• Using `foreach` and `unset` function
$arr = array(<Data>);
$samples = array();
foreach ($arr as $key => $item) {
$obj = $this->fruitRepository->findByField('id', $item);
if (null == $obj) {
unset($arr[$key]);
} else {
$samples[] = $obj[0];
}
}
• Using `array_filter()` function.
$arr = array(<Data>);
$samples = array_filter(array_map(function($item) {
$obj = $this->fruitRepository->findByField('id', $item);
return $obj ? $obj[0] : null;
}, $arr));
• Using `array_diff` function
$arr = array(<Data>);
$invalid = array();
foreach ($arr as $key => $item) {
$obj = $this->fruitRepository->findByField('id', $item);
if (null == $obj) {
$invalid[] = $item;
}
}
$samples = array_diff($arr, $invalid);
