Update a mysql table based on another. Complicated query - php

Question

Short about my tables: I have 2 tables: content, users
content structure is something like:
id | title | cpc | user | active
users is:
id | user | monetos
Idea - I want to select contet.* rows which have content.active = 1 (n). Having this data, SELECT users.monetos WHERE users.id=content.user from previous query.
And now, by maximum (n) steps i decrement users.monetos value by content.cpc value
and on the moment when *users.monetos=0 or less than 0, i want to update content and SET active='0'*
By words, i want like to share users.monetos amount to each content entry (content.cpc for each). And there's no more users.monetos make the current content
entry inactive. And do this vor every content.user
What i'he done at this moment is shown below. I now it looks really bad, but i already don't know what to do. Count on you guys. Thank you.
$kak2 = array();
$rs16 = $connector->query("SELECT user FROM content WHERE active='1'");
while($rw16 = $connector->fetchArray($rs16))
{
$users_ids[] = $rw16['user'];
}
$user_info2 = $connector->fetchArray("SELECT monetos,id FROM users WHERE id IN (".implode(',',$users_ids).")");
while($user_info = $connector->fetchArray($user_info2))
{
$current_entry_info2 = $connector->query("SELECT cpc,id FROM content WHERE user='$user_info[id]' ORDER BY date DESC");
while ($current_entry_info = $connector->fetchArray($current_entry_info2))
{
$user_info['monetos']= $user_info['monetos'] - $current_entry_info['cpc'];
if($user_info['monetos'] = 0)
{
$updt = $connector->query("UPDATE content SET active='0' WHERE id='$current_entry_info[id]' LIMIT 1");
}
}
}

I think i have got the idea of what you are trying to do so have contructed a small code snippit which i think should do what you are after.
note this is untested code
/** get the cost of all content for all users **/
$query = "select b.id, sum(a.cpc) as cpc from content a
join users b on a.user= b.id
group by b.id where a.active = 1"
/** cycle each user **/
foreach($rows = $connector->fetchArray($query) as $row ) {
$menotos = $row['cpc'];
$query = "select id, cpc from content where user={$row['id']}"
/** cycle each users content **/
foreach($contents = $connector->fetchArray($query) as $content) {
$menotos -= $content['cpc'];
if($menotos <= 0) {
$disable[] = $content['id'];
}
}
if( isset($disable) ) {
$connector->query("update content set active=0 where id in(" . implode(',', $disable) . ")";
}
}
