PHP常用正则(手机号、座机、邮箱、身份证及手机号截取)

//验证手机号
$match = '/^((13[0-9])|(15[^4,d])|(18[0,5-9]))[0-9]{8}$/';
//验证座机
$match = '/^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$/';
//验证身份证号15或18位
$match = '/(^d{15}$)|(^d{17}(d|X|x)$)/';
//Email验证
$match = '/^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*$/';
//将手机号中间转换为 * 号
$tel = 18600000000;
$pattern = '/(d{3})d{4}(d{3})/';
$replacement = "$1****$2";
echo preg_replace($pattern,$replacement,$tel);
