MySql database query results use table output PHP code example, mysql query results
In general websites, we will usually see that the data of many database tables are displayed in the browser They all appear in the table, which makes me feel amazing at first, but if you think about it carefully, it is not too complicated. Since you can return dql and dml in general, it should not be a problem to return it in the form of a table. However, there is one point to explain. What is wrong is that it is wrong to design a script on the client to implement the problem. Even if it can be implemented, it is very complicated. Therefore, we can only consider it on the server side. Think about the way to solve the problem, that is, print when returning Table labels and corresponding attributes and attribute values. Although this method seems unreasonable, it is also the most effective method. The specific code is as follows:
<?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.

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.
