Re: How to call a function from $classname

Colin Ross wrote:

under PHP5 at least, you should only be able to use $Class::method for public methods with a class, correct?

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") ); ?>

i.e. class Test {

       private function doIt_pri() { echo "done it!\n"; }
       public function doIt_pub() { echo "done it!\n"; }
       function doIt_pub2() { echo "done it!\n"; }

} $t = Test::doIt_pri(); // should fail $t = Test::doIt_pub(); // should work $t = Test::doIt_pub2(); // should also work since public is the default (assumed)

Test

== OR, does that rule only pertain to when a method is private, only methods WITHIN the class can call it?

Test

Hi, What do I have to do to call a function from $classname? Like: $classname->test( );

<?php // does $classname contain a name of a class? e.g: class Test {

       function doIt() { echo "done it!\n"; }

} $className = "Test"; $t = new $className; $t->doIt(); // also look at the functions // call_user_func() and call_user_func_array(), // e.g: call_user_func( array($className,"doIt") ); ?>
