encoding

问题 I have an array that contains values of 1 or 0 representing true or false values. e.g. array(1,0,0,1,0,1,1,1,1); I want to compress/encode this array into the shortest string possible so that it can be stored within a space constrained place such as a cookie. It also need to be able to be decoded again later. How do I go about this? ps. I am working in PHP 回答1: Here is my proposal: $a = array(1,0,0,1,0,1,1,1,1,1,0,0,1,0,1,1,1,1,1,0,0,1,0,1,1,1,1); $compressed = base64_encode(implode('', array

问题 I want to start an external program with an argument which contains German letters, like this: ProcessBuilder pb = new ProcessBuilder("myScript.sh", "argument_with_letters_äöü"); Process p = pb.start(); My JVM (in my case a JBoss AS) is started with encoding ISO 8859-15. The external program 'myScript.sh' however expects UTF-8. Is there a way to send my argument encoded as UTF-8? I serched the web, but didn't find an answer. 回答1: Looking at the code for java.lang.ProcessImpl (the package

问题 I need to export some data using PHP and for each line I'm adding a \r\n . When I open the exported data file that I downloaded, I see that the \r\n is interpreted as [LF] in Notepad. But the application in which I open the file doesn't read the [LF] as a new line. Now if I do a [CR][LF] in Notepad, the application can read the [CR][LF] as a new line. How can I echo the equivalent of [CR][LF] with PHP? 回答1: It's as simple as doing: echo "\r\n"; (note the double quotes) 回答2: Do echo PHP_EOL;
