My question is, where does WordPress get the data from relating to automatic Timezone and DST change and how can I implement the same principal into converting a web app users selected local date and time into stored offsets to allow for their movement back and forward of clocks during daylight saving? Obviously I can store this as UTC and then convert the time to their local Timezone on the fl
我的问题是,WordPress从哪些地方获得与自动时区和DST变化相关的数据,以及如何实现相同的委托人将用户选择的本地日期和时间转换为存储的偏移以允许他们移动时钟的前后移动在夏令时? 很显然,我可以将它存储为UTC,然后将时间转换为当地时区,但如果它们在创建记录时处于相反的夏令时设置中,它仍不能准确反映它们输入的日期和时间。 我正在使用asp.net c#与sql服务器。 WordPress通过选择一个城市自动反映夏令时,而不是
Hi I want to get tags of video from youtube video url, I have searched in google but mostly I get answer that "YouTube's API can no longer be used to retrieve tags". So is there any way that I can get video tags from youtube video using php or any api? For example for URL : http://www.youtube.com/watch?v=LIjs3-8cZVA $connect = file_get_contents("http://www.youtube.com/watch?v=L
您好我想从YouTube视频网址获取视频标签,我已经在谷歌搜索,但主要是我得到的答案是“YouTube的API不能再用于检索标签”。 那么有什么方法可以使用php或任何api从YouTube视频获取视频标签? 例如URL:http://www.youtube.com/watch?v = LIjs3-8cZVA $connect = file_get_contents("http://www.youtube.com/watch?v=LIjs3-8cZVA"); preg_match_all('|<meta property="og:video:tag" content="(.+?)">|si', $connect, $
Every now and then I hear the advice "Use bcrypt for storing passwords in PHP, bcrypt rules". But what is bcrypt ? PHP doesn't offer any such functions, Wikipedia babbles about a file-encryption utility and Web searches just reveal a few implementations of Blowfish in different languages. Now Blowfish is also available in PHP via mcrypt , but how does that help with storing pass
我偶尔会听到“使用bcrypt在PHP中存储密码,bcrypt规则”的建议。 但是什么是bcrypt ? PHP不提供任何这样的功能,维基百科关于文件加密实用程序的喋喋不休,Web搜索只是揭示了几种不同语言的Blowfish实现。 现在Blowfish也可以通过mcrypt以PHP方式获得,但这对于存储密码有什么帮助? 河豚是一种通用密码,它有两种工作方式。 如果它可以被加密,它可以被解密。 密码需要单向散列函数。 什么是解释? bcrypt是一种散列
I know that PHP doesn't have native Enumerations. But I have become accustomed to them from the Java world. I would love to use enums as a way to give predefined values which IDEs' auto completion features could understand. Constants do the trick, but there's the namespace collision problem and (or actually because) they're global. Arrays don't have the namespace problem,
我知道PHP没有本地枚举。 但是我已经习惯了来自Java世界的他们。 我很乐意使用枚举作为给出IDE自动完成功能可以理解的预定义值的方式。 常量可以做到这一点,但是有名称空间冲突问题和(或者实际上是因为)它们是全局的。 数组没有名称空间问题,但是它们太模糊,在运行时可能会被覆盖,而IDE很少(从不?)知道如何自动填充它们的密钥。 有没有通常使用的解决方案/解决方法? 有没有人记得PHP的人是否对枚举有任何想法
PHP treats all arrays as associative, so there aren't any built in functions. Can anyone recommend a fairly efficient way to check if an array contains only numeric keys? Basically, I want to be able to differentiate between this: $sequentialArray = array('apple', 'orange', 'tomato', 'carrot'); and this: $assocArray = array('fruit1' => 'apple', 'fruit2' => 'or
PHP将所有数组视为关联,因此没有任何内置函数。 任何人都可以推荐一种相当有效的方法来检查一个数组是否只包含数字键? 基本上,我想能够区分这一点: $sequentialArray = array('apple', 'orange', 'tomato', 'carrot'); 和这个: $assocArray = array('fruit1' => 'apple', 'fruit2' => 'orange', 'veg1' => 'tomato', 'veg2' => 'carrot')
