I need to delete a key in an array from a string.
String is translations.fr
Array is
[
...,
translations => [
fr => [
...
],
es => [
...
]
],
...,
]
Result must be :
[
...,
translations => [
es => [
...
]
],
...,
]
I think, using exlpode and unset is the good way.
Can you help me ? Thank's
Try this
unset(ArrayName[key][key].....)
Try this :
If you want to replace the same array and delete the "fr" completely
$translationArray = unset($translationArray['fr']);
If you want to retain the previous array and save the changes in a new one
$translationArrayNew = unset($translationArray['fr']);
I think this is what you're looking for:
$str = 'translations.fr';
$exploded = explode('.', $str);
$array = [
'translations' => [
'fr' => 'fr value',
'es' => 'es value',
]
];
unset($array[$exploded[0]][$exploded[1]]);
With explode you put your string into an array containing 2 keys:
0 => translations
1 => fr
This accesses the 'translations' key within your array
$array[$exploded[0]]
and this accesses the 'fr' key within 'translations'
$array[$exploded[0]][$exploded[1]]
it's like writing: $array['translations]['fr']
Solution :
public function deleteKeyV3($keyToDelete) {
$keys = explode('.', $keyToDelete);
$result = &$array;
foreach ($keys as $key) {
if (isset($result[$key])) {
if ($key == end($keys)) {
unset($result[$key]);
} else {
$result = &$result[$key];
}
}
}
}
unset($translation_arr['fr']);will work.
