The following editor will bring you a simple method of getting all the file names in the directory and judging the files and directories in PHP. The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let’s follow the editor and take a look.
1. 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。 $handler = opendir('pic/common');
2. Loop to read all files in the directory
Code example:
/*其中$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 $filename; } }
3. Close the directory
Code example:
closedir($handler);
2, PHP file and directory judgment function
<?php //检查上级目录下的目标对象logo.jpg是否是文件。 $checkResult = is_file('../logo.jpg');
Description: If the target object is a file, the system returns true, otherwise it returns false.
Code example:
<?php //检查上级目录下的目标对象logo.jpg是否是目录。 $checkResult = is_dir('../logo.jpg');
Description: Returns true if the target object is a directory system, otherwise returns false.
