Hi I have a problem regarding multi-dimension array. I have a set of array looking like this
array:3 [▼
0 => array:1 [▼
"tree" => "0"
]
1 => array:1 [▼
"tree" => "2"
]
2 => array:1 [▼
"tree" => "0"
]
]
the array is from
dd($this->treeArray);
how do I want to get the array which the value is 0. Expected result/filter
For example:
array:2 [▼
0 => array:1 [▼
"tree" => "0"
]
1 => array:1 [▼
"tree" => "0"
]
]
or
array:1 [▼
0 => array:1 [▼
"tree" => "2"
]
]
if changing the index is impossible, its ok..
Thank you
As you are using Laravel, you could use array helper such as this
You can use like this:
use Illuminate\Support\Arr;
$newTreeArray = Arr::where($this->treeArray, function ($tree) => $tree['tree'] === "0");
do you want in_array()?
$arraysContainingZero=[];
foreach($this->treeArray as $wutkey => $wut){
if(in_array("0", $wut, true)){
$arraysContainingZero[$wutkey] = $wut;
}
}
var_dump($arraysContainingZero);
There are a lots of build in function in PHP that is useful for operating on an array. You can see the full list here: https://www.php.net/manual/en/ref.array.php
One of the function is called array_filter (https://www.php.net/manual/en/function.array-filter.php). The function iterates over each value in the array passing them to the callback function. If the callback function returns true, the current value from array is returned into the result array.
So in your case, you want to call the array_filter with a callback that return true if the value is 0. Example:
$input = [
[ 'tree' => 1 ],
[ 'tree' => 0 ],
[ 'tree' => 0 ],
];
$output = array_filter($input, function($arr) {
return $arr['tree'] === 0;
});
var_dump($output);
// result
array(2) {
[1]=>
array(1) {
["tree"]=>
int(0)
}
[2]=>
array(1) {
["tree"]=>
int(0)
}
}
php unset is working but on reload the session data is still there:
I'm building simple addtocart and remove from cart in php/symfony5, but I'm unable to unset the array from multi dimension array in symfony session.
^ array:3 [▼
0 => array:1 [▼
"items" => array:4 [▼
0 => 9
1 => "Dry fruit"
2 => "1234"
3 => "250g"
]
]
1 => array:1 [▼
"items" => array:4 [▼
0 => 8
1 => "Pumpkin"
2 => "123"
3 => "x"
]
]
This is my cart controller:
$basket = $session->get('basket',[]);
dump($basket);
$size = $session->get('size');
if($request->isMethod('POST')){
$id = $request->request->get('0');
foreach($basket as $key => $value){
if($value['items'][0] == $id){
unset($basket[$key]['items']);
dd($basket);
//$session->set('basket',[]);
//return $this->redirectToRoute('cart');
}
}
}
On the above code when I click remove button in twig and when dd($basket) is done the array is empty like below:
^ array:3 [▼
0 => [] //empty
1 => array:1 [▼
"items" => array:4 [▼
0 => 8
1 => "Pumpkin"
2 => "123"
3 => "x"
]
]
But, when I comment dd($basket) and page is reloaded the array is as it is like before(seems reverted idk) and if I uncomment $session->set('basket',[]); everything is empty.
what I want to achieve here is, how to remove array from session multi dimension array?
You simply need to set the session variable to the updated $basket value.
// get a copy of the basket from the session
$basket = $session->get('basket',[]);
// do whatever to update $basket here
// overwrite the basket in the session
$session->set('basket', $basket);
// then return a Response
My aim here is to remove the whole object from the array if "record_type" is null. I should then only be left with data that has a record_type set in the array.
I've looked into the array filter not sure how I target the data within the array "record_type". My only other thought is to import to a database and then SQL query what I want then delete data I've had which is much more overkill.

Goal: only be left with data that has a 'record_type' set (not null) in the array
Solution: use array_filter() on your source array ($arr) and filter for records with 'record_type' != "NS" (assuming "NS" is what you refer to as null, or not set).
