PHP 匹配电话，手机，400号码 函数 及正则。很管用。

<?php function isTel($tel,$type='')
{
  $regxArr = array(
  'sj'  =>  '/^(\+?86-?)?(18|15|13)[0-9]{9}$/',
  'tel' =>  '/^(010|02\d{1}|0[3-9]\d{2})-\d{7,9}(-\d+)?$/',
  '400' =>  '/^400(-\d{3,4}){2}$/',
  );
  if($type && isset($regxArr[$type]))
  {
    return preg_match($regxArr[$type], $tel) ? true:false;
  }
  foreach($regxArr as $regx)
  {
    if(preg_match($regx, $tel ))
    {
      return true;
    }
  }
  return false;
}

$tm1 = microtime(true);
$arr = array(
'15910241024',
'+861591900 0000',
'86159 1930 9100',
