I found this on PHP.net: http://us.php.net/manual/en/function.exec.php Note: If you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends. This is what I want... I want to execute another PHP script from the CLI, pass it a parameter and let it go to town after the HTTP request closes. Can someone please illustrate how I can make this work? Thx, Brad -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It seems the script is calling itself even though I'm specifying a different script to run... test2.php <?php echo "Hello, World!"; ?> test1.php <?php

      if( !isset($_POST['account_id']) ||

$_POST['account_id'] == "" ) {

              echo "account_id is required.";
              exit;
      }

      // more stuff here...

      exec("/usr/bin/php -q /path/to/test2.php", $output); // should run

test2.php

      echo "<pre>";
      print_r($output);
      echo "</pre>";

http://www.example.com/test1.php Expected Result: Array (

    [0] => Hello, World!

) Actual Result: Array (

    [0] => X-Powered-By: PHP/5.2.1
    [1] => Content-type: text/html
    [2] =>
    [3] => account_id is required.

) Can anyone explain this and possibly help me find a solution? Thx, Brad P.S. I am posting a form to the test1.php page with a valid account_id etc.; after re-reading the message I thought someone might think it's printing that result because nothing is posted. Update: I also found a file called "error_log" in the folder where test2.php resides, full of several of these lines: [01-May-2007 14:12:52] PHP Warning: Zend Optimizer does not support this version of PHP - please upgrade to the latest version of Zend Optimizer in Unknown on line 0 Could that have something to do with why the script is calling on itself instead of running the specified php script? I recently had the hosting company rebuild PHP, first they did --enable-suexec (to run PHP as CGI) and then later rebuilt again to --enable-pcntl and --enable-sigchild, as I thought I would be needing that functionality. Did that break the CLI? Please help, Thx. Brad

It seems that the php binary isn't the same version as the php library used in the webserver and so that there's a problem loading Zend. Are you sure that the PHP binary is also replaced when they reinstalled PHP? Tijnema
