Description:
------------
When building daemon processes with php that requires the parent process to create a persistent database connection. The cleanup of the child process closes the parents database connection. A way to disable this cleanup on a object basis would make php better for daemon projects. This problem applies to other file descriptors aswell but the most problematic is the mysqli dblink resource.

Test script:
---------------
<?php

function query_db($dbo) {

        if(!mysqli_real_query($dbo, "SELECT 1"))
                die("Unable to query database: " . mysqli_error($dbo) . " (" . mysqli_errno($dbo) . ")\n");

        if(($res = mysqli_store_result($dbo)) === FALSE)
                die("Unable to store result: " . mysqli_error($dbo) . " (" . mysqli_errno($dbo) . ")\n");

        echo "Successful query\n";
}

$dbo = mysqli_init();
if (!mysqli_real_connect($dbo, 'dbserver', 'dbuser', 'dbpwd')) {
        die("Unable to connect to the database\n");
}

query_db($dbo);

$pid = pcntl_fork();
if ($pid == -1) {
        die("Could not fork\n");
} else if($pid) {
        // Parent
        pcntl_wait($status);
        query_db($dbo);
} else {
        // Child
        // mysqli_disable_cleanup($dbo, TRUE);
        exit(0);
}



Expected result:
----------------
Successful query
Successful query

Actual result:
--------------
Successful query
