Possible to break statement in foreach loop? - php

Question

I have two tables (user,user_group). Where user table contains
------------+-------------+------------------+
| user_id | user_name | user_group(id) |
------------+-------------+------------------+
and user_group table contains
+-----------------+-------------------+
| user_group_id | user_group_name |
+-----------------+-------------------+
Now I try to join them without using JOIN query. To solve this problem I have used double foreach() loop, but no result returns. I can't use break statement. How can I get the desired result using a loop? The desired result would be:
+-----------+-------------+-------------------+
| user_id | user_name | user_group_name |
+-----------+-------------+-------------------+
What I have so far:
public function user_get_item()
{
$this->db->select('*');
$this->db->from('users');
$results=$this->db->get()->result_array();
$this->db->select('*');
$this->db->from('user_group');
$group_data=$this->db->get()->result_array();
foreach($results as $v_results)
{
foreach($group_data as $v_group_data)
{
if($v_results['user_group']==$v_group_data['user_group_id'])
{
$v_results['user_group']=$v_group_data['user_group_name'];
}
}
}
return $results;
}

Answer 1

I think what you are trying to do is changing the group id identifier by the group name in the current row if they match. So, replace:
$results['user_group']=$v_group_data['user_group_name'];
by:
$v_results['user_group']=$v_group_data['user_group_name'];
Anyway, what's wrong with joins? Making SQL queries will be always faster than a polynomic loop.

Answer 2

Presumably you would have this:
Array(
0 => Array(
[user_id] => 1,
[user_name] => John Doe,
[user_group] => 200
),
1 => Array(
[user_id] => 2,
[user_name] => Jane Doe,
[user_group] => 100
)
)
And:
Array(
0 => Array(
[user_group_id] => 100,
[user_group_name] => Admin
),
1 => Array(
[user_group_id] => 200,
[user_group_name] => Web User
)
)
So make a new array for the group so it looks like this (ID as key, Name as value):
Array(
[100] => Admin,
[200] => Web User
)
To do that:
public function getUserGroups()
{
$rows = array();
$this->db->select('*');
$this->db->from('user_group');
$group_data=$this->db->get()->result_array();
foreach($group_data as $results)
{
$rows[$results['user_group_id']] = $results['user_group_name'];
}
return $rows;
}
Then you just assign in the other method:
public function userGetItem()
{
# Get all the user groups
$groupData = $this->getUserGroups();
# Get your original user list
$this->db->select('*');
$this->db->from('users');
$results=$this->db->get()->result_array();
$row = array();
foreach($results as $users) {
$row[] = array(
'user_id' => $users['user_id'],
'user_name' => $users['user_name'],
# Here you assign the group name from the user groups array
'user_group_name' => $groupData[$users['user_group']]
);
}
return $row;
}
Anyway, I think JOIN would be faster/better, but this should get you the results you are looking for, though I have not tested it, it should be close.
