-thread Q & a I have seen some demos on the internet. many of them are the same. I got a local test and encountered a problem: // a. php & nbsp; & lt ;? Phpfunction & nbsp; runThread () {& nbsp; $ fp & nbsp; = & nbsp; fsockopen ('localhost', & nbsp; 80, & n php multi-thread Q &
I saw some demos on the Internet, many of which were the same. I got the local test and encountered a problem:
// A. php
Function runThread (){
$ Fp = fsockopen ('localhost', 80, $ errno, $ errmsg );
Fputs ($ fp, "GET/a. php? Act = B ");
Fclose ($ fp );
}

Function (){
$ Fp = fopen ('result _ a. log', 'w ');
Fputs ($ fp, 'set in'. Date ('H: I: S', time (). (double) microtime (). "\ r \ n ");
Fclose ($ fp );
}

Function B (){
$ Fp = fopen ('result _ B. log', 'w ');
Fputs ($ fp, 'set in '. date ('H: I: S', time ()). (double) microtime (). "\ r \ n"); fclose ($ fp );
}

If (! Isset ($ _ GET ['AC']) $ _ GET ['AC'] = 'a ';

If ($ _ GET ['act '] = 'a '){
RunThread ();
A ();
}
Else if ($ _ GET ['AC'] = 'B') B ();
?>

Each time I access localhost/. in php, records can only be written to result_a.log, but will never be written to result_ B .log. I am sure that fsocket extension can be enabled in my php environment, could you give me some advice on multithreading php:
------ Solution --------------------
Because your default $ _ GET ['AC'] is to execute the () function.
Run localhost/a. php? Try act = B
------ Solution --------------------
It should be caused by missing headers of data packets in fputs.
My opinion:
1. use firebug to know what to write and observe the header of your request.
2. discard the fsock series functions. this is not supported in many places, but you can use curl to simulate your request.
------ Solution --------------------
Use firebug to check for errors, or use echo to check where the program is executed? The check fails.
