这是一款开源的php代码，ExcelReader是专业地excel表进行读写操作的哦，下面我们来看一款ExcelReader读取111cn.net.xls工作表实例吧。

这是一款php mysql数据库备份与还原备份的代码，你可以随便的对你网站的数据库进行备份，同时也可以还原哦，这程序生成的是.sql的数据库文件，你也可以用其它工具导入，方便，生成的都是sql数据库备份语句，所以兼容性好。
inport.php
| 代码如下 |
复制代码 |
|
<?php
/**
* 数据库备份程序
*
* @author：黄乐
* @version：1.0
* @lastupdate：2010-7-19
*
*/
include("config/config.php");
include("includes/dbbackup.class.php");
include("includes/msg.class.php");
$dbbackup = new dbbackup($dbhost, $dbuser, $dbpwd, $dbname);
$msg = new msg();
$bakfile = $dbbackup->get_backup(); //获取备份文件
if($_get['fn']){
if($dbbackup->import($_get['fn'])){ //导入数据
$str = "恭喜您<br>备份数据已经成功导入！"; //提示信息
$msg->show_msg($str,'import.php','export.php'); //提示导入成功
}
}
//删除备份文件
if($_post['sub']){
echo $dbbackup->del($_post['choice'])? $msg->show_msg("恭喜您<br>备份文件已删除成功!",'import.php','export.php') : $msg->show_msg("删除失败!",'import.php','import.php');
}

实现原理很简单就是根据用户提交的数据到mysql数据表中查询是否有相同的，有就输出没有就不操作了。这是一款简单的记录搜索代码。
首先我们来创建搜索数据表
create table if not exists `search` (
`id` int(4) not null auto_increment,
`keyword` varchar(500) not null,
primary key (`id`)
) engine=myisam default charset=utf8 auto_increment=1 ;
保存数据
| 代码如下 |
复制代码 |
insert into `acc`.`search` (
`id` ,
`keyword`
)
values (
null , '内容搜索'
), (
null , 'php站内搜索'
); |
*/
//数据连接
| 代码如下 |
复制代码 |
|
$conn = mysql教程_connect('localhost','ac','1');//这里的ac用户名，1是密码，修改成你自己的mysql便可
$res = mysql_db_query('abc',"select * from search where keyword='内容搜索' ") or die(mysql_error());
if(mysql_num_rows($res) == 1) {
while($row = mysql_fetch_assoc($res)) {
foreach($row as $key => $val) {
echo $row['keyword'],'<br >';
}
}
}

php搜索csv中的数据原理是打开csv文件，然后一行行搜索指定的内容是否包含在我们读取这代码中，如果是返回true。
//搜索csv中指定内容
| 代码如下 |
复制代码 |
|
$fh = @fopen("csv_file_name", "r");
if($fh) {
if(flock($fh, lock_ex)) {
while(!feof($fh)) {
$line = fgets($fh);
if(strstr($line, $target_email_address) !== false) {
$data = split(",", $line); // $data *is* an array
}
}
flock($fh, lock_un);
}
fclose($fh);
}
|
| 代码如下 |
复制代码 |
$cn = mysql_connect('localhost','root','root');
if( $cn )
{
die('数据库连接成功');
}
else
{
die('连接失败');
} |
