PHP methods to achieve multi-process under Linux Share

Php compile time, need to add -enable-pcntl, and is recommended only run in CLI mode, do not run the WEB server environment.

The following PHP to achieve multi-process simple test code:

code show as below:

<? PHP
 DECLARE (ticks = 1 );
 $ bWaitFlag = FALSE ; // / whether to wait for the end of the process 
$ intNum = 10; // total / process 
$ PIDS = Array (); // / PID process array 

echo ( "Start \ n-" ); 

for ( $ I = 0; $ I < $ intNum ; $ I ++ ) { 

$ PIDS [ $ I ] = pcntl_fork (); // / generating sub-process, but apart from the current line under test run code, and data information does not inherit the parent process 

IF (! $ PIDS [ $ i ]) {
// the child process code segment _start 
$ STR = "" ;
 SLEEP (5+ $ I );
 for ( $ J = 0; $ J < $ I ; $ J ++) { $ STR =. "*" ; }
 echo " $ I . ->" Time . () " $ STR \ n-" ;
 Exit ();
 // the child process code segment _END 
} 

} 
IF ( $ bWaitFlag ) 
{ 
for ( $ I = 0; $ I < $ intNum ; $ I ++) {
pcntl_waitpid($pids[$i], $status, WUNTRACED);
echo "wait $i -> " . time() . "\n";
}
}
echo ("End\n");
?>
