答一朋友问题:如何一次性删除多条记录。
一个简单示例
现有一个学生信息数据库,需要一次性删除多条记录
创建一个名为del.php的文件

代码如下:

Copy to Clipboard引用的内容:[www.bkjia.com]




$link=mysql_connect("localhost","root","");
mysql_select_db("zs");
$exec="select * from student";
$result=mysql_query($exec);
while($rs=mysql_fetch_object($result))
{
$id=$rs->sID;
$name=$rs->sName;
$sex=$rs->sSex;
$phone=$rs->sPhone;
?>




}
mysql_close();
?>
学生信息表
选项 学号 姓名 性别 电话
>


这个文件主要用来陈列数据库中的数据,并显示出来。

再建立一个名为sc.php的文件,其中代码如下:

Copy to Clipboard引用的内容:[www.bkjia.com] $link=mysql_connect("localhost","root","");
mysql_select_db("zs");
$id=$_POST['de'];
foreach($id as $ide){
$exec="delete from student where sID=$ide";
$result=mysql_query($exec);
if((mysql_affected_rows()==0) or (mysql_affected_rows==-1))
{
echo "没有找到记录,或者删除时出错";
exit;
}
else{
echo "学生信息已经删除";
}
}
mysql_close();
?>

用foreach的方式,分别将记录删除。

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
