I have this array :

(

  [id] => block_5df755210d30a

  [name] => acf/floorplans

  [data] => Array

  (

    [floorplans_0_valid_for_export] => 0

    [floorplans_0_title] => title 1

    [floorplans_0_house_area] => 40m²

    [floorplans_0_bedrooms] => 1

    [floorplans_1_valid_for_export] => 1

    [floorplans_1_title] => title xx

    [floorplans_1_house_area] => 90m²

    [floorplans_1_bedrooms] => 2

    [floorplans_2_valid_for_export] => 1

    [floorplans_2_title] => title 2

    [floorplans_2_house_area] => 50m²

    [floorplans_2_bedrooms] => 1

    [floorplans] => 3



  )

)

As we can see in the data, we have fields (floorplans_X_valid_for_export).
What I want to do is to get the data only when this field equal to 1.

So from the given example, I want to keep only these fields:

[floorplans_1_valid_for_export] => 1

[floorplans_1_title] => title xx

[floorplans_1_house_area] => 90m²

[floorplans_1_bedrooms] => 2

[floorplans_2_valid_for_export] => 1

[floorplans_2_title] => title 2

[floorplans_2_house_area] => 50m²

[floorplans_2_bedrooms] => 1

I want to loop through this array and retain only the elements that relate to the key "city" with a value of "New York". Here's how you can achieve this in PHP:

php
$array = [
'id' => 1,
'name' => 'John',
'age' => 25,
'city' => 'New York',
'gender' => 'male'
];

$newArray = [];

foreach ($array as $key => $value) {
if ($key === 'city' && $value === 'New York') {
$newArray[$key] = $value;
}
}

print_r($newArray);


This code will output:


Array
(
[city] => New York
)


This way, you retain only the element with the key "city" and the value "New York" in a new array.
