The problem is to get the following result set:
'org1', 'unit1', 'proj1'
'org1', 'unit1', 'proj2'
'org1', 'unit2', 'proj1'
'org1', 'unit2', 'proj2'
'org2', 'unit1', 'proj1'
'org2', 'unit1', 'proj2'
to the following in php:
[{"units": [{"name": "unit1", "projects": ["project1", "project2"]}, {"name": "unit2", "projects": ["project1", "project2"]}], "name": "org1"}, {"units": [{"name": "unit1", "projects": ["project1", "project2"]}], "name": "org2"}]
Any suggestions?
You can use something like
$final_array = array();
foreach($array as $row){
$final_array[$row[0]][$row[1]][] = $row[2];
}
Now this will "convert the SQL result array into a multidimentional array/tree" but not like what you want yet.
So we shall have to process the array again..
$final_array_2 = array(); // Lets go deep
foreach ($final_array as $name => $units) {
$quarterfinal_array = array(); // Not deep enough
$semi_final_array = array();
foreach ($units as $proj_name => $projects) {
$nano_final_array = array(); // Lets dig deeper ;)
$nano_final_array['name'] = $proj_name;
$nano_final_array['projects'] = $projects;
$semi_final_array[] = $nano_final_array;
}
$quarterfinal_array['units'] = $semi_final_array;
$quarterfinal_array['name'] = $name;
$final_array_2[] = $quarterfinal_array;
}
echo json_encode($final_array_2);
PS: Sorry my choice of variable names are not the most ideal, but they get the work done ;) This is a P.O.C, You can always improve on it.

Laravel Version:7.0
I would like to know how to create this helper.
Input is date range array. For example:
$input1 = [2020-07-19, 2020-07-25];
$input2 = [2020-07-26, 2020-08-01];
$input3 = [2020-08-01, 2020-08-07];
$input4 = [2020-10-01, 2020-10-07];
$input5 = [2020-10-19, 2020-10-25];
I would like to make one helper function.
function mergeDate($array)
{
...
}
So when I use this helper, I would like to get as following result.
$array = [$input1, $input2, $input3, $input4, $input5];
$mergedResult = mergeDate($array);
$mergedResult[0] = [2020-07-19, 2020-08-07];
$mergedResult[1] = [2020-10-01, 2020-10-07];
$mergedResult[2] = [2020-10-19, 2020-10-25];
Can anyone help me how to make mergeDate function?
Input period elements aren't overlapped.
Thank you!
This would be my first guess at how to solve it.
public function merge($array){
$results = [];
foreach ($array as $element){
if (sizeof($results) == 0){
array_push($results,$element);
}else{
$found = null;
foreach ($results as $key => $r){
if (Carbon::parse($element[0])->equalTo(Carbon::parse($r[1])))
{
$found = $key;
break;
}
}
if (!is_null($found)){
$results[$found][1] = $element[1];
}else{
array_push($results, $element);
}
}
}
return $results;
}
It is a simple take on the problem. If our resulting array is empty we add the first element otherwise we iterate over the results to find a matching pair of the elements end date and the start date of the item in the results array. If we find a matching start end pair we replace the results end value with the elements end value. Otherwise we have no overlap and we can add it as a new item to the results array.
An interesting library to use would be the Spatie/Period library.

#edit
since the array is not sorted as mentioned in a comment above, you would have to sort it prior.

Need a sanity check on this one, I think I just confused myself. I am trying to loop throught the below array and get the fields back for multiple people that are register.
{
[12]=>
array(79) {
["Event Number"]=> int(466226)
["Event Info"]=> string(134) “Event ABC”
["Event Acct Code"]=> NULL
["email"] => string(12)"email#email.com
}
}
How can i best accomplish this?
This is what I tried
$associativeEventInfo=[];
foreach ($res as $eventInfo)
{
$associativeEventInfo[]=$eventInfo;
}
var dumping $associativeEventInfo returns the results
Id like to get each field out according to the array, for example
["EvenNumber"] =466226 so that I can then pass that over to database and do stuff.
So the goal is to remap the data to presumably database fields. First off, accessing the fields is quite easy:
// Assuming $returnedData is an array of assoc array containing the data;
foreach ($returnedData as $eventData)
{
$eventNumber = $eventData['Event Number'];
$eventInfo = $eventData['Event Info'];
// And so on
}
Remapping it is as simple as creating a new array with the correct format (one can also use array_map but I leave that as a readers exercise):
$remappedData = [];
// Assuming $returnedData is an array of assoc array containing the data;
foreach ($returnedData as $eventData)
{
$remappedData[] = [
'eventNumber' => $eventData['Event Number'],
'eventInfo' => $eventData['Event Info'],
// And so on
];
$eventNumber = $eventData['Event Number'];
$eventInfo = $eventData['Event Info'];
}

How i can combine ad array of values into an array with double combination string without duplications ?
For example, if i have something like:
array('one','two','tre','four','five');
I want to obtain an array of combinations like this ('one / two') just one time and not also ('two / one').
In this way i wanto to get something similar to:
array('one/two', 'one/tre', 'one/four', 'one/five', 'two/tree','two/four' .......
Suggestions ?
You can do it with this code. It won't show two/one, three/two, etc (that's how I understood it):
<?php
$array = array('one','two','tre','four','five');
$newArray = [];
foreach ($array as $el) {
foreach ($array as $el2) {
if ($el === $el2) continue;
$newArray[] = $el."/".$el2;
}
array_shift($array); // remove the element we just went through
}
print_r($newArray);

I have a complicated JSON and I need create array from this JSON.
I already parsed JSON and create a variablies like this:
$name = $json[response][docs][$i][name][0];
$osm_id = $json[response][docs][$i][osm_id][0];
$place = $json[response][docs][$i][place][0];
$population= $json[response][docs][$i][population][0];
now I need a array, with this variablies, where the $i is changing, like this:
$array = [array_1(name,osm_id,place,population),array_2(name_2,osm_id_2)]
Can you help me with the cycle to fill this array?
If my understanding is correct,
$expected_arr = array();
foreach($json[response][docs] as $inc => $values){
$data = array();
foreach($values as $key => $val){
$data[$key] = $val[0];
}
$expected_arr[$inc] = $data;
}
So you would get something like
array(0 => array( 'name'=>'xxx', 'osm_id'=>'yy',..), 1=> array('name'=>'',.. ,),...)

Sorry for my english..
in mysql has row name iurl.. There is data: 1365269423.jpg,1365270586.jpg,1365270666.jpg,1365270683.jpg
i get its as:
<?php $s=mysql_query("select iurl from points where id='".$_GET['id']."' ");
if($s){
$array = array();
while($t=mysql_fetch_array($s)) {
$array[] = $t['iurl'];
}
print_r($array);
?>
it gives me result: Array ( [0] => 1365269423.jpg,1365270586.jpg,1365270666.jpg,1365270683.jpg )
And i`m need get it and print like a link
how can i do it?
Thanks..
You can use explode(); to split the string into an array and then loop over to print each item:
$images = explode(",", $t["iurl"]);
foreach ($images as $image) {
echo "{$image}";
}
I think you are asking to have result or in your case a .jpg file be the href of your link? If so do this:
......
The result you get from your database as you already figured out is an Array
The only thing you need to do is loop trough the array.
ps: consider using mysqli more info at php.net http://www.php.net/manual/en/book.mysqli.php
<?php
$s=mysql_query("select iurl from points where id='".$_GET['id']."' ");
while ($row = mysql_fetch_object($s)) {
echo '<img="http://yourhost.com/images/'.$row->image.' alt=""/>';
}
?>
