PHP mail()函数用于在PHP中发送电子邮件。 您可以使用PHP mail()函数来发送短信，HTML消息和附件与消息。
PHP mail()函数
语法
$to：指定邮件的接收者或接收者。 接收器必须指定以下格式之一。$subject: 代表邮件的主题。$message: 表示要发送的邮件的消息。$additional_headers(可选)：指定附加头，如From，CC，BCC等。额外的附加头也应该用CRLF(\r\n)分隔。
注意：消息的每一行应使用CRLF(
\r\n)分隔，并且行不应大于70个字符。
PHP邮件示例
文件：mailer.php
<?php
ini_set("sendmail_from", "maxsujaiswal@yiibai.com");
$to = "maxsujaiswal1987@gmail.com";//change receiver address
$subject = "This is subject";
$message = "This is simple text message.";
$header = "From:maxsujaiswal@yiibai.com \r\n";
$result = mail ($to,$subject,$message,$header);
if( $result == true ){
echo "Message sent successfully...";
}else{
echo "Sorry, unable to send mail...";
}
?>
如果在运行服务器上运行此代码，它将向指定的接收方发送电子邮件。
PHP邮件：发送HTML消息
要发送HTML消息，您需要在消息标题中提及Content-type text/html。
<?php
$to = "abc@example.com";//change receiver address
$subject = "This is subject";
$message = "<h1>This is HTML heading</h1>";
$header = "From:xyz@example.com \r\n";
$header .= "MIME-Version: 1.0 \r\n";
$header .= "Content-type: text/html;charset=UTF-8 \r\n";
$result = mail ($to,$subject,$message,$header);
if( $result == true ){
echo "Message sent successfully...";
}else{
echo "Sorry, unable to send mail...";
}
?>
PHP邮件：使用附件发送邮件
要使用附件发送消息，您需要提及许多标题信息，在下面给出的示例中使用。
<?php
$to = "abc@example.com";
$subject = "This is subject";
$message = "This is a text message.";
# Open a file
$file = fopen("/tmp/test.txt", "r" );//change your file location
if( $file == false )
{
echo "Error in opening file";
exit();
}
# Read the file into a variable
$size = filesize("/tmp/test.txt");
$content = fread( $file, $size);
# encode the data for safe transit
# and insert \r\n after every 76 chars.
$encoded_content = chunk_split( base64_encode($content));
# Get a random 32 bit number using time() as seed.
$num = md5( time() );
# Define the main headers.
$header = "From:xyz@example.com\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; ";
$header .= "boundary=$num\r\n";
$header .= "--$num\r\n";
# Define the message section
$header .= "Content-Type: text/plain\r\n";
$header .= "Content-Transfer-Encoding:8bit\r\n\n";
$header .= "$message\r\n";
$header .= "--$num\r\n";
# Define the attachment section
$header .= "Content-Type: multipart/mixed; ";
$header .= "name=\"test.txt\"\r\n";
$header .= "Content-Transfer-Encoding:base64\r\n";
$header .= "Content-Disposition:attachment; ";
$header .= "filename=\"test.txt\"\r\n\n";
$header .= "$encoded_content\r\n";
$header .= "--$num--";
# Send email now
$result = mail ( $to, $subject, "", $header );
if( $result == true ){
echo "Message sent successfully...";
}else{
echo "Sorry, unable to send mail...";
}
?>
