Is it possible to delete an object's property in PHP?


php object 

unset($a->new_property);

This works for array elements, variables, and object attributes.

Example:

$a = new stdClass();$a->new_property = 'foo';var_export($a);  // -> stdClass::__set_state(array('new_property' => 'foo'))unset($a->new_property);var_export($a);  // -> stdClass::__set_state(array())

php object

This also works specially if you are looping over an object.

unset($object[$key])

Update

Newer versions of PHP throw fatal error Fatal error: Cannot use object of type Object as array as mentioned by @CXJ . In that case you can use brackets instead

unset($object->{$key})

php object

This also works if you are looping over an object.

unset($object->$key);

No need to use brackets.
