   php 常用验证类及正则

  正则表达式在遇到新的时候将会不断更新

  include "ValidateParameterConfig.php";

  class Validation

  private static function getRexp($rexp)

  {

  $_rexp = array (

  'letter_number'=>'/^[0-9A-Za-z]+$/',//只有字母数字包括大小写

  'account'=>'/^[0-9A-Za-z_]+$/',//只有字母数字下划线包括大小写

  'ids'=>'/^[0-9]+(\,[0-9]+)*$/',//验证多个id以','分割的类型 例如'1,2,3,4,5'

  'number'=>'/^[0-9]+$/',//只可以使数字

  'personal_card'=>'/^[0-9A-Za-z]+$/',//身份证

  'email'=>'/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/',//邮箱

  'date'=>'/^((((19|20)\d{2})-(0?(1|[3-9])|1[012])-(0?[1-9]|[12]\d|30))|(((19|20)\d{2})-(0?[13578]|1[02])-31)|(((19|20)\d{2})-0?2-(0?[1-9]|1\d|2[0-8]))|((((19|20)([13579][26]|[2468][048]|0[48]))|(2000))-0?2-29))$/'//日期,包含了闰年

  );

  return $_rexp[$rexp];

  } else {

  return $rexp_not_defind;

  }

  }

  if ($k !== null) {

  return $k;

  }

  foreach($_config as $k=>$c) {

  if (isset($data[$k]))

  {

  if(isset($c['rexp']))

  {

  if (self::vRexp( $data[$k], $c['rexp']) === false) {

  }

  }

  }

  }

  public static function vRexp($data, $rexp) {

  if (preg_match($_rexp, $data) == false) {

  return false;

  }

  return true;

  }

  public static function vMaxLength($data, $l) {

  }

  return true;

  }

  public static function vLetterNumber($data) {

  if (preg_match(self::getRexp('letter_number'), $data) == false) {

  return false;

  }

  return true;

  }

  }

  public static function vEmail($data) {

  class ValidateParameterConfig

  {

  public static function getConfig ($key)

  {

  //'allow_exist'=>true或allow_exist不存在表示该参数必传

  $_config = array(

  'test'=>array(

  'letter_number'=>array('rexp'=>'letter_number', 'allow_exist'=>true),

  'number'=>array('rexp'=>'number', 'min_length'=>1'allow_exist'=>false),

  'account'=>array('rexp'=>'account', 'max_length'=>20),

  )

  );

  if (isset($_config[$key])) {

  return $_config[$key];

  } else {

  return $config_not_defind;

  }

  }

  }

  使用例子:

  从应用端发过来的参数为

  $arr = array('letter_number'=>'abc123', 'account'=>'acb1234_');

  //参数验证

  $_msg = Validation::validate($arr, 'test');

  if ($_msg !== null) {

  return $_msg . ' is invalid parameter';

  }
