how to use explode for an array of objects

I have an array like that:

array(5) {
["code"]=>
int(1)
["messageError"]=>
string(27) "La typologie est incorrecte"
["model"]=>
string(3) "lot"
["grp_regles"]=>
array(1) {
[0]=>
array(1) {
[0]=>
array(3) {
["champ"]=>
string(21) "lot_surface_habitable"
["comparaison"]=>
string(7) "between"
["valeurAttendue"]=>
array(2) {
[0]=>
int(16)
[1]=>
int(40)
}
}
}
}
["prerequis"]=>
array(2) {
[0]=>
array(3) {
["champ"]=>
string(6) "typ_id"
["comparaison"]=>
string(1) "="
["valeurAttendue"]=>
int(1)
}
[1]=>
array(3) {
["champ"]=>
string(22) "tranche.fus.fup.fup_id"
["comparaison"]=>
string(1) "="
["valeurAttendue"]=>
int(1)
}
}
}

I want to do a foreach in “prerequis”:

$modelRetrieve = $this->retrieveModel($model);
        $modelFind = $modelRetrieve::find($id);
        $arrayError=[];
        $query = '';
        $path = storage_path() . "/json/controle.json";
        $json = file_get_contents($path);
        foreach (json_decode($json,true) as $key => $value) {
            $test = true;
            var_dump($value);
            if($value['model'] === $model ){
            foreach ($value['prerequis'] as $key => $value2) {
                if( $test && $modelFind[$value2['champ']] == (int)$value2["valeurAttendue"] ) 
                {
                    $test = true;
                }
            }
            }
        }

I need in second foreach to use in $value2['champ'] where $value2['champ'] is “tranche.fus.fup_id. So I need to explode that to have ['tranche']['fus']['fup_id']. How to use explode with that ? thanks everyone 🙂

Answer

you can use laravel data_get helper:

data_get($value2, $value2['champ'])
