Readfiles Script

From Superk

This script is really rough and will read in both regular files as well as directories. Need to do more research on the readdir() function.

#!/usr/bin/php

<?php
// Set the directory to read ('/' for Unix & '\\' for Windows (I think))
$dir = '/home/bkrein';

// If the directory exists, run the loop
if($loc = opendir($dir)) {
    echo "Files: \n\n";
    
    // Loop through the files in the $dir
    // NOTE: '!==' only works on PHP 4+
    while(false !== ($file = readdir($loc))) {
        // If the filename matches the expression, display it
        if((preg_match("/update/", $file))&&(filetype($file) == 'file')) {
            echo "<a href=\"$dir/$file\">$file</a>\n";
        }
    }
    
    // Close the directory (cleanup)
    closedir($loc);
}
?>

Produces this output:

bkrein@bkreinlap:~$ php readfiles.php 

Files: 

<a href="/home/bkrein/update-1.4.3.tgz.gpg">update-1.4.3.tgz.gpg</a>
<a href="/home/bkrein/update-1.4.4.tgz.gpg">update-1.4.4.tgz.gpg</a>
<a href="/home/bkrein/update-1.4.5.tgz.gpg">update-1.4.5.tgz.gpg</a>

The following code is similar to the above, but reads the filename and date into an array then sorts the array based on the timestamp:

#!/usr/bin/php

<?php
// Set the directory to read ('/' for Unix & '\\' for Windows (I think))
$dir = '/home/bkrein';


function cmp($a, $b) {
    return strcmp($a['date'], $b['date']);
}

// If the directory exists, run the loop
if($loc = opendir($dir)) {
    echo "Files: \n\n";
    
    // Loop through the files in the $dir
    // NOTE: '!==' only works on PHP 4+
    while(false !== ($file = readdir($loc))) {
        // If the filename matches the expression, display it
        if((preg_match("/[0-9]{2}/", $file))&&(filetype($file) == 'file')) {
            $files[] = array('file' => $file, 'date' => filemtime($file));
        }
    }
    
    // Close the directory (cleanup)
    closedir($loc);

    usort($files, 'cmp');
        
    foreach($files as $item) {
        echo '<a href="'.$dir.'/'.$item['file'].'">'.$item['file'].'</a> - Last modified on: '.date("F d, Y", strtotime($file['date']))." (Timestamp: ".$item['date'].")\n";
    }
}
?>

This script outputs:

bkrein@bkreinlap:~$ php readfiles.php