<?php
$result = array_filter(
$arr,
function (array $record) {
if (isset($record['record_type'])) {
return $record['record_type'] != "NS";
} return null;
}
);
working demo
EDIT
If you want to filter for only those records that are of a certain type, e.g. type 'record', following should help:
<?php
$result = array_filter(
$arr,
function (array $record) {
if ($record['type'] == 'record') {
return true;
} return false;
}
);
working demo
If your Goal is to filter array to remove any inner-array that hasn't a record_type, So use array_filter with a callback function fn to check that record_type exist with isset function.
array_filter($arr, fn($el)=>isset($el["record_type"]));
I have an array:
array:8 [▼
0 => array:1 [▼
"data" => "789"
]
1 => array:1 [▼
"data" => "800"
]
2 => array:1 [▼
"data" => "789"
]
3 => array:1 [▼
"data" => "787"
]
4 => array:1 [▼
"data" => "787"
]
5 => array:1 [▼
"data" => "787"
]
6 => array:1 [▼
"data" => "787"
]
7 => array:1 [▼
"data" => "787"
]
]
I need to take out the last 2 elements of the array and compare them. I tried using $getLast2 = array_slice($chart_data, -2, 2, true); to get the last 2.
array:2 [▼
6 => array:1 [▼
"data" => "787"
]
7 => array:1 [▼
"data" => "787"
]
]
Which then splits it. But Im not sure how to compare these 2 elements within this new array. As the last 2 elements which are now 6 and 7 could change as more data is added. I basically need to tell if the first element is great than, less than or equal to the second element.
You can use built in end() function and then prev():
if (end($chart_data) == prev($chart_data)) {
echo 'Two last elements of an array are equal!';
}
Pass last variable as false;
preserve_keys
Note that array_slice() will reorder and reset the numeric array indices by default. You can change this behaviour by setting preserve_keys to TRUE.
array_slice($chart_data, -2, 2, false);
You have output this array
array:2 [▼
6 => array:1 [▼
"data" => "787"
]
7 => array:1 [▼
"data" => "787"
]
]
Re-index them to using PHP array_values() function
$outputedArray = array_values($outputedArray)
if($outputedArray[0]['data'] > $outputedArray[1]['data'])
echo "0 index is greater";
If the array you obtained from your previous code is called $splitArray, then you could do the following:
list($array1, $array2) = $splitArray;
if ($array1['data']>$array2['data'])
{
echo "1st is greater than 2nd<br>";
}
else
{
echo "1st is not greater than 2nd<br>";
}
If it suits you, you can just use the array_pop to do the comparison in this manner:
<?php
$array = [
["data" => "789"],
["data" => "800"],
["data" => "789"],
["data" => "787"],
["data" => "787"],
["data" => "789"],
["data" => "787"],
["data" => "787"],
];
// MAKE A COPY OF THE ORIGINAL ARRAY:
$arrayCopy = $array;
// POP THE LAST ELEMENT OFF THE $arrayCopy AND SAVE IT AS $lastElem:
$lastElem = array_pop($arrayCopy);
// POP THE LAST ELEMENT OFF THE $arrayCopy AGAIN AND SAVE IT AS $beforeLastElem:
$beforeLastElem = array_pop($arrayCopy);
// NOW YOU CAN COMPARE THE LAST ELEMENT AND THE ONE BEFORE IT
if($lastElem == $beforeLastElem){
echo "The last 2 Elements of \$array are the same";
}else{
echo "The last 2 Elements of \$array are not identical.";
}
I have an array which looks like the following
array:2 [▼
0 => array:1 [▼
"input1" => "Something"
]
1 => array:1 [▼
"input2" => ""
]
]
Now the first element will always have some data. It is the second element I am interested in. At the moment, I am trying this
if(!empty($clientGroup[0][1]) || !empty($clientGroup[1][1]))
var_dump("Some Data");
} else {
var_dump("Both Empty");
}
The else should only be triggered if both elements are empty e.g.
array:2 [▼
0 => array:1 [▼
"input1" => ""
]
1 => array:1 [▼
"input2" => ""
]
]
If one of them have any data, the if should be triggered (so for the first array I showed, the if should be triggered).
How would I go about doing this, empty does not seem to work.
Thanks
The 2nd level keys do not exist so you will always be told the values are empty. Change the line
if(!empty($clientGroup[0][1]) || !empty($clientGroup[1][1]))
to,
if(!empty($clientGroup[0]['input1']) || !empty($clientGroup[1]['input2']))
and you should get the results you're after.
It's not realy 2D array because you have associative array inside an other array.
you must use key name (input1, input2) to access the value.
I recommend to use
if($retourdata[0]["input1"] !== "" || $retourdata[1]["input2"] !== "")
