对于一个严格的web开发流程来说,任何一个表单提交的动作都必须经过严格的格式验证,不仅需要在客户端进行js验证,在服务器端用程序进行二次验证是必不可少的。
下面与大家分享一个php格式的服务器端的表单字段格式验证的一个类。
具体的代码如下:
<p><?php</p>/*<br />* author:www.scutephp.com<br />* time:2012-3-31 17:35:42<br />* function:php表单字段格式验证<br />*/<br />class verification{<br /> //验证字符串长度是否在指定范围内[这里只验证半角状态下输入的字符]<br /> function fun_length($str,$min,$max){<br /> return (strlen($str)>$max||strlen($str)<$min)?false:true;<br /> }<br /> //验证是否为指定长度的字母/数字组合 <br /> function fun_text1($num1,$num2,$str){<br /> return (preg_match("/^[a-za-z0-9]{".$num1.",".$num2."}$/",$str))?true:false;<br /> }<br /> //验证是否为指定长度数字 <br /> function fun_text2($num1,$num2,$str){<br /> return (preg_match("/^[0-9]{".$num1.",".$num2."}$/i",$str))?true:false;<br /> }<br /> //验证是否为指定长度汉字 <br /> function fun_font($num1,$num2,$str){<br /> return (preg_match("/^([\x81-\xfe][\x40-\xfe]){".$num1.",".$num2."}$/",$str))?true:false;<br /> }<br /> //验证邮件地址 <br /> function fun_email($str){ <br /> return (preg_match('/^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,4}$/',$str))?true:false;<br /> }<br /> //验证电话号码 <br /> function fun_phone($str){<br /> return (preg_match("/^1[358][0123456789]\d{8}$/",$str))?true:false;<br /> }<br /> //验证手机号码<br /> function fun_mobile($str){<br /> return (preg_match("/^(((d{3}))|(d{3}-))?((0d{2,3})|0d{2,3}-)?[1-9]d{6,7}$/",$str))?true:false;<br /> }<br /> //验证邮编 <br /> function fun_zip($str){<br /> return (preg_match("/^[1-9]d{5}$/",$str))?true:false;<br /> }<br /><p>}</p>
以上类的使用方法这里就不再举例说明了。
