opendir

问题 I'm a beginner and I am making a code about getting the directory of a file, but I have something that I don't understand. What's the meaning of "./" in DS = opendir ("./"); I have searched a lot of sites about C programming, but nothing gave me a good explanation. I have to present my code soon, forcing me to explain every single line of my code. Please help me. Thanks! 回答1: ./ is a relative path which is relative to the current working directory of your process. In computing, the working

问题 I'm using the following PHP code to list all files and folders under the current directory: <?php $dirname = "."; $dir = opendir($dirname); while(false != ($file = readdir($dir))) { if(($file != ".") and ($file != "..") and ($file != "index.php")) { echo("<a href='$file'>$file</a> <br />"); } } ?> The problem is list is not ordered alphabetically (perhaps it's sorted by creation date? I'm not sure). How can I make sure it's sorted alphabetically ? 回答1: The manual clearly says that: readdir

问题 Salutations, Elders of code, I am on a quest to master the spells of PHP, and now need your assistance in slaying a mighty beast. I'm making a REST API in PHP. One of the functions is a GET that returns a list of pngs in a dir. But instead of returning one array, it returns multiple arrays (one for each iteration?). I want: ["1.png","2.png","3.png"] But I'm getting: ["1.png"]["1.png","2.png"]["1.png","2.png","3.png"] I present my pitiful function for scorn and humiliation: function getPics()

问题 i've been trying to figure out why my Php code is giving me a annoying error. I've tried countless functions from previous post but the error its been giving is "Permission Denied". From my understanding either i have to have special privledges to delete files, etc.. I've tried multiple solutions but I'm still getting this error. If anyone can point me in the right direction, that'll be great. Ive post a snippet of my code below.. Thanksss $first_sub = "my_dir"; if(is_dir($first_sub)){ $read

问题 I have a folder called allfiles , and there are some files in this folder, such as 1212-how-to-sddk-thosd.html 3454-go-to-dlkkl-sdf.html 0987-sfda-asf-fdf-12331.html 4789-how-to-fdaaf-65536.html I use scandir to list all files, and now I need to find the file by with keywords, example to-dlkkl is the keyword, and I will get the file 3454-go-to-dlkkl-sdf.html . Glob seems not work, and opendir and readdir are not work well, any ideas? 回答1: Use loop foreach and strpos function: $files = scandir

问题 I have a directory full of files that I am trying to echo out. If the file is an image, the image itself is echoed out. If the file is not an image, the name of the file is echoed out. This code below works perfectly however I can't seem to get the order sorted by date. The files are randomly echoed out. How would I make it so that the files are sorted by last modified (latest first). <?php $blacklist = array("index.php"); $ext = pathinfo($files, PATHINFO_EXTENSION); if ($handle = opendir('.'

问题 I cannot get this function to work, because for some reason opendir will not take buffer2 (declared as char buffer2[128]) as an argument properly. If I replace the variable with something like "." or "sample", it works perfectly. But doing it like this, I get a segmentation fault every time. Please help. system("clear"); DIR *dirp; struct dirent *dp; printf("Enter directory name: "); fgets(buffer2, 100, stdin); if((dirp = opendir(buffer2)) == NULL) printf("Could not open directory\n"); while(
