那些顯示對方ip信息的圖片是怎么制作的呢？今天就由我?guī)ьI(lǐng)著大家來制作一張吧，當(dāng)然這些可以很炫酷的簽名檔了，如果想特別定制的話可以私信我，本來是想在自己博客上提供一個網(wǎng)頁自動生成一些選項的，但是本著 * 一切輸入都是有害的* 的原則，沒有做，見諒了。o(￣▽￣)ゞ
之前逛貼吧，總是能夠看到很多很酷玄的簽名，就如下面這張雖然很簡陋，例如顯示出你現(xiàn)在的位置啊，瀏覽器啦什么的。之前一直不知道是怎么弄得，后來發(fā)現(xiàn)原來php是可以搞定的。
'try'
圖片的地址.
其實這個圖片制作也是很簡單的，下面是我的源碼，也可以參看Github
其中ip地址是可以采用PHP直接獲得的，然后地址查詢API是用的http://www.netimpact.com/ 提供的免費(fèi)服務(wù)，每天只可查詢250次，所以可能后面的就會出現(xiàn)不了結(jié)果的狀況。
