主要是获取到地址栏的一些信息,域名,端口参数等
复制代码 代码如下:
//获取域名或主机地址
echo $_SERVER['HTTP_HOST']."
";
//获取网页地址
echo $_SERVER['PHP_SELF']."
";
//获取网址参数
echo $_SERVER["QUERY_STRING"]."
";
//来源网页的详细地址
echo $_SERVER['HTTP_REFERER']."
";
?>
php 获得当前的脚本网址(只有路径)
复制代码 代码如下:
function GetCurUrl()
{
if(!empty($_SERVER["REQUEST_URI"]))
{
$scrtName = $_SERVER["REQUEST_URI"];
$nowurl = $scrtName;
}
else
{
$scrtName = $_SERVER["PHP_SELF"];
if(empty($_SERVER["QUERY_STRING"]))
{
$nowurl = $scrtName;
}
else
{
$nowurl = $scrtName."?".$_SERVER["QUERY_STRING"];
}
}
return $nowurl;
}
//实例调用方法
//echo GEtCurUrl();
php 获取url地址不包含路径(域名或ip地址)
复制代码 代码如下:
function getServerName()
{
$ServerName = strtolower($_SERVER['SERVER_NAME']?$_SERVER['SERVER_NAME']:$_SERVER['HTTP_HOST']);
if( strpos($ServerName,'http://') )
{
return str_replace('http://','',$ServerName);
}
return $ServerName;
}
//实例调用方法
echo getServerName();
php 获取url地址包含端口路径
复制代码 代码如下:
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];

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.
