Search nested multidimensional array - php

Question

I have a function that fills an array:
foreach ($request->get('ids') as $id) {
$pdfArray['other']++; // Yes this is initialized
$pdfArray['rows'][$i]['id'] = $schedule->getId();
$pdfArray['rows'][$i]['date'] = $schedule->getStart()->format('d.m.Y');
$pdfArray['rows'][$i]['dateSort'] = $schedule->getStart()->format('Y-m-d H:i');
$pdfArray['rows'][$i]['from'] = $schedule->getStart()->format('H:i');
$pdfArray['rows'][$i]['to'] = $schedule->getEnd()->format('H:i');
$pdfArray['rows'][$i]['desc'] = $schedule->getDescription();
}
What I want to do
On each loop, I want to check if the array (so far) already has a desc entry equal to the current $schedule->getDescription() AND the same date as $schedule->getStart()->format('d.m.Y') (actually more, but let's keep it simple)
What I tried
public function recursive_array_search($needle,$haystack) {
foreach($haystack as $key=>$value) {
$current_key=$key;
if($needle===$value OR (is_array($value) && $this->recursive_array_search($needle,$value) !== false)) {
return $current_key;
}
}
return false;
}

I use it like that:
if ($this->recursive_array_search($schedule->getDescription(), $pdfArray['rows']) &&
$this->recursive_array_search($schedule->getStart()->format('d.m.Y'), $pdfArray['rows'])){
$pdfArray['ma'][$schedule->getId()]++;
}
but this is true when ANY of the start or desc are SOMEWHERE in the current array.
How would I check if desc is found and start is in the SAME $i level?
EDIT for example
Let's say I have 10 $ids to loop through. After 2 loops, the $pdfArray looks like this:
Array
(
[other] => 2
[rows] => Array
(
[0] => Array
(
[id] => 1
[date] => 13.07.2016
[dateSort] => 2016-07-13 08:00
[from] => 08:00
[to] => 09:00
[desc] => TEST
)
[1] => Array
(
[id] => 2
[date] => 12.07.2016
[dateSort] => 2016-07-12 08:00
[from] => 08:00
[to] => 09:00
[desc] => TEST
)
)
)
The next iteration has the following:
$schedule->getStart()->format('d.m.Y') => 12.07.2016
$schedule->getDescription() => TEST
So I want to have the info that the combination already exists in the array.
BUT
$schedule->getStart()->format('d.m.Y') => 12.07.2016
$schedule->getDescription() => TEST2
should NOT return true upon checking of it exists.

Answer 1

To test for a "duplicate" you can use this function:
function testPresence($pdfArray, $desc, $date) {
foreach ($pdfArray["rows"] as $row) {
if ($row["desc"] == $desc && $row["date"] == $date) return true;
}
}
Example use:
echo testPresence($pdfArray, "TEST2", "12.07.2016") ? "Found" : "Not found"; // Not found
echo testPresence($pdfArray, "TEST", "12.07.2016") ? "Found" : "Not found"; // Found
In your original loop, you can use it as follows:
foreach ($request->get('ids') as $id) {
if (testPresence($pdfArray, $schedule->getDescription(),
$schedule->getStart()->format('d.m.Y')) {
// We have a duplicate. Maybe skip this entry?:
continue;
}
$pdfArray['other']++;
$pdfArray['rows'][$i]['id'] = $schedule->getId();
$pdfArray['rows'][$i]['date'] = $schedule->getStart()->format('d.m.Y');
$pdfArray['rows'][$i]['dateSort'] = $schedule->getStart()->format('Y-m-d H:i');
$pdfArray['rows'][$i]['from'] = $schedule->getStart()->format('H:i');
$pdfArray['rows'][$i]['to'] = $schedule->getEnd()->format('H:i');
$pdfArray['rows'][$i]['desc'] = $schedule->getDescription();
}

Answer 2

try this at your validation function
public function array_search($needle1, $needle2 ,$haystack) {
foreach($haystack as $singleArray){
if (in_array($needle1, $singleArray) && in_array($needle2, $singleArray))
return true;
else
continue;
}
return false;
}
and invoke your recursive_array_search like this
if ($this->array_search($schedule->getStart(), $schedule->getDescription(), $pdfArray['rows'])
continue;//Or any other kind of logic you want. At this place you know that description and date staet exist in at your array level
$pdfArray['other']++; // Yes this is initialized
$pdfArray['rows'][$i]['id'] = $schedule->getId();
$pdfArray['rows'][$i]['date'] = $schedule->getStart()->format('d.m.Y');
$pdfArray['rows'][$i]['dateSort'] = $schedule->getStart()->format('Y-m-d H:i');
$pdfArray['rows'][$i]['from'] = $schedule->getStart()->format('H:i');
$pdfArray['rows'][$i]['to'] = $schedule->getEnd()->format('H:i');
$pdfArray['rows'][$i]['desc'] = $schedule->getDescription();

Answer 3

Function version:
/**
* Find matches for $item into pdfArray.
* Returns an index array, possibly empty if no matches.
* #param $item item to find
* #param $rows rows where to search
*/
function findPdfArrayMatches(array $item, array $rows) {
return array_keys(
array_filter(
$rows,
function ($entry) use ($item) {
// These are the matching criteria. More than one row may match.
return $entry['desc'] == $item['desc']
&& $entry['date'] == $item['date']
;
}
)
);
}
You could do like this, in the loop:
$item = [
'id' => $schedule->getId(),
'date' => $schedule->getStart()->format('d.m.Y'),
'dateSort' => $schedule->getStart()->format('Y-m-d H:i'),
'from' => $schedule->getStart()->format('H:i'),
'to' => $schedule->getEnd()->format('H:i'),
'desc' => $schedule->getDescription(),
];
$matches = findPdfArrayMatches($item, $pdfArray['rows']);
if (!empty($matches)) {
...do something with the matches:
foreach ($matches as $match) {
$pdfArray['rows'][$match]['Duplicate'] = true;
}
}
// Add new item
$pdfArray['rows'][$i] = $item;
