Отправка вложений из формы на почту PHP

Есть форма.

<form data-toggle="validator" class="sendform" method="POST" enctype="multipart/form-data">             
    <h1>Text</h1>
    <p>text</p>                
    <input type="tel" name="phone" required placeholder="Tелефон"><br>
    <input type="text"  name="email" placeholder="E-mail"><br>
    <textarea type="text" name="comment" placeholder="Комментарий"></textarea><br>               
    <input type="file" multiple id="userfile" class="multi" maxlength="3"  data-maxfile="150000" name="userfile[]" accept="pdf|jpg|jpeg|png|xls|xlsx|doc|docx|bmp|mp4" />       
    <button type="submit" class="button">text</button>
    <p>text</p>
    <input type="hidden" name="MAX_FILE_SIZE" value="150000">
    <input type="hidden" name="files" id="upfiles"> 
</form>
