为何STATIC位置不同,结果产生了不同
  function A( ){
STATIC $a=10;
$a+=10;
echo $a;
}
A( ); // 20
A( ); //20
?>
=====================================================================

  function A( ){
STATIC $a 
  $a=10;
$a+=10;
echo $a;

A( ); //20
A( ); //30
?>


------解决方案--------------------
应该是第一个输出20 ,30 第二个 20,20
