I must do a little trick for a site! The idea is: if a file for a required url exists then I go to that url, doing nothing more; if a file for a required url not exists, I must go to a file.php and than do something, but NOT changing the url! example: www.mysite.com/page1.htm -> exists -> go to file page1.htm www.mysite.com/page2.htm -> NOT exists -> go to file default.php but with url "www.mysite.com/page2.htm" It's possible to do this all by .htaccess? user237419 RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^.*$ /default.php [L] It is

Why does 'File.exists' return true, even though 'Files.exists' in the NIO 'Files' class returns false

问题 I am trying to determine if a file exists in a network folder: // File name is "\\QWERTY\folder\dir\A123456.TXT" Path path = Paths.get("\\\\QWERTY\\folder\\dir\\A123456.TXT") Using NIO Files : Files.exists(path) == false Using File : path.toFile().exists() == true Using File seems to be the correct one according to our tests. Why does File work better than Files ? So, which is it? Can't be both! But wait, there is also Files.notExists(path) . When the network share file actually exists Files

For some reason this PHP code below will not work, I can not figure it out. It is very strange, file_exists does not seem to see that the image does exist, I have checked to make sure a good file path is being inserted into the file_exists function and it is still acting up If I change file_exists to !file_exists it will return an images that exist and ones that do not exist define('SITE_PATH2', 'http://localhost/'); $noimg = SITE_PATH2. 'images/userphoto/noimagesmall.jpg'; $thumb_name = 'http://localhost/images/userphoto/1/2/2/59874a886a0356abc1_thumb9.jpg'; if (file_exists($thumb_name)) {

Check if a file exists before calling openFileInput

问题 To read a file in Android from your app's private storage area you use the function openFileInput() . My question is, is there a way to check if this file exists before calling this function? The function can throw a FileNotFoundException , but I feel like calling this and then doing something based on a try - catch is a bad practice. Using File.exist() seems like a strange thing to use also since it would require instantiating a class and I am not sure if just passing the name of the file to

问题 if (!(file_exists(http://mysite.com/images/thumbnail_1286954822.jpg))) { $filefound = '0'; } why won't this work? 回答1: if (!file_exists('http://mysite.com/images/thumbnail_1286954822.jpg')) { $filefound = '0'; } 回答2: The function expects a string. file_exists() does not work properly with HTTP URLs. 回答3: file_exists checks whether a file exist in the specified path or not. Syntax: file_exists ( string $filename ) Returns TRUE if the file or directory specified by filename exists; FALSE

问题 I need to check if a file exists but I don't know the extension.

How to check if a file exists from a url

由 不想你离开。 提交于 2019-11-26 20:05:54
I need to check if a particular file exists on a remote server. Using is_file() and file_exists() doesn't work. Any ideas how to do this quickly and easily? Amila You have to use CURL function does_url_exists($url) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_NOBODY, true); curl_exec($ch); $code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($code == 200) { $status = true; } else { $status = false; } curl_close($ch); return $status; } You don't need CURL for that... Too much overhead for just wanting to check if a file exists or not... Use PHP's get_header . $headers=get_headers($url); Then
