PHP 结合 扫描枪问题(扫描枪:超市扫条形码的)
怎么才能在PHP页面中得到扫描枪扫的条形码啊?
先谢谢各位朋友
------解决方案--------------------
兄弟,你先看看扫描枪二次开发用的说明书吧?
首先对于硬件厂商而言,他们生产一种产品,都要配上设备驱动的,如何安装设备,如何调用,一般都会有源代码,你问题问得就不对,你不该问怎么用php获得扫描枪扫出来的条形码呢?
因为这个问题没有答案,获取条形码的代码除了厂商,谁也不知道,厂商知道,所以他把这部分代码封装成了dll或者别的什么格式,当他的驱动在你的系统,或者嵌入式系统安装以后,调用他指定的dll中指定的函数就可以获取条形码
你应该和厂商充分联系过以后,得到API以后,再问怎么在php中调用dll等等问题
------解决方案--------------------
这个我做过
只要将你要输入条形码的文本框得到焦点
就是把光标移动到那
然后扫描枪会自动往那个文本框中输入条形码的
之后会有一个回车动作
相当于你用键盘输入条形码,再按下回车一样的效果

我也用这个方法,根本不需要什么驱动,超级简单.
