private $SizeOfGFG = 3;
}
// Using ReflectionProperty
$A = new ReflectionProperty('Company', 'SizeOfGeeksforGeeks');
$B = new ReflectionProperty('Company', 'SizeOfGFG');
// Calling the __toString() function
$C = $A->__toString();
$D = $B->__toString();
// Getting the string form of the specified property.
var_dump($C);
var_dump($D);
?>
输出:
string(52) "Property [ <default> private $SizeOfGeeksforGeeks ] " string(42) "Property [ <default> private $SizeOfGFG ] "
程序2:
<?php
// Initializing some user-defined classes
class Department1
{
protected $SizeOfHR;
}
class Department2
{
public $SizeOfCoding = 6;
}
class Department3
{
static $SizeOfMarketing = 9;
}
// Using ReflectionProperty over above classes
$A = new ReflectionProperty('Department1', 'SizeOfHR');
$B = new ReflectionProperty('Department2', 'SizeOfCoding');
$C = new ReflectionProperty('Department3', 'SizeOfMarketing');
// Calling the __toString() function and
// getting the string form of the specified property.
var_dump($A->__toString());
var_dump($B->__toString());
var_dump($C->__toString());
?>
输出:
string(43) "Property [ <default> protected $SizeOfHR ] " string(44) "Property [ <default> public $SizeOfCoding ] " string(44) "Property [ public static $SizeOfMarketing ] "
