storing db contents in array PHP - php

Question

I am not sure how to do this, but if it can be done can anyone please help me in this.
Basically I have 3 columns in my table:
ID Set Result Case
1 Set1 PASS 101
2 Set2 FAIL 102
3 Set2 FAIL 101
4 Set1 FAIL 101
5 Set1 PASS 104
$set = $row['Set'];
What I am trying to achieve is , foreach of these Set, store its associated Result and Case in an array.

Answer 1

$arr = array();
foreach ($records as $key => $value)
{
$arr[$key]['Result'] = $value['Result'];
$arr[$key]['Case'] = $value['Case'];
}
echo '<pre>';
print_r($arr);
echo '</pre>';
In light of your comment:
foreach ($records as $key => $value)
{
$arr[$key][$value['Result']] = $value['Case'];
}
In light of your most recent comment:
foreach ($records as $key => $value)
{
$arr[$value['Set']][$value['Result']] = $value['Case'];
}

Answer 2

After reading comments I thought I'd take a crack at it.
First of all: What you asking for will not work unless you are going to check for duplicate {result} keys in $array[Set2][{result}] and lowercase them if there are duplicates as in your comment, which I don't know why you'd do. It would be confusing and strikes me as nonsensical. To wit:
$arr[Set2][FAIL] vs. $arr[Set2][fail]
If you do it as shown above [in Alix Axel's third code block], you'll do:
$arr[Set2][FAIL] = 102 then overwrite that array index value with $arr[Set2][FAIL] = 101, causing you to lose data.
To put it another way, you are using a combination of the "set" and "result" as a "combined key" so to speak, which you CANNOT DO as the combinations are not unique (Set2 FAIL, Set2 FAIL). I know it's an annoying answer, but you should take a look at what you are doing and why, as I have a hunch you are going about it the wrong way. You probably want an array like:
Array
(
[Set1] => Array
(
[101] => 'FAIL'
[102] => 'PASS'
)
[Set2] => Array
(
[101] => 'FAIL'
[102] => 'FAIL'
)
)
or something, but even then it won't work as you have some Set/Case pairs both passing and failing. Because of this, the only thing you can do here is use the "id" as an index:
Array
(
[1] => Array
(
[Set] => 'Set1'
[Result] => 'PASS'
[Case] => '101'
)
[2] => Array
(
[Set] => 'Set1'
[Result] => 'FAIL'
[Case] => '101'
)
)
But I can't even tell you how to do that, cuz you haven't told us how your query results array is structured in the first place!! So step 1) Please print_r or var_dump the query results.

Answer 3

// assuming
$myArray = array();
$result = mysql_query("SELECT * FROM table ORDER BY Set ASC");
while ($rows = mysql_fetch_assoc($result)) {
for ($i = 0; $i <= count($rows); $i++) {
$myArray[$rows['ID']]['Set'] = $rows['Set'];
$myArray[$rows['ID']]['Result'] = $rows['Result'];
$myArray[$rows['ID']]['Case'] = $rows['Case'];
}
// output
Array
(
[1] => Array
(
[Set] => 'Set1'
[Result] => 'PASS'
[Case] => '101'
)
[2] => Array
(
[Set] => 'Set1'
[Result] => 'FAIL'
[Case] => '101'
)
[3] => Array
(
[Set] => 'Set1'
[Result] => 'PASS'
[Case] => '104'
)
[4] => Array
(
[Set] => 'Set2'
[Result] => 'FAIL'
[Case] => '102'
)
[5] => Array
(
[Set] => 'Set2'
[Result] => 'FAIL'
[Case] => '101'
)
)
