array_filter() will work. Try -
array_filter($array, function ($a) {
return count($a[0]) == 3; // return array with 3 elements only
});

PHP array slice multidimensional array

I have an multidimensional array but need to make it smaller.
This is an easy question I believe. I need to remove 1 array in
jsonresult array, the first one but preserve the other in the next array. I have tried array_splice but it only keeps one.
Array
(
[searchword] => search word
[jsonresult] => Array
(
[0] => Array // THIS ONE, KEEP ITS CHILDREN MOVE UP
(
[0] => Array
(
[id] => 14889770
)
[1] => Array
(
[id] => 14389720
)
[2] => Array
(
[id] => 14869723
)
)
[1] => Array // THIS ONE, KEEP ITS CHILDREN MOVE UP
(
[0] => Array
(
[id] => 14889722
)
[1] => Array
(
[id] => 14389711
)
[2] => Array
(
[id] => 14869329
)
)
)
)
Would like to get:
Array
(
[searchword] => search word
[jsonresult] => Array
(
[0] => Array
(
[id] => 14889770
)
[1] => Array
(
[id] => 14389720
)
[2] => Array
(
[id] => 14869723
)
[3] => Array
(
[id] => 14889722
)
[4] => Array
(
[id] => 14389711
)
[5] => Array
(
[id] => 14869329
)
)
)

Try this code. This may not be the correct method but it gives what you need. (As I understand from your question)
//creating a sample array similar to one you given in question.
$arr_test['searchword'] = 'search word';
$arr_test['jsonresult'] = array(array(array('id'=>14889770),array('id'=>14889720)),array(array('id'=>14889780),array('id'=>14889790)));
//creating new array
$arr_new = array();
//formatting array as you needed it
foreach($arr_test['jsonresult'] as $arr_jsonresult){
foreach($arr_jsonresult as $jsonresult){
$arr_new['jsonresult'][] = $jsonresult;
}
}
//overwriting the specific array key
$arr_test['jsonresult'] = $arr_new['jsonresult'];
//checking output
echo '<pre>';
print_r($arr_test);
This code produces the following output
Array
(
[searchword] => search word
[jsonresult] => Array
(
[0] => Array
(
[id] => 14889770
)
[1] => Array
(
[id] => 14889720
)
[2] => Array
(
[id] => 14889780
)
[3] => Array
(
[id] => 14889790
)
)
)

PHP search key in array and return its value?

I would like to search key in multidimensional array and i would like to get corrosponding value associated with that key.
For e.g.
I would like to extract following texts from below array :
SENT AT 12.08ms
And the text
sample id 41962
following is an array print_r() output :
Array
(
[0] => Array
(
[VERSION] => Array
(
[0] => Array
(
[group] =>
[param] => Array
(
)
[value] => Array
(
[0] => Array
(
[0] => 3.0
)
)
)
)
[SAMPLE] => Array
(
[0] => Array
(
[group] =>
[param] => Array
(
)
[value] => Array
(
[0] => Array
(
[0] => sample id 41962
)
)
)
)
[TSAM] => Array
(
[0] => Array
(
[group] =>
[param] => Array
(
)
[value] => Array
(
[0] => Array
(
[0] => sample group 141
)
[1] => Array
(
[0] => ¯
)
[2] => Array
(
[0] => sample batch 81
)
[3] => Array

)
)
)
)
[STATUS] => Array
(
[0] => Array
(
[group] =>
[param] => Array
(
[TYPE] => Array
(
[0] => CART
)
)
[value] => Array
(
[0] => Array
(
[0] => SENT AT 12.08ms
)
)
)
)
)
)
Can somebody provide me optimized code for above problem. The multidimensional array contains more than 5000 to 10000 arrays.

Please, see if my function works for you:
function get_value_by_key($array,$key)
{
foreach($array as $k=>$each)
{
if($k==$key)
{
return $each;
}
if(is_array($each))
{
if($return = get_value_by_key($each,$key))
{
return $return;
}
}
}
}
Use:
$array = array('array1'=>array('array2'=>array('find_some_key'=>'some_value')));
echo get_value_by_key($array,'find_some_key'); // outputs: some_value

If all the array keys have the same structure the following code should work:
foreach($array as $item){
$sentat = $item['STATUS'][0]['value'][0][0];
$sample = $item['SAMPLE'][0]['value'][0][0];
}
More detailed information would help us to provide you more tips :)

Conditionally replace values in multidimensional PHP array

There has been a few other questions regarding replacing values in multidimensional array on here, but I didn't find anything regarding what I was trying to do, exactly, per se.
I have an array that I get from an API and I need to update a few values based on other values in the array tree before sending the API payload to the browser.
In the array when the sale[0] === true I am looking for some logic to then replace the [price][0] value with a corresponding new sale price.
Using the foreach, I can easily loop through the each of the nodes in the array, but I am unsure once I loop through the array, how I can update the original array with new price if/when sale node === true.

Use a reference variable for the foreach iteration variable, then you can update the element in place.
foreach $data['response'][0]['results'][0]['items'] as &$item) {
if ($item['sale'][0]) {
$item['price'][0] = $new_price;
}
}
If you also need to loop through all the elements in the sale array, add a nested loop.
foreach $data['response'][0]['results'][0]['items'] as &$item) {
foreach ($item['sale'] as $i => $sale) {
if ($sale) {
$item['price'][$i] = $new_price;
}
}
}
