How do I access a static variable when I do not know the name of the
class until runtime?
I have the following example PHP:
ket% cat test.php
<?php
class Test
{
public static
$STEPS = array(
'foo',
'bar');
}
$className = 'Test';
var_dump($className::$STEPS);
ket%
Unfortunately when I run it I get:
ket% php test.php
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM
in /home/jablko/trash/test.php on line 13
ket%
I can call a static function using call_user_func(array($className,
'functionName')), and I can access a class constant using
constant($className.'::CONSTANT_NAME'). How do I access a static
variable?
this is also a not great but usable, stricter and faster solution:
<?php
class TestClass {
public static $STEPS = array( 'foo' , 'bar' );
public function steps() {
return self::getSteps();
}
public static function getSteps() {
return self::$STEPS;
}
public static function setSteps( $steps ) {
self::$STEPS = $steps;
}
}
$testClass = new TestClass;
print_r( $testClass->steps() );
?>
really though why..?
