php连接mysql我有文章已经写过了,这篇文章主要是介绍从mysql中查询出结果之后怎么输出的问题。
一:mysqli_fetch_row();
查询结果:array([0]=>小王)
查询:
while ($row = mysqli_fetch_assoc($result)) {
$memberlist = $row[0];
}//end while()
二:mysqli_fetch_assos();
查询结果:array([name]=>小王)
查询:
while ($row = mysqli_fetch_assoc($result)) {
$memberlist = $row['memberlist'];
}//end while()
三、mysqli_fetch_array();
查询结果:array([0]=>小王 [name]=>小王)
查询:
while ($row = mysqli_fetch_assoc($result)) {
$memberlist = $row['memberlist'];
$memberlist = $row[0];
}//end while()
四、fetch_array();
查询结果:array([0]=>小王 [name]=>小王)
查询:` sql=“select?fromuser”; result = conn?>query( sql);
if (result)
{
if (result->num_rows>0)
{
while ( rows= result->fetch_array()) {
print_r( rows);echo“rows[‘id′]:”. rows[‘id’];
echo “
rows[‘name’]:”. rows[‘name′];echo“rows[‘pwd′]:”. rows[‘pwd’];
}//end while()
}else{
echo “
查询结果为空!”;
}//end if()
}else{
echo “
查询失败!”;
}//end if() `
从上面可以看出不同的函数输出的格式也是不一样的,mysqli_fetch_row()返回的是以数字做索引的,mysqli_fetch_assos()是以关键字做索引的,而mysqli_fetch_array()和fetch_array()即使用数字也使用关键字做索引。

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.
