    I hope this help you :

    First i just found email address in text and define that’s position

    Then i remove email from text and replace all dot (.) with double end of line

    And at last i again add email to text at the correct position

    <?php
$input = "Hello, Thanks for reaching us, we really appreciate your feedback! We are always trying to improve our product to provide you with a better experience.I will be sure to pass your suggestion onto our team for their consideration as we move forward with this. Call XYZ on 12345 or email at [email protected] if you have any question. Thank you for your email.";
$pattern = '/b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}b/';
preg_match_all($pattern, $input, $matches);
$email = $matches[0][0];
$emailpos = strpos($input, $email);
$output = '';
$input = str_replace($email,'',$input);
$sentences = preg_split('/(?<=[.!?])s+/', $input);
foreach ($sentences as $sentence) {
    $output .= rtrim($sentence, '.') . "nn";
}
$output = substr_replace($output, ' '.$email, $emailpos, 0);
echo $output;
?>

    • Split the text based on spaces.

    • Consider each continuous string of characters as tokens.

    • For each token, check if we have a period character . and if we have, check if it’s an email using filter_var. The regex approach to check if a string is an email is too complicated. See this.

    • If it’s not an email, replace the period character with a period character and new lines.

    • Implode the array back to a string based on a single space. Your text is now formatted with new lines.

    Snippet:

    <?php

$d = explode(" ", trim($str));

foreach($d as &$token){
    if(strpos($token, '.') !== false && !filter_var($token, FILTER_VALIDATE_EMAIL)) {
       $token = str_replace('.', ".nn", $token);
    }
}

echo implode(" ", $d);
