   $to = "sonoojaiswal1987@gmail.com";//change receiver address
   $subject = "This is subject";
   $message = "This is simple text message.";
   $header = "From:sonoojaiswal@javatpoint.com \r\n";

   $result = mail ($to,$subject,$message,$header);

   if( $result == true ){
      echo "Message sent successfully...";

   $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 Mail: Send Mail with Attachment

To send message with attachment, you need to mention many header information which is used in the example given below.

<?php
  $to = "abc@example.com";
  $subject = "This is subject";
  $message = "This is a text message.";
  # Open a file
  $file = fopen("tmp/test.html", "r" );//change your file location
  if( $file == false )
  {
     echo "Error in opening file";
     exit();
  }
  # Read the file into a variable
  $size = filesize("tmp/test.html");
  $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...";
