let's say I have a checkbox search form like this: Check all that interests you: bowling billiard sweets Can I request this data from a database instead of having to resort adding tons of booleans to a database such as this? (VenueId, IfBowling, IfBilliard, IfSweets) And maybe just have one column that would contain all of those options that the venue itself has? Alternative .
假设我有这样的复选框搜索表单: 检查你的所有兴趣: 保龄球 台球 甜食 我可以从数据库中请求这些数据,而不必为这样的数据库添加大量的布尔值吗? (VenueId,IfBowling,IfBilliard,IfSweets) 也许只有一列可以包含场地本身所有的选项? 另类..当然..容易: User表, Interests表, UserInterests表。 UserInterests用于存储Users和Interests之间的多对多关系,并包含来自所述表的FOREGN KEY的值。 PS
I'm changing a website (PHP, MYSQL) to another server, where I'm configuring it in a Linux - Apache environment. The problem is that some pages are displaying character encoding errors. The data is stored in mysql as latin1_swedish_ci , and the php files involved are also encoded in iso-8859-1 . PHPMyAdmin, however, displays this data correctly if I make a query. HTTP headers are show
我正在将一个网站(PHP,MYSQL)更改为另一台服务器,我将其配置到Linux-Apache环境中。 问题是有些页面显示字符编码错误。 数据以latin1_swedish_ci存储在mysql中,涉及的php文件也在iso-8859-1中编码。 但是,PHPMyAdmin,如果我查询,则会正确显示这些数据。 HTTP标头显示“text / html; charset = iso-8859-1”,所以没有错。 我不知道在哪里寻找解决这个问题。 我不知道它是Apache问题还是PHP以某种方式尝试将数据读取
This question already has an answer here: Cannot set content-type to 'application/json' in jQuery.ajax 8 answers I'm afraid that AJAX POST requests must use UTF-8. The jQuery manual explains it: POST data will always be transmitted to the server using UTF-8 charset, per the W3C XMLHTTPRequest standard. You might now wonder about the contentType setting: Note: The W3C XMLHtt
这个问题在这里已经有了答案: 无法在jQuery.ajax中设置content-type为'application / json'8个答案 恐怕AJAX POST请求必须使用UTF-8。 jQuery手册解释了它: 根据W3C XMLHTTPRequest标准,POST数据将始终使用UTF-8字符集传输到服务器。 您现在可能想知道contentType设置: 注意:W3C XMLHttpRequest规范规定字符集总是UTF-8; 指定另一个字符集不会强制浏览器更改编码。 换句话说,你别无选择。 你需要将
I have to deal with encoding for the first time and I'm confused by how PHP, Apache, and browsers handle encodings. PHP and Apache use ISO-8859-1 by default, but most websites are UTF-8. At what point is ISO-8859-1 converted into UTF-8? Also, since PHP uses ISO-8859-1, how come it can read UTF-8 webpages? Apache doesn't "use" any encoding by default, its job hardly has anyt
我不得不第一次处理编码,我很困惑PHP,Apache和浏览器如何处理编码。 PHP和Apache默认使用ISO-8859-1,但大多数网站都是UTF-8。 ISO-8859-1在什么时候转换为UTF-8? 另外,由于PHP使用ISO-8859-1,它怎样才能读取UTF-8网页? Apache在默认情况下不会“使用”任何编码,它的工作与理解或转换文本编码几乎没有任何关系。 PHP默认不会“使用”ISO-8859,PHP的字符串没有相关的编码。 事实是,许多PHP的核心字符串函数在其操作
I've always used ISO-8859-1 encoding, but I'm now going over to UTF-8. Unfortunately I can't get it to work. My MySQL DB is UTF-8, my PHP document is encoded in UTF-8, I set a UTF-8 charset, but it still doesn't work. (it is special characters like æ/ø/å that doesn't work) Hope you guys can help! Make sure the connection to your database is also using this character
我一直使用ISO-8859-1编码,但我现在要转到UTF-8。 不幸的是我无法让它工作。 我的MySQL数据库是UTF-8,我的PHP文档使用UTF-8编码,我设置了一个UTF-8字符集,但它仍然不起作用。 (这是特殊字符,如æ/ø/å不起作用) 希望你们能帮忙! 确保与数据库的连接也使用此字符集: $conn = mysql_connect($server, $username, $password); mysql_set_charset("UTF8", $conn); 根据php.net上的mysql_set_charset的文档: Note

我正在尝试创建一个包含丹麦字符的数组 - 为什么在通过PHP输出时将字符转换为UTF-8?

这个问题在这里已经有了答案: 我应该在MySQL中使用日期时间还是时间戳数据类型? 33个答案 对于我的新数据库,我想保存从PHP到我的数据库的给定日期和时间和年份 因此,将其存储为DATETIME 。 它包括年份。 以下是看这些类型的方法: DATE :用于日期(包含年份),例如aa出生日期(“2010-11-23”) TIME :在一天中使用一段时间,例如午餐开始(“12:00”) DATETIME :用于特定日期和时间,例如会议开始(“2010-
Possible Duplicate: datetime vs timestamp? I would like to know how best to store dates in the database. Do you take a timestamp in the code and save it in an INT field. Do you take a date and format it to correct format and store it in a DATETIME field? What are advantages one way or another? Any good places to read up on the subject? Thanks for you input! I would save the date in
可能重复: 日期时间vs时间戳? 我想知道如何最好地在数据库中存储日期。 你是否在代码中添加了时间戳并将其保存在INT字段中。 你是否采取了一个日期并将其格式化为正确的格式并将其存储在DATETIME字段中? 这种或那种方式有什么优点? 任何有关这个主题的好地方? 感谢您的输入! 我会将日期保存在日期时间字段中,原因如下: 如果您碰巧直接在数据库上工作(调试或其他),您会看到日期格式可读,并且您可以在
This question already has an answer here: Should I use the datetime or timestamp data type in MySQL? 33 answers I'm assuming you're talking about a database table. If that is the case and you need to know date information choose a date time for both modify_date and create_date . If you don't need date information use a time stamp. Depends on your requirements. If you want to
这个问题在这里已经有了答案: 我应该在MySQL中使用日期时间还是时间戳数据类型? 33个答案 我假设你正在谈论一个数据库表。 如果是这种情况,您需要知道日期信息,请为modify_date和create_date选择一个日期时间。 如果您不需要日期信息,请使用时间戳。 取决于你的要求。 如果你想知道这些事情发生的确切时间,那么使用日期/时间(MySQL中的DATETIME)。 或者,如果您对日期感到满意,那么选择日期(MySQL中的DATE
This question already has an answer here: Should I use the datetime or timestamp data type in MySQL? 33 answers You are mixing up client timezone and server timezone. As long as you do not care where your users sit, you have absolutely no problem as long as you do not change the server timezone. You can set a default timezone in MySQL and in PHP and this one will be used, independent of t
这个问题在这里已经有了答案: 我应该在MySQL中使用日期时间还是时间戳数据类型? 33个答案 您正在混合客户端时区和服务器时区。 只要你不关心你的用户在哪里,只要你不改变服务器时区,你就完全没有问题。 您可以在MySQL和PHP中设置一个默认时区,并且将使用此时区,与访问者的时区无关。 如果你想尊重你的访问者的时区,它会变得稍微复杂一些。 您需要将时间戳从一个时区转换为另一个时区。 如果你想用PHP来实现这
