Edit script to display contents of an ftp directory

[biwerw]

I have used this script in the past and it has worked on a local server. How would I set the below script to connect to and display files from a separate ftp?

 

<?php

				// TASK: display a directory listing with thumbnails for images and human-readable filesizes
				// handy humansize function:
				// input is number of bytes, output is a "human-readable" filesize string
				function humansize($size) {

        			// Setup some common file size measurements.
    				$kb = 1024;         // Kilobyte
    				$mb = 1024 * $kb;   // Megabyte
    				$gb = 1024 * $mb;   // Gigabyte
    				$tb = 1024 * $gb;   // Terabyte

        				if($size < $kb) return $size."B";
    				else if($size < $mb) return round($size/$kb,0)."KB";
    				else if($size < $gb) return round($size/$mb,0)."MB";
    				else if($size < $tb) return round($size/$gb,0)."GB";
    				else return round($size/$tb,2)."TB";
				}

				// get local directory path
				$path = "lgl-down";
				?>

				<!--<br />
                    <h3>Files in <?php print $path; ?>:</h3>-->
                    <br />
				<ul class="file-list">
				<?php
				$d = dir($path);
				$icon = '';

				while (false !== ($entry = $d->read())) {

					if ( substr($entry, 0, 1)=='.' ) continue;

					// get size
					$size = filesize($path.'/'.$entry);
					$humansize = humansize($size);

					// find filename extension
					$dotpos = strrpos($entry, '.');

					if ($dotpos) {
						$ext = substr($entry, $dotpos+1);
						if ($ext === 'jpeg' || $ext === 'jpg' || $ext === 'gif' || $ext === 'png' || $ext === 'pdf' || $ext === 'psd' || $ext === 'ai') {
							$icon = "<img src='$path/$entry' style='width:48px; height:auto; vertical-align:text-top; margin:0 4px 8px 0;' alt='' title='$entry' />";
						}
					}
					print "<li>$icon <a href='$path/$entry'>$entry</a> <span class='file-size'>($humansize)</span></li>\n";
					$icon= '';
				}
				$d->close();
				?>

You will have to use PHP's FTP functions: http://us3.php.net/manual/en/ftp.examples-basic.php

If the files are on the same server as where you're running the script you do not need to use the FTP functions of PHP. You just have to set the correct path which is where it goes wrong I suspect?

The files need to be on an ftp.

Below is an updated script I have been working with but receive the following error after hanging for about a minute.

BTW, this is line 49

$contents = ftp_nlist($conn_id, "/download-general"); // replace dot with your dir
