How To Sending attachments with email In PHP
Sending attachments with email: In PHP
To send an email with mixed content requires to set Content-type header tomultipart/mixed. Then text and attachment sections can be specified within boundaries.
A boundary is started with two hyphens followed by a unique number which can not appear in the message part of the email. A PHP function md5() is used to create a 32 digit hexadecimal number to create unique number. A final boundary denoting the email's final section must also end with two hyphens.
Attached files should be encoded with the base64_encode() function for safer transmission and are best split into chunks with the chunk_split() function. This adds \r\n inside the file at regular intervals, normally every 76 characters.
Following is the example which will send a file /tmp/test.txt as an attachment. you can code your program to receive an uploaded file and send it.

}
# 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@somedomain.com\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; ";
