I think not, but why don't we ask this to PHP ?
<?php
class Foo{}
$foo = new Foo;
var_dump(
method_exists( $foo, '__set' )
);
?>
*<< __set()* is run when writing data to inaccessible members. >>
http://php.net/__set
So, I think that when you write data to an non-existent member php will
first try is the object has an __set method, if not it'll raise a Fatal
Error
example 1:
<?php
Class Test{
}
$t = new Test;
$t->a = 'b'; # <-- add public property
print_r( $t );
example 2:
<?php
Class Test{
private $a;
}
$t = new Test;
$t->a = 'b'; # <-- fatal error
example 3:
<?php
Class Test{
private $a;
function __set($name, $value)
{
echo $name, ' <- ', $value, PHP_EOL;
}
}
$t = new Test;
$t->a = 'b'; # <-- trigger __set
example 4:
<?php
Class Test{
public $a;
private $c;
function __set($name, $value)
{
echo $name, ' <- ', $value, PHP_EOL;
}
}
$t = new Test;
$t->a = '1'; # <-- set the public property (don't trigger __set)
$t->b = '2'; # <-- trigger __set (property does not exists)
$t->c = '3'; # <-- trigger __set (property is private)
print_r( $t );
