Objects
Object Initialization
To create a new object, use the new statement to instantiate a class:
<?php
class?foo
{
????function?do_foo()
????{
????????echo?"Doing?foo.";?
????}
}
$bar?=?new?foo;
$bar->do_foo();
?>For a full discussion, see the Classes and Objects chapter.
Converting to object
If an object is converted to an object, it is not modified. If a value of any other type is converted to an object, a new instance of the stdClass built-in class is created. If the value was NULL, the new instance will be empty. An array converts to an object with properties named by keys and corresponding values, with the exception of numeric keys which will be inaccessible unless iterated.
<?php
$obj?=?(object)?array('1'?=>?'foo');
var_dump(isset($obj->{'1'}));?//?outputs?'bool(false)'
var_dump(key($obj));?//?outputs?'int(1)'
?>For any other value, a member variable named scalar will contain the value.
<?php
$obj?=?(object)?'ciao';
echo?$obj->scalar;??//?outputs?'ciao'
?>← Iterables
