fopen

问题 I'm trying to make my PHP script open more than 1 text document and to read them. My current script is as follows: <?php //$searchthis = "ignore this"; $matches = array(); $FileW = fopen('result.txt', 'w'); $handle = @fopen("textfile1.txt", "r"); ini_set('memory_limit', '-1'); if ($handle) { while (!feof($handle)) { $buffer = fgets($handle); if(stripos($buffer, $_POST["search"]) !== FALSE) $matches[] = $buffer; } fwrite($FileW, print_r($matches, TRUE)); fclose($handle); } ?> I'm trying to

问题 I am trying to read a text file with data according to a specific format. I am using and textscan together with a string containing the format to read the whole data set in one code line. I've found how to read the whole line with fgetl , but I would like to use as few code lines as possible. So I want to avoid own for loops. textscan seems great for that. As an example I'll include a part of my code which reads five strings representing a modified dataset, its heritage (name of old dataset),

问题 I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch! 回答1: there's a method MakeSureDirectoryPathExists in the windows API, declared in dbghelp.h. It recursively creates directories, so

问题 I am trying to initialize a multidimensional array from a file using C for a iPhone 4inch app but I can't open up the file using fopen . Whenever I try this I get a NULL : FILE *f; f=fopen("/level1.rez", "r"); if (f == NULL) { printf("Error Reading File\n"); //exit (0); } I am not sure how to open files using C . I tried this already: I printed out the current working directory using getcwd but all I got was "/" and when I attached that to the file name I still got NULL . I read that if you

问题 I am having a problem saving a file using fopen. For some reason the saved file has a question mark in the end. I am attempting to retrieve a list of files from a remote server and download them to my server. This is the part of my code that does the job : $arrlength = count($reports); for ($x = 0; $x < $arrlength; ++$x) { $report = $reports[$x]; $thefilepath = returnfilename($report); echo 'the filepath : '.$thefilepath; echo '<br>'; $thefilename = basename($thefilepath).PHP_EOL; echo 'the

问题 In reading the documentation for php fopen for php I see the following: For portability, it is strongly recommended that you always use the 'b' flag when opening files with fopen(). What is the b flag and what does it do ? Why is it strongly recommended ? 回答1: The 'b' flag forces binary mode. You use the 'b' flag if you want to deal with binary files, ie. an image. Note: When you write a text file and want to insert a line break, you need to use the correct line-ending character(s) for your

问题 I am using Visual Studio 2005 (C\C++). I am passing a string into a function as a char array. I want to open the file passed in as a parameter and use it. I know my code works to an extent, because if I hardcode the filename as the first parameter it works perfectly. I do notice if I look at the value as a watch, the value includes the address aside the string literal. I have tried passing in the filename as a pointer, but it then complains about type conversion with __w64. As I said before

问题 I'm on Windows XP using Visual Studio 6 (yes I know it's old) building/maintaining a C++ DLL. I'm encountered a problem with fopen failing to open an existing file, it always returns NULL. I've tried: Checking errno and _doserrno by setting both to zero and then checking them again, both remain zero, and thus GetLastError() reports no errors. I know fopen isn't required to set errno when it encounters an error according to a C standard. Hardcoding the file path, which are not relative. Tried

问题 how can i inlude a class file from my parent domain to be used in a subdomain on my server? for example, I have a class file that handles user authentication along with some important methods. How can I use that authentication class on a subdomain? my folder structure is parent domain /home/<domain>/public_html/ subdomain /home/<domain>/public_html/users/cluster_1/<sub> When I make a new subdomain I have a template index.php that is copied onto the /home/<domain>/public_html/users/cluster_1/

问题 I would like to open 2 url's using open $url = 'http://xtreme-jumps.eu/demos.txt'; $url2 = 'http://cosy-climbing.net/demoz.txt'; Something like this... but it's not working $handle = @fopen($url, "r"); $handle .= @fopen($url2, "r"); I need to join them because later i'll search there if ($handle) { while (!feof($handle)) { $buffer = fgets($handle); if(strpos($buffer, $map) !== FALSE) $matches[] = $buffer; } fclose($handle); } Thanks 回答1: You could try something like this: $handles=array();
