PHP應(yīng)用
<?php
function foo() {
 echo "In foo()<br />\n";
}
function bar($arg = '') {
 echo "In bar(); argument was '$arg'.<br />\n";
}
// 使用 echo 的包裝函數(shù)
function echoit($string)
{
 echo $string;
}
$func = 'foo';
$func();  // This calls foo()
$func = 'bar';
$func('test'); // This calls bar()
$func = 'echoit';
$func('test'); // This calls echoit()
?>

PHP應(yīng)用
<?php
class Foo
{
 function Variable()
 {
  $name = 'Bar';
  $this->$name(); // This calls the Bar() method
 }
 function Bar()
 {
  echo "This is Bar";
 }
}
$foo = new Foo();
$funcname = "Variable";
$foo->$funcname(); // This calls $foo->Variable()
?>

PHP應(yīng)用
<?php
class Foo
{
 static $variable = 'static property';
 static function Variable()
 {
  echo 'Method Variable called';
 }
}
echo Foo::$variable; // This prints 'static property'. It does need a $variable in this scope.
$variable = "Variable";
Foo::$variable(); // This calls $foo->Variable() reading $variable in this scope.
?>
