本文实例讲述了PHP验证类的封装与使用方法。分享给大家供大家参考，具体如下：
<?php
/**
* Created by PhpStorm.
* User: jiqing
* Date: 18-7-24
* Time: 下午4:36
* 常用验证
*/
class Valid
{
static protected $error;
static protected $error_tips = [
'tel' => '手机号格式有误',
'email' => '邮箱格式有误',
'max_len' => '参数长度不能超过最大长度',
'min_len' => '参数长度不能小于最小长度',
'required' => '缺少参数'
];
// required|max_len,100|min_len,6
public function validate($field, $rules)
{
$rules = explode('|', $rules);
foreach ($rules as $rule) {
$method = null;
$param = null;
// Check if we have rule parameters
if (strstr($rule, ',') !== false) {
$rule = explode(',', $rule);
$method = 'check_'.$rule[0];
$param = $rule[1];
$rule = $rule[0];
} else {
$method = 'check_'.$rule;
}
$method_array = get_class_methods(new Valid());
if (!in_array($method,$method_array)) {
self::$error[] = "Method not exist.";
}
if (!self::$method($field,$param)) {
self::$error[] = self::$error_tips[$rule] ? self::$error_tips[$rule] : '参数格式有误';
}
}
if (count(self::$error) == 0) {
return 0;
}
return self::$error[0]; // 返回第一个错误
}
public static function check_required($field) {
if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) {
return true;
} else {
return false;
}
}
public static function check_tel($field) {
if(preg_match("/^1[345678]{1}\d{9}$/",$field)){
return true;
}else{
return false;
}
}
public static function check_email($field) {
if(preg_match("/^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/",$field)){
return true;
}else{
return false;
}
}
public static function check_max_len($field,$param = null) {
if (function_exists('mb_strlen')) {
if (mb_strlen($field) <= (int) $param) {
return true;
} else {
return false;
}
} else {
if (strlen($field) <= (int) $param) {
return true;
} else {
return false;
}
}
}
public static function check_min_len($field,$param = null) {
if (function_exists('mb_strlen')) {
if (mb_strlen($field) >= (int) $param) {
return true;
} else {
return false;
}
} else {
if (strlen($field) >= (int) $param) {
return true;
} else {
return false;
}
}
}
public static function check_regex($field, $param = null)
{
$regex = $param;
if (preg_match($regex, $field)) {
return true;
} else {
return false;
}
}
}
基本满足需求。
vendor('Func.Valid');
if ($res = Valid::validate('152','required|regex,/^1[345678]{1}\d{9}$/')) {
$this->json->setErr(10001,$res);
$this->json->Send();
}
封装很有意思，这个类唯一的亮点，就是可以复合验证。并且支持正则。而且里面的验证方法还可以单独使用。
vendor('Func.Valid');
if (!Valid::check_tel('152')) {
$this->json->setErr(10001,'手机号有误');
$this->json->Send();
}
勇敢的封装，利国利民。
继续封装，支持数组传参。

使用如下
vendor('Func.Valid');
$validators = [
'tel' => 'required|tel',
'name' => 'required',
'email' => 'r|email',
'password' => 'r|min_len,6|max_len,12'
];
if ($err = Valid::is_valid($validators,$_POST)) {
$this->json->setErr(10001,$err);
$this->json->Send();
}
继续优化！支持错误提示中，添加参数。
