How can I run PHP code asynchronously without waiting? I have a long run (almost infinite) that should run while server starts and should process asynchronously without waiting.

The possible options I guess are:

  1. Running the code in a web page and keep it open to do that task
  2. Calling the script from some command line utility (I am not sure how) which would process in the background.

I am running the PHP scripts on my local server which will send emails when certain events occur, e.g. birthday reminders.

Please suggest how can I achieve this without opening the page in a browser.



If you wanted to run it from the browser (perhaps you're not familiar with the command line) you could still do it. I researched many solutions for this a few months ago and the most reliable and simplest to implement was the following from How to post an asynchronous HTTP request in PHP


$params['my_param'] = $a_value;
post_async('http:://localhost/batch/myjob.php', $params);

 * Executes a PHP page asynchronously so the current page does not have to wait for it to     finish running.
function post_async($url, array $params)
    foreach ($params as $key => &$val) {
      if (is_array($val)) $val = implode(',', $val);
        $post_params[] = $key.'='.urlencode($val);  
    $post_string = implode('&', $post_params);


    $fp = fsockopen($parts['host'],
        $errno, $errstr, 30);

    $out = "POST ".$parts['path']." HTTP/1.1rn";
    $out.= "Host: ".$parts['host']."rn";
    $out.= "Content-Type: application/x-www-form-urlencodedrn";
    $out.= "Content-Length: ".strlen($post_string)."rn";
    $out.= "Connection: Closernrn";
    if (isset($post_string)) $out.= $post_string;

    fwrite($fp, $out);

Let's say the file above is in your web root directory (/var/www) for example and is called runjobs.php. By visiting http://localhost/runjobs.php your myjob.php file would start to run. You'd probably want to add some output to the browser to let you know it was submitted successfully and it wouldn't hurt to add some security if your web server is open to the rest of the world. One nice thing about this solution if you add some security is that you can start the job anywhere you can find a browser.

I had the same issue recently. It appears to be an issue with PHP garbage collection. Disabling garbage collection during phpunit runs solved the problem to me.



to your php.ini file or from the command line with:

phpunit -d zend.enable_gc=0

You should point to your vendor/autoload.php at Settings | PHP | PHPUnit when using PHPUnit via Composer.

This blog post has all the details (with pictures) to successfully configure IDE for such scenario:

On Mac OS X environment variables available in Terminal and for the normal applications can be different, check the related question for the solution how to make them similar.

Note that this solution will not work on Mountain Lion (10.8).

Under Windows it seems that files in vendor/bin are actually batch files, invoking the original file (and not php files which phpdbg will understand).

In this case:

dir=$(d=${0%[/\]*}; cd "$d"; cd "../phpunit/phpunit" && pwd)
"${dir}/phpunit" "$@"

i.e. ../phpunit/phpunit/phpunit (this path is relative to vendor/bin); thus the actual file is at vendor/phpunit/phpunit/phpunit.

And you can invoke it directly via phpdbg -qrr vendor/phpunit/phpunit/phpunit then.
