自己写一个验证Validate类，希望对大家开发有帮助

相信大家也用过thinkphp model 中的验证，也蛮好用的，自己在用前端js 验证类时感觉很多不错，自己就照着它的模式写了一个验证类，希望同学们喜欢
类中已经写好调用实例

示例1：普通调用
* $u_validate = Validate::model();
* //需要验证的数据
$data = array("name2"=>"0","name4"=>"admin173.com");
* //验证规则
$rules = array(
array('name'=>"name2","func"=>"min","params"=>1,"options"=>array('erroron'=>false)),
array('name'=>"name4","func"=>"email","params"=>1)
);
* //执行验证
$rtn = $u_validate->check($data, $rules);
if ($rtn === false) {
echo $u_validate->getError();
}
*
* 示例2：二维数组调用
* $u_validate = Validate::model();
$data = array(
array("name2"=>"1","name4"=>"admin173.com"),
array("name2"=>"中文sdfdsf","name4"=>"admin173.com")
);

$rules = array(
array('name'=>"name2","func"=>"min","params"=>1,"options"=>array('erroron'=>false)),
array('name'=>"name4","func"=>"email","params"=>1)
);

$rtn = $u_validate->check($data, $rules);

* 示例3：自定义错误消息
* $data = array("name2"=>"0","name4"=>"admin173.com");
* $u_validate = Validate::model();
* $rules = array(
array('name'=>"name2","func"=>"min","params"=>1,'msg'=>'最小值',"options"=>array('erroron'=>false)),
array('name'=>"name4","func"=>"email","params"=>1)
);
*
* $rtn = $u_validate->check($data, $rules);
*
* 示例4：调用其他验证方法
* $u_validate = new Validate();
$data = array(
array("name2"=>"1","name4"=>"admin173.com"),
array("name2"=>"中文sdfdsf","name4"=>"admin173.com")
);

$rules = array(
array('name'=>"name2","func"=>array(array(new Core(),'check')),"params"=>array(2,3),"options"=>array('erroron'=>false)),
);

$rtn = $u_validate->check($data, $rules);
if ($rtn === false) {
echo $u_validate->getError();
}
*
* 示例4：添加验证方法
$u_validate = Validate::model();
$data = array(
array("name2"=>"2","name4"=>"admin173.com"),
);

$rules = array(
array('name'=>"name2","func"=>array('checkname'),"params"=>3),
);
//添加验证方法
$rtn = $u_validate->add('checkname', array($this,'check'),'用户名不唯一');

$rtn = $u_validate->check($data, $rules);
if ($rtn === false) {
echo $u_validate->getError();
}
*
* 示例5：自定义验证方法参数,默认的params 参数失效
* $u_validate = Validate::model();
$data = array("name2"=>"2","name4"=>"ranglen",'tel'=>'13511111111');

$rules = array(
array('name'=>"name2","func"=>array('min',1),"params"=>3),
array('name'=>"name4","func"=>array('ranglen',array(10,20)),"params"=>3),
array('name'=>"tel","func"=>array($this,'check',array(10,20)),"params"=>3),
);

$rtn = $u_validate->check($data, $rules);
if ($rtn === false) {
echo $u_validate->getError();
}
*
*
*
*
* 验证规则参数介绍
* $rules =>array(
* 'name'=>"name2",//验证key 名称，可以理解为数组key
* "func"=>"min",//验证函数 支持!，比如!min
* "params"=>1,//传入的验证参数，比如验证最小值min,传入最小值 7，可以传入任何值
* 'msg'=>'错误消息',//自定义消息,数组，字符串
* "options"=>array(//配置信息其他配置
* 'on'=>false //验证错误后是否继续验证，true 继续 false 终止
* 'op'=>'&&' //操作符 && 与逻辑 或|| 逻辑
* )
* ),
