Run a php script as a background process in wamp server

Question

I have two php scripts that need to be run as continuous back ground processes in WAMP server.

Wamp server is installed in window 7 PC. These scripts are already reside in separate folder in the www root directory.

Apache Version :2.2.8
PHP Version :5.2.6

Since this is not a unix platform I can't use nohup php script.php > /dev/null & command to do this job. I'm looking for similar kind of command or method which works in wamp server windows platform.

Can anyone explain the steps I need to be taken to do this task?

Answer 1

1. create a batch file to run your php script using php executable "C:\wamp\php\php.exe C:\wamp\www\index.php"
2. add this batch file in Scheduled Task in Windows control panel.

Answer 2

Simply use this function. It works under both OSs (Windows and Linux):

function execInBackground($cmd){
    if (substr(php_uname(), 0, 7) == "Windows"){ 
        pclose(popen("start /B ". $cmd, "r"));  
    }else{ 
        exec($cmd . " > /dev/null &");   
    } 
} 

Here is an easy example of how to use the function:

execInBackground('php feed/handleFeed.php db_name '.$second_param);

In above example, we start script handleFeed.php that is located in folder named "feed" and we pass 2 parameters (database name and some other second parameter).
