由一条别人adodb的bug引发的思考
echo 09, => (09)
;
echo 9, => (9)
;
你可以试一下.输出结果是:
0 => (09)
9 => (9)
而不是
09 => (09)
9 => (9)
这个译者做了下测试,经过分析得出.0开头的数字会被当成8进制,0x开头的会被当成16进制,如下:
echo 0x11, => (011)
;
echo 010, => (010)
;
这个会输出:
17 => (011)
8 => (010)
当然是10x16+1=17
1x8+0=8
ok.
someone reported a bug in adodb, the open source db library i maintain. i went crazy for half an hour until i realised the problem. here''s a little gotcha you can try:
echo 09, => (09)
;
echo 9, => (9)
;
if you expect the above code to produce the same values, you are sadly mistaken. try it. i will post a followup later :)
