<?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。

<?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。

<?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!

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 ); } |

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。

要实现其中的两个方法,一个是isValid(),一个是getMessages()

<?php require_once "Zend/Validate/Interface.php" ; class MyValidator implements Zend_Validate_Interface{ protected $_messages = array (); public function isValid( $value ){ $this ->_messages = array (); $requirement = !( $value %3); if (! $requirement ){ $this ->_messages[] = "'$value'不能被3整除" ; return false; } return true; } public function getMessages(){ return $this ->_messages; } } function c_n_3( $n ){ $validator = new MyValidator(); if ( $validator ->isValid( $n )){ echo "指定的数值:" ; echo $n . ",是3的倍数!<p>" ; } else { echo "指定的数值:" ; echo $n . ",不是3的倍数!<p>" ; echo "失败的消息为:<p>" ; foreach ( $validator ->getMessages() as $message ) { echo "$message<p>" ; } } } $num1 = 5; $num2 = 6; $num3 = 8; c_n_3( $num1 ); c_n_3( $num2 ); c_n_3( $num3 ); |
结果:
指定的数值:5,不是3的倍数!
失败的消息为:
'5'不能被3整除
指定的数值:6,是3的倍数!
指定的数值:8,不是3的倍数!
失败的消息为:
'8'不能被3整除
点评:
这里通过isValid()方法来设置属性信息,通过getMessages()方法来获取错误消息。错误消息是一个数组,通过foreach()方法来遍历读取。
希望本文所述对大家基于Zend Framework框架的PHP程序设计有所帮助。
