shell_exec how to pass arrays

Question

I want to pass parameters in a file that will run background in order to send emails.

shell_exec("php /path/to/the/background/script.php '$arrayObjects' > /dev/null &");

When I var_dump the parameter $arrayObjects I get as output

Array

actually it is passed as string.

Does someone know how to pass arrays?

Answer 1

php shell_exec is a command line interface so it can only accept strings as arguments.

if you haven't solved it yet then maybe you can use foreach loop to execute mail script for each mail.

try this:

$emails = array ( 
          // list of emails
          );

foreach( $emails as $email ) {
    shell_exec("php /path/to/the/background/script.php '$email["email"]' > /dev/null &");
}

Hope this helps.
