从刚开始练习的PHP基础语法练习，到PHP语言在WEB中的应用，再到实际的项目开发，如留言版，相册系统，中小型公司网站系统，以及期间做过的有关团队合作的小游戏，让我受益匪浅，学到了很多。 后果图:
PHP代码
复制代码 代码以下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>网站法式备份</title>
</head>
<body>
<form name="myform" method="post" action="">
<?php
error_reporting(E_ALL & ~E_NOTICE);
ini_set("memory_limit", "2048M");
echo "选摘要紧缩的文件或目次：<br>";
$fdir = opendir("./");
while($file=readdir($fdir))
{
if($file=="." $file=="..")
continue;
echo "<input name="dfile[]" type="checkbox" value="$file" ".($file==basename(__FILE__)?"":"checked")."> ";
if(is_file($file))
{
echo "<font face=\"wingdings\" size=\"5\">2</font> $file<br>";
}
else
{
echo "<font face=\"wingdings\" size=\"5\">0</font> $file<br>";
}
}
?>
<br>
包括以下文件类型:
<input name="file_type" type="text" id="file_type" value="" size="50">
<font color="red">
(文件类型用""离隔,默许空则包括恣意文件,例:假如需求打包php和jpg文件,则输出"phpjpg")
</font>
<br>
紧缩文件保留到目次:
<input name="todir" type="text" id="todir" value="__dwb2011__" size="15">
<font color="red">
(留空为本目次,必需有写入权限)
</font>
<br>
紧缩文件称号:
<input name="zipname" type="text" id="zipname" value="dwb2011.zip" size="15">
<font color="red">
(.zip)
</font>
<br>
<br>
<input name="myaction" type="hidden" id="myaction" value="dozip">
<input type="button" value="反选" >
<input type="submit" name="Submit" value=" 入手下手紧缩 ">
<script language="javascript">

php manual（PHP手册）肯定是要从网上下载一个的，它很权威，也很全面，我自己认为它是一本很好的参考书，但是不适合新手当教材使用。 |
