在一般的网站中,我们会通常看到,很多数据库中表的数据在浏览器都是出现在表格中的,一开始让自己感到很神奇,但是仔细想想也不算太复杂,既然可以dql和dml的一般返回,以表格的方式返回应该也不成问题,但是,有一点说明的是,在客户端设计脚本去实现问题是不对的,即便可以实现起来也是非常复杂,所以,只能在服务器的方面去考虑,想想问题解决的方式就有了,即在返回的时候打印表格标签和对应属性和属性值,虽然说这种方式看起来不太合理,但是这也是最为有效的方法。具体的代码如下:
<?php //在表格中显示表的数据,常用方式 function ShowTable($table_name){ $conn=mysql_connect("localhost","root","toor"); if(!$conn){ echo "连接失败"; } mysql_select_db("test",$conn); mysql_query("set names utf8"); $sql="select * from $table_name"; $res=mysql_query($sql,$conn); $rows=mysql_affected_rows($conn);//获取行数 $colums=mysql_num_fields($res);//获取列数 echo "test数据库的"."$table_name"."表的所有用户数据如下:<br/>"; echo "共计".$rows."行 ".$colums."列<br/>"; echo "<table style='border-color: #efefef;' border='1px' cellpadding='5px' cellspacing='0px'><tr>"; for($i=0; $i < $colums; $i++){ $field_name=mysql_field_name($res,$i); echo "<th>$field_name</th>"; } echo "</tr>"; while($row=mysql_fetch_row($res)){ echo "<tr>"; for($i=0; $i<$colums; $i++){ echo "<td>$row[$i]</td>"; } echo "</tr>"; } echo "</table>"; } ShowTable("test1"); ?>

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.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

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.

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),
