This article mainly introduces the feof () function instance test in PHP. if you need it, you can refer to the example in this article to describe the usage of the feof () function in PHP () function tests are very useful. The specific analysis is

PHP File processing advanced application-file pointer php can implement the positioning of the file pointer and query, so as to achieve the required information fast query, the file pointer function has rewind (), fseek (), feof () and Ftell ()

( Article Category "C/C ++", but there are only basic instructions, for fear of forgetting in the future. Take a look at the relative details of this article and leave a memo) C language file operation functions Category: C/C13.1c language file1.

File operations are required for every language, not just PHP, here we only use PHP to explain PHP file Advanced operations and file upload examples I put in the last part of the article. --I will also write a php similar to the operation of the

Fseek (read/write location of a mobile file Stream)Related functions: rewind, ftell, fgetpos, fsetpos, and lseek Header file # include  Defines the int fseek (FILE * stream, long offset, int whence) function ); Function Description: fseek () is used

Section 10. 1 C Overview File is an important concept in programming. A file is a collection of data stored on an external media. A batch of data is stored in external media (such as disks) as files. The operating system manages data in files. That

HTTP resumable upload Principle:1. Open the local file fopen and move the file pointer to the end of the file fseek2. Get the file size ftell and format the HTTP Request Header "range: bytes = ftell-" to offset the httpfile pointer to implement

I. fflush 1. The fflush prototype is as follows: Int fflush (File * stream ); 2. When you need to physically write the data in the output buffer immediately, you should use this function. For example, the fflush function is called to ensure that

File operation. 2007-03-24 00:55 @ Function Name: FputcharFunction prototype: int fputchar (int ch)Function: Writes a character to the current position of the standard output stream (that is, on the screen)function returns: Returns the

Check it out. It is easy to realize the function of file operation function of the same C language. The functions that are used in the functions that you implement are only Fseek and Ftell. Their descriptions are as follows: Fseek Grammar:

C Language File Operation resolution There are several more common operations in file operations, in addition to open operations and read and write operations. Here's a description of the functions involved in these operations. I. Function to move
