PHP file programming (1)-two ways to obtain file information

//Open the file
$file_path="text.txt";
if($fp=fopen($file_path,"r")){
 //Take out File information
 $file_info=fstat($fp);
 echo "";</li>
<li> print_r($file_info);</li>
<li> echo "";
 / /Get out individually
 $file_size=$file_info['size'];
 //The file size is calculated in bytes
 echo "The size of the file is:".$file_size;
 echo "File The time of last access: ".date("Y-m-d H:i:s",$file_info['atime']); //atime means [the time when the file was last accessed]
 echo " echo "< br/>The time when the file was last changed:".date("Y-m-d H:i:s",$file_info['ctime']); //ctime means [the file was last modified by the file owner/file group Time】
}else{
 echo "Failed to open file";
}
//Close the file, this is very important
fclose($fp);
?>

Method 2 to get file information

//The second way to get file information by bbs.it-home.org
$file_path="text.txt";
if(!file_exists($file_path )){
 echo "File does not exist";
 exit();
}
echo "".date("Y-m-d H:i:s",fileatime($ file_path));
echo "".date("Y-m-d H:i:s",filemtime($file_path));
echo "".date("Y-m-d H:i:s" ,filectime($file_path));
//echo "".filemtime($file_path);
//echo "".filectime($file_path) ;
?>
