php File Handling-How to read files (one line, whole file)
Reading and writing files is more complex than opening and closing files. This is mainly from reading data and writing data two aspects of the explanation.
So in the previous article, "PHP file processing-open and close files" describes the open and close file
In my previous blog, I described how to use files in JavaScript, with a specific focus on how to get the file object. Only when the user uploads the file by uploading or dragging it, these objects have the metadata of the file. Once you have these files, the next step is to read the data from these files.FileReader typ

A programming case Introduction
This case is based on the console project, create a specialized demo class CDemo, realize the binary file read and write serialization operation, the specific code is as follows:
1 CDemo class Definition:

void CreateFile ();
CDemo ();
Virtual ~cdemo ();
void Serialize (CArchive ar);
void WriteFile ();
void ReadFile ();

PHP file read operations involve more PHP file manipulation functions than file writes, which are described in detail in code instances.
The way in which data is stored in a text file is mainly three steps and some file operation
PHP (foreign name: Hypertext Preprocessor, Chinese name: "Hypertext Preprocessor") is a common open source scripting language. Grammar absorbs the C language, Java and Perl features, the entry threshold is low, easy to learn, widely used, mainly for the field of web development. PHP has a file suffix called PHP. This article is for you to explain the concurrency of the PHP file conflict resolution (

Note: Due to typographical issues, correct the changes now.

First, create a file output stream object whose value is equal to the return value of the context call openfileoutput () met
1. after open is used to open a file, remember to call the close () method of the file object. For example, you can use the tryfinally statement to ensure that the file can be closed at last. File_objectopen(thefile.txt) try: all_the_textfile_object.read () finally: file_object.close () Note: The open statement cannot be placed in the try block, because when the
For security reasons, it's a good idea to specify a name for the open file object so that you can close the file quickly after the operation is complete, preventing some useless file objects from taking up memory. For example, read from a text file:File_object = open (' Thefile.txt ')TryAll_the_text = File_object.read
Files from resources and assets can only be read and cannot be written.
The files in the assets folder are kept in the original file format, and you need to read the files in Assetmanager as a byte stream.
1. Call Getassets () first in the activity to get the Assetmanager reference.
2. The Assetmanager open (String fileName, int accessmode) method specifies th
For security reasons, it's a good idea to assign a name to an open file object so that you can quickly close the file to prevent unwanted file objects from consuming memory after you complete the operation. For example, read a text file:
File_object = open (' thefile
