I have a multidimensional array and I want to create new variables for each array after apllying a function. I dont really know how to use the foreach with this kind of array. Here's my code so far:
$main_array = array
(
[first_array] => array
(
['first_array1'] => product1
['first_arrayN'] => productN
)
[nth_array] => Array
(
[nth_array1] => date1
[nth_arrayN] => dateN
)
)
function getresult($something){
## some code
};
foreach ($main_array as ["{$X_array}"]["{$key}"] => $value) {
$result["{$X_array}"]["{$key}"] = getresult($value);
echo $result["{$X_array}"]["{$key}"];
};
Any help would be appreciated!

foreach ($main_array as &$inner_array) {
foreach ($inner_array as &$value) {
$value = getresult($value);
echo $value;
}
}
unset($inner_array, $value);
Note the &
, which makes the variable a reference and makes modifications reflect in the original array.
Note: The unset
is recommended, since the references to the last values will stay around after the loops and may cause unexpected behavior if you're reusing the variables.

foreach($main_array AS $key=>$array){
foreach($array AS $newKey=>$val){
$array[$newKey] = getResult($val);
}
$main_array[$key] = $array;
}
