Regarding [Jakob Thomsen 26-Feb-2008 12:57]; below is are two modifications to your code: (1)
"As of PHP 5.3.0, it's possible to reference the class using a variable."( http://www.php.net/manual/en/language.oop5.paamayim-nekudotayim.php
) ; however, you still cannot reference a static function using a variable; and (2) there does seem
to be a workaround using eval (that I can't explain, perhaps another can enlighten us):
<?php
class foo {
public static function bar(){
return "bar in a class called";
}
}
function bar() {
return "normal bar called";
}
$strFN = "bar";
echo $strFN(); // => "normal bar called"
$strCL = "foo";
echo $strCL::bar(); // (1) As of 5.3.0 => "bar in a class called"
$strFN2 = "foo::bar";
eval('$x = ' . 'foo::' . '$strFN();'); // (2) eval works for variable
static function name
echo $x; // => "bar in a class called"
echo $strFN2(); // Fatal error: Call to undefined function foo::bar()
?>
