php satu kali muat naik memperkenalkan kod kira-kira berbilang keseluruhan dokumen Demo

前几天看了一本关于PHP的书，让我感触很深，我先介绍一下PHP的发展史，然后在教大家一个PHP上传多个文件的一个小技巧。让我们先来简单的介绍一下PHP吧！PHP 最初是1994年Rasmus Lerdorf创建的，刚刚开始只是一个简单的用Perl语言编写的程序，用来统计他自己网站的访问者。后来又用C语言重新编写，包括可以访问数据库。

以后越来越多的网站使用了PHP，并且强烈要求增加一些特性，比如循环语句和数组变量等等，在新的成员加入开发行列之后，在1995年中，PHP2.0发布了。第二版定名为PHP/FI(Form Interpreter)。PHP/FI加入了对mSQL的支持，从此建立了PHP在动态网页开发上的地位。到了1996年底，有15000个网站使用 PHP/FI；时间到了1997年中，使用PHP/FI的网站数字超过五万个。而在1997年中，开始了第三版的开发计划，开发小组加入了 Zeev Suraski 及 Andi Gutmans，而第三版就定名为PHP3。2000年，PHP4.0又问世了，其中增加了许多新的特性。以下给大家介绍一个PHP上传多个文件的方法。

PHP上传多个文件代码实现：

<ol class="dp-xml">
