title: Convert charcters from any languages to english characters
body: <p>I'm searching for a function that can transform or convert any characters (from all languages) to English characters.</p>
  
  <p>I saw <code>mb_convert_encoding</code>, <code>iconv('UTF-8', 'ASCII//TRANSLIT', $str)</code> , ....</p>
  
  <p>I probably miss something...</p>
  
  <p>Example : I want to go from '后杨庄' to 'hou yang zhuang'
  but iconv echo nothing ;( and mb_convert echo 后杨庄.</p>
  
  <p>Is someone knows how to better use mb_convert or iconv  ?
  or is there a better PHP function that can achieve this ?</p>
  
  <p>Thanks to answer</p>
