Sending email to a single

user - I

 For example, to send a mail using the mail() function

<?php

$to=“john@bluemountain.com ”;

$from=“tom@bluemountain.com ”;

$subject=”An example”;

$body=”This is an example.”;

$send=mail($to, $subject, $body, $from);

if($send)

{

echo “Mail Sent to $to address!!!”;

}

Sending email to a single

user - II

else

{

echo “Mail could not be sent to $to

address!!!”;

}

?>

Here, the mail is sent to john@bluemountain.com from

tom@bluemountain.com

Sending email to multiple

users - I

using mail() function

<?php

$to=“john@bluemountain.com,sam@bluemountain.com

,j@bluemountain.com”;

$from=“samson@bluemountain.com”;

for($i=0;$i<count($to);$i++)

{

$to[$i]=trim($to[$i]);

$subject=“An example”;

$body= “This is an example.”;

$send=mail($to, $subject, $body, $from);

Sending email to multiple

users - II

if($send)

{

echo “Mail was sent to all the addresses!!!”;

}

}

?>

Here, the mail is sent to all the users mentioned in the

receiver’s list from samson@bluemountain.com

Using attachment with

email

 An attachment is any text or graphics file sends with the email

 Uses an additional parameter, header, with the mail() function

 Syntax for the mail function with additional parameter is:

mail(string to, string subject, string message [, string additional_headers[, string additional_parameters]])

Where,

 string to – Specifies the receiver’s mail addresses

 string subject – Specifies the subject for the email

 string message – Specifies the messages that will be written in the mail

 string additional_headers – Specifies the mail sender’s address

 string additional_parameters – Specifies the headers those are set for attaching a file with the email

Example for using

attachment with email - I

 For example, to send an email with an attachment

<?php

$file = “/var/www/html/job.txt”;

$fp = fopen($file,“r”);

$content=fread($fp,filesize($file));

fclose($fp);

$to=“john@bluemountain.com ”;

$from=“jenny@bluemountain.com ”;

$subject=“Urgent Opening”;

$body=“”;

$mime_boundary = uniqid(“”);

$header.= $from;

$header.= $to;

$header.= “MIME-VERSION: 1.0\r\n”;

$header.=”Content-type: multipart/mixed”;

Example for using

attachment with email - II

$header.= “boundary=\””.$mime_boundary.”\””;

$message.=”Urgent Requirement.”;

$message.=”\r\n\r\n”;

$message.=”—“.$mime_boundary.”\r\n”;

1\”\r\n”;

$message.=”—“.$mime_boundary.”\r\n”;

$message.=“Content-Disposition:attachment;\r\n”;

$message.=“name=\“filename.extn\”\r\n”;

$message.=”\r\n\r\n”;

$message.=$file;

$message.=”\r\n\r\n”;

$message.=”—“.$mime_boundary.”\r\n”;

$content=“<P>.$content</P>”;

$content=str_replace(chr(10i,“<P></P>”,$content);

$mail_send=mail($to, $subject, $body, $message, $header);

Example for using

attachment with email - III

if($mail_send)

{

echo “To : $to &nbsp From : $from <P>”;

echo “Subject : $subject<P>”;

echo “The attached file content :<P>”

echo $content;

}

else

{

echo “<BR><BR>Mail could not be sent!!!”;

}

?>

Example for using

attachment with email - IV

 In this example, a boundary is made to separate

the original mail from the attachments

 Boundary is made with the help of uniqid()

function This function is used for assigning a

unique identifier to the original mail

 The value of this function is assigned to the

mime_boundary variable

 The content-type header indicates the type of

message that is attached with the email

Executing the codes

 Execute the codes in the Mozilla Web browser

The output appears as:

 mail() function is the inbuilt function of PHP that is used for

sending mails

 The implode() function is used for joining all the addresses

present in the array with a comma operator

 A boundary is created in between the actual e-mail and the

attachment with the help of the uniqid() function

 The base64_encode() function is used for accepting the data in the form of a string and returns the data in the original form to the

user

 The chunk_split() function is used for separating the data into smaller portions
