How to Get File Information in PHP

How to get file information in php - A file certainly has information about the file. Such file information such as file size, file type, file creation time and others. For that reason in this article I will submit a tutorial on how to get file information in php.
Some functions related to file information and manipulation are listed in the table as follows:

Function	Information
file_exists($file)	Check if $file exists or not
is_file($file)	Check if $file is a file or not.
is_dir($file)	Check if $ file is a directory or not.
is_executable($file)	Check if $ file includes files that can be run directly or not.
is_writable($file)	Check if $ file includes files that can be written or edited.
is_readable($file)	Check if $ file includes a readable file or not.
fileatime($file)	Generates the last access time of the file (unix timestamp).
filectime($file)	Generates file creation time (unix timestamp).
filemtime($file)	Generates the last modification time of the file (in unix timestamp).
filesize($file)	Generate large file size (in bytes).
filetype($file)	Generate file types.

To be able to understand more, here I give examples of programs to Get File Information using php.
Program 1
File Name: file11.php
Description: The program checks for the existence of a file.
Type the following php code into notepad.
<?php
$filename = "data.txt";

if (file_exists($filename)) {
echo "File $filename THERE IS";
} else {
echo "File $filename THERE IS NO";
}
?>

Save the php code with file11.php name in the htdocs folder. To run the program open the browser then type http://localhost/file11.php in the address bar then enter. The result will look like the following.

In windows explorer the file exists

Program 2
File Name: file12.php
Description: The program gets some file information.
Open notepad type the following php code.
<?php
$file = "data.txt";

if (is_file($file)) {
 echo "File <b>$file</b> Is FILE<br>"; 
 //
 if (is_executable ($file)) {   
 echo "File <b>$file</b> Can be run directly (executable)<br>";
 } else {   
 echo "File <b>$file</b> NO executable<br>"; 
 }
//
 if (is_writable ($file)) {   
 echo "File <b>$file</b> Can be written / diedit<br>";  
 } else {   
 echo "File <b>$file</b> NOT writable /  diedit<br>";
}
//
 if (is_readable ($file)) {   
 echo "File <b>$file</b> Can be read<br>";  
 } else {   
 echo "File <b>$file</b> NOT readable<br>"; 
 }
//
 echo "Access last file <b>$file</b> = ". date("d-m-Y  H:i:s.", fileatime($file)). "<br>";
 echo "File <b>$file</b> Created = ". date("d-m-Y H:i:s.",  filectime($file)). "<br>";
 echo "Last modified file <b>$file</b> = ". date("d- m-Y H:i:s.", filemtime($file)). "<br>";
 echo "File size <b>$file</b> = ". filesize($file). "  bytes<br>";
 echo "File type <b>$file</b> = ".filetype($file). "<br>"; 
 } else if (is_dir($file)){
 echo "File <b>$file</b> Is DIRECTORY<br>";  
 } else {
 echo "File <b>$file</b> Not known<br>"; 
 }
?>

Save the php code with the file12.php name in the htdocs folder. Run the program by opening the browser, then type http://localhost/file11.php in the address bar then enter. The result will look like below.
