Possible Duplicate: php date compare I have a date that I take from the mySQL database that looks like this: 2011-06-20 And I get the date of the current day in this way: $todaydate = date('Y-m-d'); What I need to know is how do I compare the two results? How can I compare the dates and understand for example if a week is passed from the database date or a month or a year..etc..? Thank you!! There is no need to put that burden on PHP when MySQL has built-in functionality for that already. You should take a look at MySQL's DATEDIFF() function: DATEDIFF() returns expr1 – expr2 expressed as a

I'm wondering how I can compare 1 element of a vector with all elements in the other vector. As an example: suppose x <- c(1:10) y <- c(10,11,12,13,14,1,7) Now I can compare the elements parewise x == y [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE But I want to compare all elements of y with a specific element of x, something like x[7] == y [1] FALSE TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE Is this possible? Do you mean something like this? x <- 1:10 y <- c(10,7,11,12,13,14,15,16,17,18) res <- outer(x, y, `==`) colnames(res) <- paste0("y=", y) rownames(res) <-

I am stuck in comparing two unicode strings in PHP which both contain the special char 'ö'. One string comes from $_GET , the other one is a filesystem's folder name ( scandir() ). Both strings seem to be equal to me, making a var_dump($filter); var_dump($tail . '/' . $k); on them also shows their equality but with different string lenghts (?!): string '/blöb' (length=7) string '/blöb' (length=6) My snippet comparing them looks as follows: if($filter == ($tail . '/' . $k)) { /* ... */ } What's going on here? Additional information: $tail is an empty string: string '' (length=0) See here: http:

十六进制由0-9，A-F组成，字母不区分大小写，与10进制的对应关系是：0-9对应0-9；A-F对应10-15；N进制的数可以用0~(N-1)的数表示，超过9的用字母A-F。一般情况下，十六进制文件颇为复杂，如果想通过肉眼查找文件之间的差异是十分困难的。现在可以使用Beyond Compare可以帮助您轻松搞定十六进制文件的对比工作，软件比较功能强大，性能优越，接下来主要和大家分享使用 Beyond Compare 执行十六进制比较会话时，查看当前字节地址的方法。 具体操作步骤如下所示 步骤一：打开Beyond Compare软件，在主页面左侧新建会话目录中选择“16进制比较“会话，打开会话操作界面。此外您也可以直接选中需要比较的两份十六进制文件，右键文件并在展开的菜单中选择”比较“选项。 Beyond Compare十六进制比较会话界面图例 步骤二：在打开的十六进制比较会话左侧或者右侧窗格中，将光标停留在您需要查看某个字节地址的位置，单击比较会话菜单栏“视图”按钮并在展开的菜单中查看字节地址，如下图图例所示。 Beyond Compare十六进制比较查看当前字节地址图例 步骤三：如果您想要查看正在比较的十六进制文本文件的整体字节地址，需单击视图菜单中的“字节地址“选项，即可分别在左右两侧会话窗格中显示字节地址，如下图图例所示。 Beyond
