PHP has a lot of file system-related functions, not only can help you open the file, you can also display the contents of the directory, mobile files and so on. Many people even use PHP to write a web-based file manager.
First you need to remind you of something about the file path: In Windows you can use a slash "/" or a backslash "\" in the file path, while the other operating system uses only "/". For compatibility reasons, the following example uses the representation of "/":
The following simple script shows a basic list of directories. Comments are in the code and explain each step:
? * * Give the full path of the directory you want to access in the variable $dir _name * *
$dir _name = "/home/me/";
/* Create a handle to open the result of a given directory
$dir = Opendir ($dir _name);
/* Start a piece of text to add to the place where the list element (file name) will be placed * *
$file _list = "<ul>";
/* Use the while statement to read all the elements of the Open directory. If the file name is not "." and ".." The file name is printed in the list.
while ($file _name = Readdir ($dir)) {
if ($file _name!= ".") && ($file _name!= "...")) {
$file _list. = "<li> $file _name";
}
}
/* END LIST * *
$file _list. = "</ul>";
