curl发布到包含sleep（）函数的php文件

Question

I want to send an email with automatted content from a login script, but it should be sent with a delay of some (randomized) seconds (for sending one part of a key pair).

Thats why I was trying to use curl, which generally works, instead of using "include" or a class, but the main script should not have to wait until sleep() is ended.

main code is (simple curl code) playing around with "CURLOPT_MUTE,1" and "CURLOPT_RETURNTRANSFER,false" did not work at all.

    <?php
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"http://domain/path/to/delayed_mail.php");
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,
        'to=' . $to . '&from=' . $from . '&subject=...');
    curl_exec ($ch);
    curl_close ($ch);
    ?>

delayed_mail.php looks something like this

    <?php
    //path to mail class
    //some POST and GET REQUEST filters and authentications
    //with      $_REQ[$key]=$value;   as output

    $delay = rand(2,32);
    sleep($delay);
    $ddlab->mail->html($_REQ['to'],$_REQ['from'],...,$_REQ['options']);
    ?>

As I mentioned above, I got stuck a bit. The main script which is for html output, shall not wait, until email is sent, after sleep().

1st question: How "delayed_mail.php" can be executed independent (Send email whenever you want to do so, but leave my script running!)

2nd question: How can I set an internal path like '../../delayed_mail.php' or getcwd().'/delayed_mail.php' (which both doesn´t seem to work) instead of full "http://"-URL ?

Thanks for your efforts.

Answer 1

YES I want to answer my question :-)

The solution is, NOT to use curl at all :-), thanks to Martin Lakes´s post at http://php.net/manual/en/function.exec.php I used a Linux command. For Windows based servers it must look different, but there´s not enough space on here ;-)

    <?php
    passthru("
        /usr/bin/php
        /home/www/path/to/delayed_mail.php
        " . $params . "
        >
        /home/www/path/to/delayed_mail.log
        2>&1
        &
        ");
    ?>

which is explained here:

    <?php
    passthru("
        linux_php_call
        executed_file
        transferred_parameters
        linux_command_for_output 
        output_file
        linux_commands
        ampersand_at_the_end_for_silent_mode
        ");
    ?>

(All parameters queued with a space)

Just put all required parameters into $params, e.g. as an array(), you´ll get it as a key of $argv, which is an array() too and here you are.
