本文实例讲述了php常用表单验证类用法。分享给大家供大家参考。具体如下：
<"/^[a-zA-Z0-9]{".$num1.",".$num2."}$/",$str))"/^[0-9]{".$num1.",".$num2."}$/i",$str))"/^[\xa0-\xff]{1,4}$/", $string);
return (preg_match("/^([\x81-\xfe][\x40-\xfe]){".$num1.",".$num2."}$/",$str))"/^((\(\d{3}\))|(\d{3}\-))",$str))"/^[1-9]\d{5}$/",$str))"/^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\"\"])*$/",$str))" "," ",$data[$k1][$k2]);
$data[$k1][$k2]=str_replace("\n","<br>\n",$data[$k1][$k2]);
}
}
else
{
$data[$k1]=nl2br(htmlspecialchars($data[$k1]));
$data[$k1]=str_replace(" "," ",$data[$k1]);
$data[$k1]=str_replace("\n","<br>\n",$data[$k1]);
}
}
}
else
{
$data=nl2br(htmlspecialchars($data));
$data=str_replace(" "," ",$data);
$data=str_replace("\n","<br>\n",$data);
}
Return $data;
}
}
?>
希望本文所述对大家的php程序设计有所帮助。
