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) {  $result = true;  /* 如果没有设置校验规则直接返回 true */  if ($this->_ruleList === null || !count($this->_ruleList)) {   return $result;  }  /* 已经设置规则,则对规则逐条进行校验 */  foreach ($this->_ruleList as $ruleKey => $ruleItem) {   /* 如果检验规则为单条规则 */   if (!is_array($ruleItem)) {    $ruleItem = trim($ruleItem);    if (method_exists($this, $ruleItem)) {     /* 校验数据,保存校验结果 */     $tmpResult = $this->$ruleItem($ruleKey);     if (!$tmpResult) {      $this->_resultInfo[$ruleKey][$ruleItem] = $tmpResult;      $result = false;     }    }    continue;   }   /* 校验规则为多条 */   foreach ($ruleItem as $ruleItemKey => $rule) {    if (!is_array($rule)) {     $rule = trim($rule);     if (method_exists($this, $rule)) {      /* 校验数据,设置结果集 */      $tmpResult = $this->$rule($ruleKey);      if (!$tmpResult) {       $this->_resultInfo[$ruleKey][$rule] = $tmpResult;       $result = false;      }     }    } else {     if (method_exists($this, $ruleItemKey)) {      /* 校验数据,设置结果集 */      $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) {  $result = true;  /* 如果该项没有设置,默认为校验通过 */  if ($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) {  $result = true;  /* 如果该项没有设置,默认为校验通过 */  if ($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) {  $result = true;  /* 如果该项没有设置,默认为校验通过 */  if ($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) {  $result = true;  /* 如果该项没有设置,默认为校验通过 */  if ($this->required($varName)) {   $url = trim($this->_data[$varName]);   if(!preg_match("/^(http[s]?::)?w+?(.w+?)$/", $url)) {    $result = false;   }  }  return $result; }}?>
