雷哥 数组这样:$arr[0] = 'a',$arr[2]='b',$arr[1]='c';arData[2]的key是空h=1;但是 h|-8=-7,但是我取arData[-7]的u1type确是0;
{val = {value = {lval = 0, dval = 0, counted = 0x0, str = 0x0, arr = 0x0, obj = 0x0, res = 0x0, ref = 0x0, ast = 0x0,
zv = 0x0, ptr = 0x0, ce = 0x0, func = 0x0, ww = {w1 = 0, w2 = 0}}, u1 = {v = {type = 0 '\000', type_flags = 0 '\000',
const_flags = 0 '\000', reserved = 0 '\000'}, type_info = 0}, u2 = {next = 0, cache_slot = 0, lineno = 0, num_args = 0,
fe_pos = 0, fe_iter_idx = 0, access_flags = 0, property_guard = 0}}, h = 0, key = 0x0} 雷哥这是为啥呢?我哪里理解错了吗?
