<?php require_once 'Zend/Validate/Date.php'; function c_date($date){ $validator = new Zend_Validate_Date(); if($validator->isValid($date)){ echo "输入的日期格式："; echo $date."有效！<p>"; }else{ echo "输入的日期格式："; echo $date."无效！<p>"; } } $date1 = "2008-02-15"; $date2 = "2008-02-31"; $date3 = "02-15-2008"; c_date($date1); c_date($date2); c_date($date3);
结果：
输入的日期格式：2008-02-15有效！
输入的日期格式：2008-02-31无效！
输入的日期格式：02-15-2008无效！

public function isValid($value) { if (!is_string($value) && !is_int($value) && !is_float($value) && !is_array($value) && !($value instanceof Zend_Date)) { $this->_error(self::INVALID); return false; } $this->_setValue($value); if (($this->_format !== null) || ($this->_locale !== null) || is_array($value) || $value instanceof Zend_Date) { require_once 'Zend/Date.php'; if (!Zend_Date::isDate($value, $this->_format, $this->_locale)) { if ($this->_checkFormat($value) === false) { $this->_error(self::FALSEFORMAT); } else { $this->_error(self::INVALID_DATE); } return false; } } else { if (!preg_match('/^\d{4}-\d{2}-\d{2}$/', $value)) { $this->_format = 'yyyy-MM-dd'; $this->_error(self::FALSEFORMAT); $this->_format = null; return false; } list($year, $month, $day) = sscanf($value, '%d-%d-%d'); if (!checkdate($month, $day, $year)) { $this->_error(self::INVALID_DATE); return false; } } return true; }
InArray数组包含校验器
如果内容包含在数组中将返回True，否则返回False。
代码：
<?php require_once 'Zend/Validate/InArray.php'; function c_array($n){ $temp = array("北京","上海","天津","重庆"); $validator = new Zend_Validate_InArray($temp); if($validator->isValid($n)){ echo "指定的内容："; echo $n.",存在于指定数组中！<p>"; }else{ echo "指定的内容："; echo $n.",不存在于指定数组中！<p>"; } } $city1 = "北京"; $city2 = "重庆"; $city3 = "郑州"; c_array($city1); c_array($city2); c_array($city3);
结果：
指定的内容：北京,存在于指定数组中！
指定的内容：重庆,存在于指定数组中！
指定的内容：郑州,不存在于指定数组中！
Regex正则匹配校验器
通过使用正则表达式，再加上合理使用本校验器，几乎可以实现所有的校验规则。
代码：
<?php require_once "Zend/Validate.php"; function c_rege($v){ $pattern = array("/ab{2,}/"); if(Zend_Validate::is($v,"Regex",$pattern)){ echo "<font color=\"#006600\">指定的内容："; echo $v."<p>符合定义的正规规则！</font>"; echo "<p>"; }else{ echo "<font color=\"#ff0000\">指定的内容："; echo $v."<p>不符合定义的正规规则！</font>"; echo "<p>"; } } $temp1 = "ab"; $temp2 = "abb"; $temp3 = "abbb"; c_rege($temp1); c_rege($temp2); c_rege($temp3);
结果：
指定的内容：ab
不符合定义的正规规则！
指定的内容：abb
符合定义的正规规则！
指定的内容：abbb
符合定义的正规规则！
点评：
public function __construct($pattern) { if ($pattern instanceof Zend_Config) { $pattern = $pattern->toArray(); } if (is_array($pattern)) { if (array_key_exists('pattern', $pattern)) { $pattern = $pattern['pattern']; } else { require_once 'Zend/Validate/Exception.php'; throw new Zend_Validate_Exception("Missing option 'pattern'"); } } $this->setPattern($pattern); }
构造函数初始化私有属性，
public function isValid($value) { if (!is_string($value) && !is_int($value) && !is_float($value)) { $this->_error(self::INVALID); return false; } $this->_setValue($value); $status = @preg_match($this->_pattern, $value); if (false === $status) { $this->_error(self::ERROROUS); return false; } if (!$status) { $this->_error(self::NOT_MATCH); return false; } return true; }
进行验证工作。
自定义校验器编写
继承Zend_Validate_Interface接口实现用户自定义校验器。
代码案例，功能判断指定数值是否为3的倍数。
接口代码：

The array keys are validation failure message identifiers, * and the array values are the corresponding human-readable message strings. * * If isValid() was never called or if the most recent isValid() call * returned true, then this method returns an empty array. * * @return array */ public function getMessages(); }
要实现其中的两个方法，一个是isValid()，一个是getMessages()
实现代码：
