How to turn sql result to multi-dimensional array dynamically? - php

Question

Here is the query string.
$query = "SELECT t.id, t.assignee, t.owner,
d.code, d.status, d.target_completion_date,
d.target_extension_date, d.submission_date, d.approval_date,
d.revision_start_date, d.revision_completion_date, d.message,
ty.name, f.orig_name, f.new_name,
b.payment_date, b.discount, b.total_cost, b.amount_payed, b.edit_level,
b.billing_type, b.pages, b.words
FROM tasks t
INNER JOIN details d ON t.detail_id = d.id
INNER JOIN billing b ON t.billing_id = b.id
INNER JOIN TYPE ty ON d.document_type_id = ty.id
INNER JOIN files f ON t.file_id = f.id
WHERE t.assignee = 'argie1234'";
And this is the array i would like the query result to turn into.
$user = array('allTask'=>array(array('taskid' => 1,
'assignee'=>'argie1234',
'owner'=>'austral1000',
'details' => array( 'code' => 'E',
'status'=>'TC',
'targetCompletionDateUTC'=>'1379401200',
'targetExtentionDateUTC'=>'1379401200',
'submissionDateUTC'=>'1379401200',
'approvalDateUTC'=>'1379401200',
'revisionStartDateUTC'=>'1379401200',
'revisionCompletionDateUTC'=>'1379401200',
'messageToEditor'=>'Please work on it asap.',
'documentType' => 'Thesis'),
'file' => array('orig_name' =>'originalname.docx',
'new_name' => 'newname.docx'),
'billing'=>array('paymentDate'=>'July 26,2013 12:40',
'discount' => '0',
'totalRevisionCharge' => '$20.00',
'totalAmountPayed' => '$20.00',
'revisionLevel' => '1',
'chargeType'=> '1',
'numPages' => '60',
'numWords' => '120,000' ) ),
array('taskid' => 12,
'assignee'=>'argie1234',
'owner'=>'usaroberto',
'details' => array( 'code' => 'E',
'status'=>'TC',
'targetCompletionDateUTC'=>'1379401200',
'targetExtentionDateUTC'=>'1379401200',
'submissionDateUTC'=>'1379401200',

'new_name' => 'newname.docx'),
'billing'=>array('paymentDate'=>'July 26,2013 12:40',
'discount' => '0',
'totalRevisionCharge' => '$20.00',
'totalAmountPayed' => '$20.00',
'revisionLevel' => '1',
'chargeType'=> '1',
'numPages' => '60',
'numWords' => '120,000' ) ),
'account' => array( 'username' => 'marooon55',

How can i create the above array? I sure know how to define multi dimensional array, regretfully though i am having difficulty creating this complex array dynamically. As a beginner i don't even know where to begin.

Answer 1

Here is an example that might help you out. Try starting with simple multi dimensional arrays, once you get a hold of it, you can move onto building complex ones. You will then find that the array you want to build is not really difficult than you initially thought it to be.
$mycomplexarray = array('key1' => array('val1', 'val2'),
'key2' => array('val3', 'val4' => array('val5', 'val6')
)
);

Answer 2

You could create the array just as you have here. I'm not gonna write the whole thing out, but something like this...
$result = $mysqli->query($query); // however you query the db is up to you.
$row = $result->fetch_assoc(); //same as query use your prefered method to fetch
$user = array('allTask'=>array(array('taskid' => $row['id'],
'assignee'=>$row['assignee'],
'owner'=>$row['owner'],
'details' => array( 'code' => $row['code'],
'status'=>$row['status'],
...etc, Hope this makes sense for you.

Answer 3

Set up a structure array first that defines which columns will be stored in a sub array like
$struc=array('Id'->0, 'assignee'->0, 'owner'->0,
'code'->'detail', 'status'->'detail', 'target_completion_date'->'detail',
'target_extension_date'->'detail', 'submission_date'->'detail', 'approval_date'->'detail',
'revision_start_date'->'detail', 'revision_completion_date'->'detail', 'message'->'detail',
'name'->'file', 'orig_name'->'file', 'new_name'->'file',
'payment_date'->'billing', 'discount'->'billing', 'total_cost'->'billing', 'amount_payed'->'billing', 'edit_level'->'billing', 'billing_type'->'billing', 'words');
In your while ($a=mysqli_fetch_assoc($res)) loop you can now use this structure to decide whether you want to store an element directly in your target array or whether you want to place it in the subarray named in this structure array. Like
$res=mysqli_query($con,$sql);
$arr=array();
while($a=mysqli_fetch_assoc($res)) {
// within result loop: $a is result from mysqli_fetch_assoc()
$ta=array(); // temp array ...
foreach ($a as $k => $v){
if ($struc[$k]) $ta[struc[$k]][$k]=$v;
else $ta[$k]=$v;
}
$arr[]=$ta; // add to target array
}
This is the complete code, no more is needed. It was typed up on my iPod, so it is NOT tested yet.
The generated array should be equivalent to your $user['allTask'] array.
