How to call an associative array key in multidimensional array? - php

Question

I have a multidimensional array as below. I wish to check if the key [type] is equal to "select". If so, I wish to display the value of key [value]. How do I actually output the value of key [value] which is "Section 100." In the code below, it only outputs the value "select".
array_walk_recursive( $product_extras, function ($value, $key ) {
if( $key === 'type' && $value == 'select' ) {
echo "[$value]"; //This outputs "select". But I actually need the value from key [value]
}
});
My array.
Array
(
[product_id] => 8928
[title] => Example of an Event
[groups] => Array
(
[8929] => Array
(
[8932] => Array
(
[type] => select
[label] => Section
[id] => pewc_group_8929_8932
[group_id] => 8929
[field_id] => 8932
[value] => Section 100
[flat_rate] => Array
(
)
)
)
)
)

Answer 1

If you`re able to pass these ids as parameters in that function you should be able to do something like:
$product_extras['groups'][$runtime_group_id][$runtime_field_id]
With this you should access
Array(
[type] => select
[label] => Section
[id] => pewc_group_8929_8932
[group_id] => 8929
[field_id] => 8932
[value] => Section 100
[flat_rate] => Array

using array_map() and recursive(call itself)
call myfunction and send each value inside the array
function yourOuterFunction(){
//your code....
//your array $product_extras .......
array_map("myfunction",$product_extras);
function myfunction($value) {
//search is array or not
if(is_array($value)) {
//search array key and value
if(array_key_exists("type",$value) && array_search("select",$value) == true){
echo "Condition true FOUND..";
print_r($value);
}
//if not found then call itself
else if(is_array($value)) {
array_map("myfunction",$value);
}
}
}//myfunction close
}
