I'm trying to remove stdClass property by reference. Because I don't know how deeply the property is nested, a reference is made in the loop. But the unset method does not remove variables by reference. How can I resolve it without just setting a null value?
<?php
$data = new stdClass();
$data->foo = new stdClass();
$data->foo->bar = 'value';
$pathToRemove = 'foo.bar';
$dataReference = &$data;
foreach (explode('.', $pathToRemove) as $field) {
$dataReference = &$dataReference->$field;
}
unset($dataReference);
var_dump($data);
Loop over all the elements except the last. Then use the last element as the field to delete.
$pathArray = explode('.', $pathToRemove);
$lastField = array_pop($pathArray);
$dataReference = &$data;
foreach ($pathArray as $field) {
$dataReference = &$dataReference->$field;
}
unset($dataReference->$lastField);
