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 >';
}
}
}

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。

if(!$allow_url_override || !isset($file_to_include))

}

}
if(!$allow_url_override || !isset($debug))
{
$debug = 0; //1 for on 0 for off
}
if(!$allow_url_override || !isset($force_nobr))
{
$force_nobr = 1; //force the info in cells not to wrap unless stated explicitly (newline)

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');
} |
这是一款比较适合php初学者学的教程哦，我们利用一个简单的实例来对数据库添加、修改、删除哦，这样更系统的让各位知道php mysql数据库操作的要点。
require_once('common.php');
$action = $_get['action'];
?>
