How to get all values from a database column - php

Question

I have a basic system I am creating in which a user creates goals. When the goal is inserted, it is given a value of 0 to the status column. When the goal is completed, the value is updated to 1. So, what I am trying to do is fetch the specific user's (user with the current session) total number of ids (rows for the amount of goals) and then get the values of the status column and then count those. Once the actual status column values have been added, I want to divide that by the total number of id's. I am basically trying to figure out how to get a rate of completion.
I am not certain how I can:
-count the number of total id's for the user.
-get the values of the status column for the user and then add those.
Can anyone point me in the right direction?
Table
Create Table
goals
CREATE TABLE `goals` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`title` text COLLATE utf8_unicode_ci NOT NULL,
`description` text COLLATE utf8_unicode_ci NOT NULL,
`status` int(5) NOT NULL,
`importance` int(5) NOT NULL,
`date` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_c
$select_goals_sql = "
SELECT *
FROM goals
WHERE user_id = ?
ORDER BY id DESC
";
if ($select_goals_stmt = $con->prepare($select_goals_sql)) {
$select_goals_stmt->execute(array($user_id));
$rows = $select_goals_stmt->fetchAll(PDO::FETCH_ASSOC);
$goals = array();
foreach ($rows as $row) {
$goal_date = $row['date'];
$fixed_goal_date = fixDate($goal_date);
// the varialbe I will name it $status_completed =
$html = "";
Edit:
$goal_total_sql = "
SELECT sum(status) as sumna,
COUNT(*) as cnt
FROM goals
WHERE user_id = ?
";
if ($goal_total_stmt = $con->prepare($goal_total_sql)) {
$goal_total_stmt->execute(array($user_id));
$rows = $goal_total_stmt->fetchAll(PDO::FETCH_ASSOC);
foreach ($rows as $row) {
$actual_status = $row['status'];
$total_status = $row['id'];
}
}
?>
<div id="main">
<?php
echo "Actual:". $actual_status;
echo "Total". $total_status;
?>

Answer 1

SELECT status_id FROM goals WHERE userId = ? GROUP BY status_id should count the number of ids for each state

Answer 2

SELECT COUNT(*) as goal_count, status FROM goals WHERE user_id = ? GROUP BY status;
This will show you in tabular format the goal_count next to the status.
here is a sqlfiddle:

so using a modified version of your create table (You should be using Innodb and I ommited the Collac for simplicity)
your result should be like this:
+------------+--------+
| goal_count | status |
+------------+--------+
| 1 | 1 |
| 2 | 2 |
| 2 | 3 |
| 2 | 4 |
+------------+--------+

Answer 3

I's hard to tell what you need here because the question title contradicts with body and both with code provided. But as far as I can tell
SELECT sum(status) as summa, COUNT(*) as cnt FROM ...
