 PHP Descriptive File Archiver:
This isn't too big of a script, but we'll say it so you can understand it. This tutorial will go through how to list files in a directory, then filter the types of files by extension. Then determining the size of the files in (B,KB,MB). And finally, opening and displaying a file which contains the description of the file which name is the files name but with a ".DSC" extension.
Listing The Files & Sizes:
This is the piece of the script where we get the names of the files from a determined directory and then determine the sizes of the files and create an output variable.
$seldir = getcwd();
$filesat = "qbg"; //qbg is the determined directory
$filels=opendir($filesat);
$r=0;
while (false !== ($file = readdir($filels))) { //repeat until there are no more files in the directory
$r = $r + 1; //Determining the files size in (B,KB,MB) and so on.
if ($r > 2){
$kb = 1024;
$mb = 1024 * $kb;
$gb = 1024 * $mb;
$tb = 1024 * $gb;
$xfile = "qbg/". $file;
$size = filesize($xfile);
if($size < $kb) { //Creating the output variable of the file & it's size
$esta = $size." B";
}
else if($size < $mb) {
$esta = round($size/$kb,2)." KB";
}
else if($size < $gb) {
$esta = round($size/$mb,2)." MB";
}
else if($size < $tb) {
$esta = round($size/$gb,2)." GB";
}
else {
$esta = round($size/$tb,2)." TB";
}
Filtering The Files and determining the description files:
list ($File_name, $Exten) = split('\.', $file);
if ($Exten == "bas"){
$Desc = "qbg/".$File_name.".dsc";
if (file_exists($Desc)) {
$uno = "x";
$rol = $rol +1;
} else {
$Desco = "No Description"; //If Description File Doesn't Exist
$uno="y";
$rol = $rol +1;
}
