电力公司企业网站(Zblog内核)1.8
下载
由于我高估了大家对zblog程序的熟知度，发现还有很多站长并不是太熟悉这款程序，甚至连后台的登陆入口都不清楚。所以我晚上抽了一点点时间把该ZBLOG企业网站源码进行的修正，补充了大家的一些问题。并且我写了比较详细的使用教程，能够帮助新手朋友修改变成自己的企业网站使用。 修订版本改进了几处问题： 第一，修正了单页面中的顶部BANNER FLASH幻灯图片的显示错误问题； 第二，修正了在产品中心标题显
学习PHP时，你可能会遇到PHP上传多张图片问题，这里将介绍PHP上传多张图片问题的解决方法，在这里拿出来和大家分享一下。单张的图片上传是不复杂的，这里涉及到PHP上传多张图片和对图片格式的校验，保证上传的一定是图片，防止上传其他文件到服务器。
基本实现算法是使用数组的形式，把所有的图片提交个一个数组，对数组的元素进行一个个的处理。PHP其实不过是Web服务器的一个模块功能，所以首先要保证Web服务器的安全。当然Web服务器要安全又必须是先保证系统安全，这样就扯远了，无穷无尽。PHP可以和各种Web服务器结合，这里也只讨论Apache。非常建议以chroot方式安装启动Apache，这样即使Apache和PHP及其脚本出现漏洞，受影响的也只有这个禁锢的系统，不会危害实际系统。以下为引用的内容：
