问题描述
[PHP]
函数blah（$ item）{
if（！isset（$ baseDir））{
static $ baseDir ='''';
$ baseDir = $ item;
print_r（" baseDir = $ baseDir \ n"）;
}
$ dirID = opendir（$ item）;
while（（$ fyl = readdir（$ dirID））！== false）{
if（is_dir（" $ baseDir / $ fyl"））blah（$ item）;
//如果它是一个文件，请做其他麻烦
}
}
[/ PHP]
我使用PHP 4.3.2并且以下内容发生在blah中（ ）：
[PHP]
function blah($item) {
if (!isset($baseDir)) {
static $baseDir = '''';
$baseDir = $item;
print_r("baseDir = $baseDir\n");
}
$dirID = opendir($item);
while (($fyl = readdir($dirID)) !== false) {
if (is_dir("$baseDir/$fyl")) blah($item);
// DO OTHER STUFF IF IT IS A FILE
}
}
[/PHP]
I am using PHP 4.3.2 and the following occurs within blah() :
我的印象是静态变量保留其值
整个函数（或方法）递归内存堆栈。然而，它每次都会改变
因为它显然会失去它的设定值。
不用说我很困惑。我对静态是错的;如果是的话，
我还能做些什么来保留这个价值？我不能使用$ _SESSION这个
是命令行PHP而不是API。
Thanx

I was under the impression that a static variable retains its value
throughout a function (or method) recursive memory stack. However, it
changes everytime because it apparently loses its set value.
Needless to mention I''m confused. Was I wrong about static; if so,
what else do I do to retain this value? I cannot use $_SESSION as this
is command-line PHP instead of API.
Thanx