So I've implemented PayPal fully into my system. The system works on user 'packages', all at set prices. Each user has a subscr_id (set by PayPal) assigned to them, along with details of the package they've bought. I need to be able to modify the subscription so the user can select a different package. Essentially I just need to be able to change the amount and the 'custo
所以我已经将PayPal完全实施到了我的系统中。 该系统在用户'包'上工作,全部以定价。 每个用户都有一个分配给他们的subscr_id(由PayPal设置),以及他们购买的软件包的详细信息。 我需要能够修改订阅,以便用户可以选择不同的包。 基本上我只需要能够改变金额和'自定义'字段(这包含包详细信息,使用的优惠券等)。 我会想,并且希望它能够像为用户显示'修改','subscr_id','自定
A client of mine decided to move the website from a somewhat nice server to a... lets call it lesser nice server. The problem is, there's a file with 40MBs to be downloaded and the memory limit on the server is 32. To make it even more difficult for me, they don't allow fopen... Also, if i reduce the file size to 20MB it works fine. So, my question is, what can i do - besides reduci
我的一个客户决定将网站从一个不错的服务器移动到...让我们称之为更好的服务器。 问题是,有一个40MB的文件需要下载,而服务器上的内存限制是32个。为了让我更加困难,他们不允许fopen ... 此外,如果我减小文件大小为20MB它工作正常。 所以,我的问题是,除了缩小文件大小外,我还能做些什么? 谢谢 编辑:` $fsize = filesize($file_path); $path_parts = pathinfo($file_path); $ext = str
I need to catch some warnings being thrown from some php native functions and then handle them. Specifically: array dns_get_record ( string $hostname [, int $type= DNS_ANY [, array &$authns [, array &$addtl ]]] ) It throws a warning when the DNS query fails. try / catch doesn't work because a warning is not an exception. I now have 2 options: set_error_handler seems lik
我需要捕捉一些来自一些PHP本地函数的警告,然后处理它们。 特别: array dns_get_record ( string $hostname [, int $type= DNS_ANY [, array &$authns [, array &$addtl ]]] ) 它在DNS查询失败时引发警告。 try / catch不起作用,因为警告不是例外。 我现在有2个选项: set_error_handler似乎是过度杀伤性的,因为我必须使用它来过滤页面中的每个警告(这是真的吗? 调整错误报告/显示,以便这些警告
I find programming in PHP quite frustrating. Quite often I will try and run the script and just get a blank screen back. No error message, just empty screen. The cause might have been a simple syntax error (wrong bracket, missing semicolon), or a failed function call, or something else entirely. It is very difficult to figure out what went wrong. I end up commenting out code, entering "
我发现用PHP进行编程非常令人沮丧。 很多时候我会尝试运行脚本,然后回到空白屏幕。 没有错误信息,只是空的屏幕。 原因可能是一个简单的语法错误(错误的括号,缺少分号),或失败的函数调用,或完全是其他的东西。 弄清楚哪里出了问题是非常困难的。 我最终评论了代码,在各处输入“回声”声明等等,试图缩小问题的范围。 但是肯定有更好的方法,对吧? 那么,有没有办法让PHP像Java那样产生有用的错误信息呢? 任何人
How can I write two functions that would take a string and return if it starts with the specified character/string or ends with it? For example: $str = '|apples}'; echo startsWith($str, '|'); //Returns true echo endsWith($str, '}'); //Returns true function startsWith($haystack, $needle) { $length = strlen($needle); return (substr($haystack, 0, $length) === $needle); } function ends
我该如何编写两个函数,如果它以指定的字符/字符串开头或者以它结束,则返回一个字符串并返回? 例如: $str = '|apples}'; echo startsWith($str, '|'); //Returns true echo endsWith($str, '}'); //Returns true function startsWith($haystack, $needle) { $length = strlen($needle); return (substr($haystack, 0, $length) === $needle); } function endsWith($haystack, $needle) { $length = strlen(
