First, the principle. A camel looked at so much information, found that no matter what method, the principle is the same. is to use the program to read the corresponding data to replace the variables in the template, and then generate a static page.

PHP Implementation file security download The procedure is as follows: $file_name = "Info_check.exe"; $file_dir = "/public/www/download/"; if (!file_exists ($file_dir. $file_name)) {//check whether the file exists echo "File not found"; Exit } else {

A simple php file download source code, although does not support the extension of the breakpoint, but can meet some common needs. PHP download file in fact with a tag can be implemented, such as magento-1.8.1.0.zip. But some browsers can recognize

Using PHP not only allows users to access server-side files through the browser, but also access files from other servers via protocols such as HTTP or FTP, and can use HTTP and FTP URLs instead of filenames in most functions that require a filename

PHP implementation file Security download The procedure is as follows: The following are the referenced contents: $file_name = "Info_check.exe"; $file_dir = "/public/www/download/"; if (!file_exists ($file_dir. $file_name)) {//check

To save the custom data File, you need to save the File and read the File, that is, File IO processing; For cocos2d-x we can through FileUtils: getInstance To save the custom data File, you need to save the File and read the File, that is, File IO

Sometimes we need to use php to download some files. This is generally required to hide the files. Otherwise, it will increase the burden on the server. It is better to provide the software address directly. Sometimes we need to use php to download

First, determine whether the folder exists:1. Use CreateDirectory (".//filemanege", NULL), or create if the folder Filemanege does not exist.2. Or if (_access (".//filemanege", 0) ==-1), indicates that Filemanege does not exist.3. or bool

The cocos2d-x provides the getfiledata interface as follows: Char * file = (char *) ccfileutils: sharedfileutils ()-> getfiledata ("testjson. JSON", "r", & size ); Other methods are as follows: With reference to other people's programs, the path is

C language is more suitable for operating hardware and is more efficient in some file processing operations, so similar operations generally use JNI to call C code for operations: such as audio, video and image processing: For example, in audio
