The meaning of the offset parameter in the ##################### #read () function
Read (FILEHANBD, $var, $length, $offset)
The read function has four parameters, most easily misunderstood is the $offset
It means to look at the official document and explain:
An OFFSET may is specified to place the read data at some place in the string other than the beginning. A Negative OFFSET Specifies placement at this many characters counting backwards from the end of the string. A positive OFFSET greater
Node's Glob module allows you to write a glob rule using * and other symbols, like in the shell, to get files that match the corresponding rules.
This Glob tool is based on JavaScript. It uses the Minimatch library to match

1. glob is a python file operation module. It can be used to find files that match your own purposes. It is similar to file search in windows and supports wildcard operations ,*,?, [] These three wildcards * represent 0 or multiple characters ,? Represents a character. [] matches a character in the specified range, for example, [0-9] matches a number.
Its main method is glob, which returns the list
Python linecache, glob module, linecacheglob
Today I learned two interesting modules: linecache and glob.
Linecache Module
In python, there is a handy module linecache, which allows any row from any file and is optimized using the cache. It is common to read multiple lines from a single file.
# From the linecache name, we can know that this module is related to the cache.
# Linecache reads the file into
This article mainly introduces how to use the glob module in Python to find the file path. it is very simple to use the iglob method in the module, if you need it, refer to the glob module, which is one of the simplest modules with very little content. You can use it to find the path name of a file that complies with specific rules. It is similar to searching files in windows. Only three matching characters

This example describes how PHP uses the Glob function to traverse a directory or folder. Share to everyone for your reference. The specific analysis is as follows:
When it comes to PHP traversal directory Many of our friends will think of Opendir and Readdir, so that you can traverse the directory and display files, but in PHP there is a more concise traversal of the directory function Glob estimated that
#glob文件名模式匹配#作用: Use Unix shell rules to find matching file names with a pattern"""Although the Glob API is small, this module is very powerful, as long as the program needs to find a file system in which the name matches a set of files in a certain pattern.You can use this module to create a list of file names that require each file name to have a specific extension, a prefix, or a common string in the mid
Traversing all files under a folder, you can generally use the Opendir and Readdir methods to traverse.
Example: Find all the PHP files in the specified directory (do not search subfolders), the code is as follows:
$path = dirname(__FILE__);$result = traversing($path);print_r($result);functiontraversing($path){$result = array(); if($handle = opendir($path)){ while($file=readdir($handle)){ if($file!='.' $file!='..'){ if(strtolower(substr($file, -4)
