?>
When I send email through windows than send properly but when I run script on linux than attachment mail send in plain text.
Email sent in full text shown in below:

Answer 1

It is because of situations like this (cross-platform compatibility) that the PHP constant PHP_EOL exists. Do this:
<?php
....
$eol = PHP_EOL;
$headers = "From: ticketing#soite.com".$eol."Reply-To: mukesh#solite.com";
$random_hash = md5(date('r', time()));
$headers .= $eol."Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
$attachment = chunk_split(base64_encode(file_get_contents($file1))); // Set your file path here
//define the body of the message.
$message = "--PHP-mixed-$random_hash".$eol."Content-Type: text/html; charset=\"iso-8859-1\"".$eol."Content-Transfer-Encoding: 7bit".$eol.$eol;
//Insert the html message.
$message .= $htmlbody.$eol.$eol."--PHP-mixed-$random_hash".$eol;
//include attachment
$message .= "Content-Type: application/pdf; name=\"$name\"".$eol."Content-Transfer-Encoding: base64".$eol."Content-Disposition: attachment; filename=\"".$name."\"".$eol;
$message .= $attachment;
$message .= $eol."--PHP-mixed-$random_hash--";
//send the email
$mail = mail( $to, $subject , $message, $headers );
echo $mail ? "Mail sent" : "Mail failed";
?>
EDIT:
Based on new information in your comment, and another look at the code, I wonder why windows ever delivered the message as html. You specified the content-type as text/plain here
$message = "--PHP-alt-$random_hash\r\n"."Content-Type: text/plain; charset=\"iso-8859-1\"\r\nContent-Transfer-Encoding: 7bit\r\n\r\n"
You should change that to simply
$message = "--PHP-alt-$random_hash".$eol."Content-type:text/html; charset=iso-8859-1".$eol."Content-Transfer-Encoding: 7bit".$eol.$eol;
This should most likely resolve your problem.

Check changes I made to the main answer...

Answer 2

Use Linux style newline characters: \n instead of \r\n, or, use PHP_EOL constant.

Answer 3

Use PHP_EOL constant. It substitutes end of line based on platform
specific.
Note: mysql_query was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used.Alternatives to this function include: mysqli_query() or PDO::query()
You basically have two options to achieve this:
1.Using PDO (for any supported database driver):
$stmt = $pdo->prepare('SELECT * FROM employees WHERE name = :name');
$stmt->execute(array('name' => $name));
foreach ($stmt as $row) {
// do something with $row
}
2.Using MySQLi (for MySQL):
$stmt = $dbConnection->prepare('SELECT * FROM employees WHERE name = ?');
$stmt->bind_param('s', $name);
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
// do something with $row
}
