本文实例讲述了php可扩展的验证类。分享给大家供大家参考。具体分析如下：

这里介绍一个可扩展的php验证类，
类里面可以的各类验证可自行调整实现，现在为基本实现方式。
需要添加规则的话， 直接定义方法，方法名即为规则名称。具体参考使用方法。

require_once('./Validator.class.php');$data = array( 'nickname' => 'heno' , 'realname' => 'steven', 'age' => 25, 'mobile' => '1521060426');$validator = new Validator($data);$validator->setRule('nickname', 'required');$validator->setRule('realname', array('length' => array(1,6), 'required'));$validator->setRule('age', array('required', 'digit'));$validator->setRule('mobile', array('mobile'));$result = $validator->validate();var_dump($result);var_dump($validator->getResultInfo());

Validator.class.php文件如下：

<?php/** * Validator 数据验证类 * @package library * @category library * @author Steven * @version 1.0 *//** * Validator 数据验证类 * @package library * @category library * @author Steven * @version 1.0 */class Validator { /** * 待校验数据 * @var array */ private $_data; /** * 校验规则 * @var array */ private $_ruleList = null; /** * 校验结果 * @var bool */ private $_result = null; /** * 校验数据信息 * @var array */ private $_resultInfo = array(); /** * 构造函数 * @param array $data 待校验数据 */ public function __construct($data = null) { if ($data) { $this->_data = $data; } } /** * 设置校验规则 * @param string $var 带校验项key * @param mixed $rule 校验规则 * @return void */ public function setRule($var, $rule) { $this->_ruleList[$var] = $rule; } /** * 检验数据 * @param array $data * <code> * $data = array('nickname' => 'heno' , 'realname' => 'steven', 'age' => 25); * $validator = new Validator($data); * $validator->setRule('nickname', 'required'); * $validator->setRule('realname', array('lenght' => array(1,4), 'required')); * $validator->setRule('age', array('required', 'digit')); * $result = $validator->validate(); * var_dump($validator->getResultInfo()); * </code> * @return bool */ public function validate($data = null) { $result = true; if ($this->_ruleList === null || !count($this->_ruleList)) { return $result; } foreach ($this->_ruleList as $ruleKey => $ruleItem) { if (!is_array($ruleItem)) { $ruleItem = trim($ruleItem); if (method_exists($this, $ruleItem)) { $tmpResult = $this->$ruleItem($ruleKey); if (!$tmpResult) { $this->_resultInfo[$ruleKey][$ruleItem] = $tmpResult; $result = false; } } continue; } foreach ($ruleItem as $ruleItemKey => $rule) { if (!is_array($rule)) { $rule = trim($rule); if (method_exists($this, $rule)) { $tmpResult = $this->$rule($ruleKey); if (!$tmpResult) { $this->_resultInfo[$ruleKey][$rule] = $tmpResult; $result = false; } } } else { if (method_exists($this, $ruleItemKey)) { $tmpResult = $this->$ruleItemKey($ruleKey, $rule); if (!$tmpResult) { $this->_resultInfo[$ruleKey][$ruleItemKey] = $tmpResult; $result = false; } } } } } return $result; } /** * 获取校验结果数据 * @return [type] [description] */ public function getResultInfo() { return $this->_resultInfo; } /** * 校验必填参数 * @param string $varName 校验项 * @return bool */ public function required($varName) { $result = false; if (is_array($this->_data) && isset($this->_data[$varName])) { $result = true; } return $result; } /** * 校验参数长度 * * @param string $varName 校验项 * @param array $lengthData array($minLen, $maxLen) * @return bool */ public function length($varName, $lengthData) { $result = true; if ($this->required($varName)) { $varLen = mb_strlen($this->_data[$varName]); $minLen = $lengthData[0]; $maxLen = $lengthData[1]; if ($varLen < $minLen || $varLen > $maxLen) { $result = true; } } return $result; } /** * 校验邮件 * @param string $varName 校验项 * @return bool */ public function email($varName) { $result = true; if ($this->required($varName)) { $email = trim($this->_data[$varName]); if (preg_match('/^[-\w]+?@[-\w.]+?$/', $email)) { $result = false; } } return $result; } /** * 校验手机 * @param string $varName 校验项 * @return bool */ public function mobile($varName) { $result = true; if ($this->required($varName)) { $mobile = trim($this->_data[$varName]); if (!preg_match('/^1[3458]\d{10}$/', $mobile)) { $result = false; } } return $result; } /** * 校验参数为数字 * @param string $varName 校验项 * @return bool */ public function digit($varName) { $result = false; if ($this->required($varName) && is_numeric($this->_data[$varName])) { $result = true; } return $result; } /** * 校验参数为身份证 * @param string $varName 校验项 * @return bool */ public function ID($ID) { } /** * 校验参数为URL * @param string $varName 校验项 * @return bool */ public function url($url) { $result = true; if ($this->required($varName)) { $url = trim($this->_data[$varName]); if(!preg_match('/^(http[s]?::)?\w+?(\.\w+?)$/', $url)) { $result = false; } } return $result; }}?>
