  // 检测字符串是否为空
  $oldStr=trim($oldStr);
  $numbers = array();
  if(empty($oldStr)){
    return $numbers;
  }
  // 删除86-180640741122，0997-8611222之类的号码中间的减号（-）
  $strArr = explode("-", $oldStr);
  $newStr = $strArr[0];
  for ($i=1; $i < count($strArr); $i++) { 
    if (preg_match("/\d{2}$/", $newStr) && preg_match("/^\d{11}/", $strArr[$i])){
      $newStr .= $strArr[$i]; 
    } elseif (preg_match("/\d{3,4}$/", $newStr) && preg_match("/^\d{7,8}/", $strArr[$i])) {
      $newStr .= $strArr[$i]; 
    } else {
      $newStr .= "-".$strArr[$i]; 
    } 
  }
  // 手机号的获取
