How to get rsync progress using proc_open?

Question

linux

Good afternoon. Trying to catch rsync progress when executing php command "proc_open"

$query = "rsync --bwlimit=20000 --delete --chmod=ugo=rwX --modify-window=5 -rlpgoD --contimeout=3600 '$client_root/$src' --exclude=*/en_us/client/sandbox --info=progress2 --no-i-r --exclude=*/en_us/server/sandbox  $host::drive_$drive_letter/$path";
    $descriptors = array(
        0 => array("pipe", "r"),
    );
    $proc = proc_open($query, $descriptors, $pipes);
    $exitCode = proc_close($proc);

It gives progress on the output, but I can’t catch it in order to withdraw

Tell me how to catch it?
