how to get all datas in a mysql table with same id - php

Question

I have something like that in my mySQL database:
(User 734 have many informations : biography, name, phone, mail ...)
I want to get an array (in PHP) with grouped datas :
array(
[734]=>
object {
[155] => string "Dominique",
[4] => int(047682037),
[1] => string "Dominique B"
},
[735]=>
object {
[155] => string "Other",
[4] => int(0123456789),
[1] => string "Other B"
}
)
not only for 734 user but for each user. With a simple query I get everything but not in the good order. Can I make it in SQL or I maybe need to rearrange datas in PHP next ?
What is the sql query to get, for each user_id, all the related datas ?
I can't change the database structure (WP and buddypress)
I can't use native WP functions (because getting datas from another site)

Answer 1

SELECT * FROM (whatever your table name is)
WHERE user_id = (whatever user id you're interested in getting data for)

Answer 2

Solution using ORDER BY :
$users = array();
$current_user = null;
$result = $mysqli->query("SELECT user_id, field_id, value FROM `TABLE_NAME` ORDER BY user_id, field_id");
while ($result && $row = $mysqli->fetch_assoc($result)) {
if ($current_user != $row['user_id']) {
$current_user = $row['user_id'];
$users[$row['user_id']] = array();
}
$users[$row['user_id']][$row['field_id']] = $row['value'];
}
EDIT :
There is another solution using GROUP BY and GROUP_CONCAT :
$users = array();
$result = $mysqli->query("SELECT user_id, GROUP_CONCAT(field_id SEPARATOR '|') as fields, GROUP_CONCAT(value SEPARATOR '|') as values FROM `TABLE_NAME` GROUP BY user_id");
while ($result && $row = $mysqli->fetch_assoc($result)) {
$fields = explode('|', $row['fields']);
$values = explode('|', $row['values']);
$users[$row['user_id']] = array();
// Problem id you have your field ids and your values in separate arrays, not sure what you want to do with them
}

Answer 3

$result = mysqli_query($con, "SELECT * FROM table_name WHERE user_id = 734");
Or if you arent using mysqli:
$result = mysql_query("SELECT * FROM table_name WHERE user_id = 734");

If you are using the PDO library you could check the PDO::FETCH_GROUP attribute.
http://php.net/manual/en/pdostatement.fetchall.php
fetch_style:
To return an associative array grouped by the values of a specified column, bitwise-OR PDO::FETCH_COLUMN with PDO::FETCH_GROUP.

Answer 5

$stmt = $this->_mysqli->prepare('SELECT user_id,field_id,value FROM WHERE user_id = ?');
$stmt->bind_param('i', $user_id );
$stmt->execute();
$stmt->bind_result($user_id, $field_id, $value);
while($stmt->fetch())
{
$data[$user_id][$field_id] = $value;
}
