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

Question

If I have an stdObject say, $a.

Sure there\'s no problem to assign a new property, $a,

$a->new_property = $         


        

Answer 1

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})

Answer 2

This also works if you are looping over an object.

unset($object->$key);

No need to use brackets.

Answer 3

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())

Answer 4

This code is working fine for me in a loop

$remove = array(
    "market_value",
    "sector_id"
);

foreach($remove as $key){
    unset($obj_name->$key);
}
