Easy to use and reliable mail function php

How to send email with PHP. Although PHP has built in function mail() to send email, it's quite insecure and use nonobvious arguments. In below example function Send_mail can send mail when called with just four arguments: from, to, subject, text. To avoid email injection (using malformed parameters to send spam through mail()) removing of special characters is used.


<?php

*/

$site_admin = 'admin@example.com';

function Send_mail($from, $to, $subject, $text, $headers="")
{
    if (strtolower(substr(PHP_OS, 0, 3)) === 'win')
        $mail_sep = "\r\n";
    else
        $mail_sep = "\n";

    function _rsc($s)
    {
        $s = str_replace("\n", '', $s);
        $s = str_replace("\r", '', $s);
        return $s;
    }

    $h = '';
    if (is_array($headers))
    {
        foreach($headers as $k=>$v)
            $h = _rsc($k).': '._rsc($v).$mail_sep;
        if ($h != '') {
            $h = substr($h, 0, strlen($h) - strlen($mail_sep));
            $h = $mail_sep.$h;
        }
    }

    $from = _rsc($from);
    $to = _rsc($to);
    $subject = _rsc($subject);
    mail($to, $subject, $text, 'From: '.$from.$h);
}





if (($_SERVER['REQUEST_METHOD'] == 'POST') &&
    isset($_POST['subject']) && isset($_POST['text']) &&
    isset($_POST['from1']) && isset($_POST['from2']))
    {
        $from = $_POST['from1'].' <'.$_POST['from2'].'>';
        

        Send_mail($from, $site_admin, $_POST['subject'], $_POST['text'],
        array('X-Mailer'=>'4evertutorials.blogspot.in  Online PHP Examples with Source Code'));
        $mail_send = true;
    }



<html><head>Send us mail - 4evertutorials.blogspot.in
</head><body>
<?php
if (isset($mail_send)) {
    echo '

';
}
else {
