there is a reason the class is called Test. say it slowly. let it
sink in... ;-) basically write a test class and play with it, e.g:
<?php
class Test
{
public static function staticDoPF() { call_user_func( array(self,"privFunc") ); }
public function doPF() { call_user_func( array($this,"privFunc") ); }
private function privFunc() { echo "Yeah PrivFunc!\n"; }
public static function staticDoPSF() { call_user_func( array(self,"privStatFunc") ); }
public function doPSF() { call_user_func( array($this,"privStatFunc") ); }
private static function privStatFunc() { echo "Yeah privStatFunc!\n"; }
}
$t = new Test;
// good
echo "works:\n-----\n";
Test::doPF();
$t->doPF();
call_user_func( array("Test","doPF") );
call_user_func( array($t,"doPF") );
Test::staticDoPF();
$t->staticDoPF();
call_user_func( array($t,"staticDoPF") );
call_user_func( array("Test","staticDoPF") );
Test::doPSF();
$t->doPSF();
call_user_func( array("Test","doPSF") );
call_user_func( array($t,"doPSF") );
Test::staticDoPSF();
$t->staticDoPSF();
call_user_func( array("Test","staticDoPSF") );
call_user_func( array($t,"staticDoPSF") );
// bad
echo "\ndont works | fatal errors (read source):\n-----\n";
//Test::privFunc();
//$t->privFunc();
//call_user_func( array("Test","privFunc") );
//call_user_func( array($t,"privFunc") );
//Test::privStatFunc();
//$t->privStatFunc();
//call_user_func( array("Test","privStatFunc") );
//call_user_func( array($t,"privStatFunc") );
