Mail send with attachments in PHP step by step:

First, we create a simple HTML form with form attribute enctype="multipart/form-data"
Creating some HTML input box, textarea and for attachment input type="file"
Then we start with PHP code to send email with attachment.

Creating HTML Form

<form method="post" enctype="multipart/form-data">
	<input type="text" id="contact_name" class="form-control" placeholder="Name" name="user_name"/>
	<input type="text" id="contact_email" class="form-control" placeholder="Email Address"     
	name="user_mail">
	<textarea id="contact_message" class="form-control" rows="7" placeholder="Write a 
	message" name="user_message"></textarea>
	<input name="attachment" type="file">      
	<input type="submit" value="Send mail" class="btn btn-primary pull-right"/>
</form>

<input type="text" id="contact_email" class="form-control" placeholder="Email Address"

name="user_mail">

<textarea id="contact_message" class="form-control" rows="7" placeholder="Write a

message" name="user_message"></textarea>

</form>

On the above form enctype="multipart/form-data", this attribute is important for sending attachment.

PHP code to send email with attachment

First, we post all the data from the HTML Form using $_POST function.
Also, post the attachment using name attribute of that field.
For uploading file input type must have type="file"

 <?php
if(isset($_POST) && !empty($_POST)) {
 if(!empty($_FILES['attachment']['name'])) {
    $file_name = $_FILES['attachment']['name'];  
    $temp_name = $_FILES['attachment']['tmp_name'];  
    $file_type = $_FILES['attachment']['type'];

   $base = basename($file_name);

<?php

if(isset($_POST) && !empty($_POST)) {

if(!empty($_FILES['attachment']['name'])) {

$file_name = $_FILES['attachment']['name'];

$temp_name = $_FILES['attachment']['tmp_name'];

$file_type = $_FILES['attachment']['type'];

$base = basename($file_name);

Checking allowed an extension on below code,

$extension = substr($base, strlen($base)-4, strlen($base));

   //only these file types will be allowed
   $allowed_extensions = array(".doc", "docx", ".pdf", ".zip", ".png");

$extension = substr($base, strlen($base)-4, strlen($base));

//only these file types will be allowed

$allowed_extensions = array(".doc", "docx", ".pdf", ".zip", ".png");

If the file has satisfy allowed an extensions then go to next step,

//check that this file type is allowed
   if(in_array($extension,$allowed_extensions)) {
       //mail essentials
       $from = $_POST['user_mail'];
       $to = $_POST['user_mail'];
       $subject = $_POST['user_name'];
       $message = $_POST['user_message'];

       //things u need
       $file = $temp_name;
       $content = chunk_split(base64_encode(file_get_contents($file)));
       $uid = md5(uniqid(time()));  //unique identifier

       //standard mail headers
       $header = "From: ".$from."\r\n";
       $header .= "Reply-To: ".$replyto. "\r\n";
       $header .= "MIME-Version: 1.0\r\n";


       //declare multiple kinds of email (plain text + attch)
       $header .="Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n";
       $header .="This is a multi-part message in MIME format.\r\n";

       //plain txt part

       $header .= "--".$uid."\r\n";
       $header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
       $header .= "Content-Transfer-Encoding: 7bit\r\n";
       $header .= $message. "\r\n";


       //attch part
       $header .= "--".$uid."\r\n";
       $header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n";
       $header .= "Content-Transfer-Encoding: base64\r\n";
       $header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n";
       $header .= $content."\r\n";  //chucked up 64 encoded attch


       //sending the mail - message is not here, but in the header in a multi part

       if(mail($to, $subject, $message, $header)) {
       echo "success";
       
       }else {
           echo "fail";
           echo error_get_last()['message'];
       }


   }else {
       echo "file type not allowed"; }    //echo an html file
}else {
  echo "no file posted"; }    
}
?>

//check that this file type is allowed

if(in_array($extension,$allowed_extensions)) {

//mail essentials

$from = $_POST['user_mail'];

$to = $_POST['user_mail'];

$subject = $_POST['user_name'];

$message = $_POST['user_message'];

//things u need

$file = $temp_name;

$content = chunk_split(base64_encode(file_get_contents($file)));

$uid = md5(uniqid(time())); //unique identifier

//standard mail headers

$header = "From: ".$from."\r\n";

$header .= "Reply-To: ".$replyto. "\r\n";

$header .= "MIME-Version: 1.0\r\n";

//declare multiple kinds of email (plain text + attch)

$header .="Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n";

$header .="This is a multi-part message in MIME format.\r\n";

//plain txt part

$header .= "--".$uid."\r\n";

$header .= "Content-type:text/plain; charset=iso-8859-1\r\n";

$header .= "Content-Transfer-Encoding: 7bit\r\n";

$header .= $message. "\r\n";

//attch part

$header .= "--".$uid."\r\n";

$header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n";

$header .= "Content-Transfer-Encoding: base64\r\n";

$header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n";

$header .= $content."\r\n"; //chucked up 64 encoded attch

//sending the mail - message is not here, but in the header in a multi part

if(mail($to, $subject, $message, $header)) {

echo "success";

}else {

echo "fail";

echo error_get_last()['message'];

}

}else {

echo "file type not allowed"; } //echo an html file

}else {

echo "no file posted"; }

}

On the above PHP code, we create mail headers for sending PHP mail attachment.
