Q1: PHP 怎样替换数据库读取出来的数组？？？
$str='admin=管理员system=系统user=用户vip=会员you=你me=我'; //用于替换的字符串
parse_str($str,$arr);
$arr=array_flip($arr);
$con=mysqli_connect('localhost','root','root','test'); //用户名，密码，数据库名自己修改
$a=mysqli_query($con,'select * from a'); //表名也请自己修改,表是按照您的要求设计的
$html="table border='1' width='500'trtdID/tdtd align='center'list/td/tr";
while($rel=mysqli_fetch_assoc($a)){
$item=explode(',',$rel['list']);
$item=array_filter($item);
$html=$html."tr";
$html=$html."td{$rel['ID']}/td";
foreach($item as $k=$v){
$b=array_search($v,$arr);
$str=$v;
$c=str_replace($str,$b,$str);
if($c=='') $c='窗口';
$html=$html."tdinput type='checkbox' value='{$str}' /{$c}/td";
}
$html."/tr";

$html.="/table";
echo $html;
Q2: 在phpadmin中如何替换mysql数据库中整个数据库中某个内容？
Update
用途：更新表中原有数据
单独使用，使用where匹配字段
set后面，更新字段值，既可以一次一项，也可以一次多项
例如1，
Update table_name Set column_name = new_value Where column_name = some_value
例：
“Person”表中的原始数据:
LastName FirstName Address City
Nilsen Fred Kirkegt 56 Stavanger
Rasmussen Storgt 67
运行下面的SQL将Person表中LastName字段为”Rasmussen”的FirstName更新为”Nina”：
UPDATE Person SET FirstName = 'Nina' WHERE LastName = 'Rasmussen'
更新后”Person”表中的数据为：
LastName FirstName Address City
Nilsen Fred Kirkegt 56 Stavanger
Rasmussen Nina Storgt 67
同样的，用UPDATE语句也可以同时更新多个字段：
例如2，
UPDATE Person SET Address = 'Stien 12', City = 'Stavanger' WHERE LastName = 'Rasmussen'
更新后”Person”表中的数据为：
LastName FirstName Address City
Nilsen Fred Kirkegt 56 Stavanger
Rasmussen Nina Stien 12 Stavanger
Q3: 怎么将已有的页面中的某一块内容调PHP数据库用表格的形式替换到已有页面上要替换的块内容 5 在线等
楼上说的对，用ajax的get或者post到php的制定方法，将从数据库查出来的返回值（一般用json）用js显示在页面上

Q5: 关于php网站更换数据库的问题，把mysql换成oracle数据库要怎么做？
更换数据库类型，那修改数据库相关的操作代码，可不是php将列表替换成数据库你想的这么简单哦
这可是个相当大的工程，几乎大部分文件都要修改！
所以建议php将列表替换成数据库你还是打消这个念头
