用php mysql一个名片库程序,有分类查找,分页功能。
第一步:按下列代表先做个静态页面。
第二步:如下建库。
id int(4) 否 auto_increment
http varchar(25) 否
name varchar(50) 否
email varchar(50) 否
gs varchar(200) 否
address varchar(200) 否
yb varchar(20) 否
zw varchar(100) 否
tel varchar(20) 否
fax varchar(20) 否
bp varchar(20) 否
第三步:查找执行程序
if (!isset($show)) $show=0;
{
if($query1=="查找")
{
$db=mysql_connect("localhost","用户名","密码");
$dbname=mysql_select_db("库文件名",$db);
mysql_query('select * from 表文件名',$db);
$limit=2; //一页显示几条内容。
//global $query,$queryyy,$quer;
switch($inout)
{
case "N":
//按姓名查找
$query="select * from card where name like '%$keyword%'";
$queryyy = "select * from card where name like '%$keyword%' order by id desc limit $show, $limit";
break;
case "C":
//按地区查找
$query="select * from card where address like '%$keyword%' order by id desc";
$queryyy = "select * from card where address like '%$keyword%' order by id desc limit $show, $limit";
break;
case "A":
// 按职务查找
$query="select * from card where zw like '%$keyword%' order by id desc";
$queryyy = "select * from card where zw like '%$keyword%' order by id desc limit $show, $limit";
break;
}
$result1=mysql_query($query);
$total=mysql_num_rows($result1); //总的符合条件的记录数
$quer=mysql_query($queryyy,$db);
$pages=ceil($total/$limit);
}
}
?>
你查找的关键字是:: echo $keyword;?>
echo "
查找名片如下: 共有["; echo $total; echo "]张名片 | 共分["; echo $pages; echo "]页 |
while ($row = mysql_fetch_array($quer))
{
echo "
|
";
}
$vor = $show $limit;
$back = $show - $limit;
print "
print "
"; for ($i=1;$i { $new_offset=$limit*($i-1); $parameter="query1=$query1&keyword=$keyword&inout=$inout"; print " $i$nbsp"; } print " |
"; //显示上一页 if ($show - $limit >= 0) { print " 上一页"; } print " |
"; //显示下一页 if (($show $limit) { print "下一页 "; } print " |
"; //显示全部留言 //print "全部名片 "; print " |
print "
?>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
