Use ArrayUtils to create an array from a JSON string and extract typed data from an array.

An ArrayUtilsException will be thrown if the array does not contain the given key or the value has an incorrect datatype.

Usage

Create an array from a JSON string.

try {
    $array = ArrayUtils::decodeJson(json: $json);
} catch (ArrayUtils $e) {
    // Error handling.
}

Extract typed data from an array.

try {
    $arrayValue         = ArrayUtils::getArrayFromKey(array $array, string $key);
    $arrayOrNullValue   = ArrayUtils::getArrayOrNullFromKey(array $array, string $key);
    $integerValue       = ArrayUtils::getIntegerFromKey(array $array, string $key);
    $integerOrNullValue = ArrayUtils::getIntegerOrNullFromKey(array $array, string $key);
    $floatValue         = ArrayUtils::getFloatFromKey(array $array, string $key);
    $stringValue        = ArrayUtils::getStringFromKey(array $array, string $key);
    $stringOrNullValue  = ArrayUtils::getStringOrNullFromKey(array $array, string $key);
    $booleanValue       = ArrayUtils::getBooleanFromKey(array $array, string $key);
} catch (ArrayUtils $e) {
    // Error handling.
}

Use getStringAsIntegerFromKey() if the value is a string with an integer value, e.q. '123'.

try {
    $integerValue = ArrayUtils::getStringAsIntegerFromKey(array $array, string $key);
} catch (ArrayUtils $e) {
    // Error handling.
}

Use getMixedFromKey() if you just want to extract data from an array without check of the datatype.

try {
    $integerValue = ArrayUtils::getMixedFromKey(array $array, string $key);
} catch (ArrayUtils $e) {
    // Error handling.
}
