php设置cookie过期时间的方法:使用setcookie函数,设置该函数的第3个参数为有限时间戳即可;例“setcookie("名称", "值", time()+3600*24)”,就是设置一天后过期。
php怎么设置cookie过期时间?
php设置cookie的过期时间很简单,我们只需要使用setcookie函数即可设置
setcookie函数介绍
setcookie(name,value,expire,path,domain,secure)
参数:
name 设置cookie 的名称,该参数的值必须设置。
value 设置cookie的值,该参数必须设置。
expire 可选。设置cookie的有效期,一般为时间戳。
path 可选。设置cookie的服务器路径。
domain 可选。设置cookie的域名。
secure 可选。规定是否通过安全的 HTTPS 连接来传输cookie。
可以看出,要设置cookie过期时间,只需要设置滴三个参数即可。
设置cookie过期时间
设置cookie在一天后过期失效
setcookie ("mycookie", "123", time()+3600*24);
time()表示当前时间的时间戳,time()+3600*24就表示未来24小时的时间戳。
同理,设置cookie在一年后过期失效
setcookie ("mycookie", "123", time()+3600*24*365);
清除cookie
将cookie过期时间设置为过去时间
setcookie ("name", "xiaoming", time() - 1);

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.
