How to read all file names in php

php gets all the file names in the directory

1. Open the directory handle of the directory to be operated

Code example:

//打开当前目录下的目录pic下的子目录common。 $handler = opendir('pic/common');

2. Loop through all files in the directory

Code example:

/*其中$filename = readdir($handler) 每次循环时将读取的文件名赋值给$filename，$filename !== false。 一定要用!==，因为如果某个文件名如果叫'0′，或某些被系统认为是代表false，用!=就会停止循环 */ while( ($filename = readdir($handler)) !== false ) { //略过linux目录的名字为'.'和‘..'的文件 if($filename != “.” && $filename != “..”) { //输出文件名 echo $filename; } }

3. Close the directory

Code sample:

closedir($handler);
