how to use explode for an array of objects - php

Question

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 1

you can use laravel data_get helper:
data_get($value2, $value2['champ'])

Answer 2

To nest the $segments of the string starting with the innermost item of the result, we have to array_reverse() the $segments so we can loop over it and wrap each iteration's result with another array level in the next iteration until we looped through the whole $segments array.
$exploded = array_reduce(array_reverse(explode('.', $value2['champ'])), function($res, $segment) {
return [ $segment => $res ];
}, []);
