List files in a directory

[zzz]

I have a directory with PDF files. I need to be able display a list of the files in that directory and link their names to the actual files. The files keep changing so i need to have a script doing it, rather then adding links manually... 😉

The files are associated with a particular month which is reflected in their names:

filename_1105.pdf -- would be for Nov 2005

Is it possible while printing out a list of the files, have the name of the month spelled out, something like:

<a href="filename_1105.pdf">Filename November 2005</a><br>
<a href="filename_1205.pdf">Filename december 2005</a><br>

I suppose I need to run some sort of loop, but have never done anything similar.

you would need to put this script in a file and have the page reload every so often to update the files

<?php
$dirHandle=opendir('/home/YOUR_FULL_PATH_TO_THE_DIRECTORY_/');
while ($file = readdir($dirHandle)) {
if ($file != "." and $file != "..") { //this checks to make sure that it reads only folders.

$filelength=strlen($file);
$datelength=$filelength - 8; //this is set to read the 8th character from the end
$filenamelength = $filelength - 10; //this sets the max characters to read for the filename

$month1 = $str{$datelength};
$month2 = $str{$datelength + 1};
$year1 = $str{$datelength + 2};
$year2 = $str{$datelength + 3};

if($month1 == '0' and $month2 == '1'){ $month = "January"; }
if($month1 == '0' and $month2 == '2'){ $month = "February"; }
if($month1 == '0' and $month2 == '3'){ $month = "March"; }
if($month1 == '0' and $month2 == '4'){ $month = "April"; }
if($month1 == '0' and $month2 == '5'){ $month = "May"; }
if($month1 == '0' and $month2 == '6'){ $month = "June"; }
if($month1 == '0' and $month2 == '7'){ $month = "July"; }
if($month1 == '0' and $month2 == '8'){ $month = "August"; }
if($month1 == '0' and $month2 == '9'){ $month = "September"; }
if($month1 == '1' and $month2 == '0'){ $month = "October"; }
if($month1 == '1' and $month2 == '1'){ $month = "November"; }
if($month1 == '1' and $month2 == '2'){ $month = "December"; }

echo "<a href='". $file ."'>". $file ." ". $month ." ". $year1 . $year2 ."</a><br>","\n";

}
}
closedir($dirHandle);
?>

if you want the file name to only show what the file is, you will have to figure that one out. i am not sure how to only read a certain length of a variable. I hope this helps.

I did not test the script, i just wrote it. If it does not work, i appologize.

Enjoy!

here is a link to a good resource for string functions.....

Yes, it is possible, but you probably expect a more descriptive answer 🙂

To point you in the right direction (the direction of php manual):
[man]opendir[/man] - see example there on how to read the content of a directory (you've got a nice while loop there).
[man]explode[/man] - if your filenames are similar to name_1105 pdf you can split the string by "_" and you'll have the name.
[man]ucfirst[/man] - to make first letter of the filename uppercase
[man]substr[/man] - to cut out number from your string (1105.pdf)
[man]strtotime[/man] - to convert numbers in the string to timestamp
[man]date[/man] - to convert timestamp to date again (with Nov, November or whatever).
That's all, I think, you'll need for this.

It worked partially, but worked great!

What it does is print the list of the files as links but puts full file name as a link like:

<a href="filename_1105.pdf">filename_1105.pdf</a>

[atokatim]

does it post the month and the year?

[zzz]

No, just prints the name of the files as links to those files.

I got the string in the following format: 1105
How do I get it to spell Novemver 2005?

I've tried the following:

$mo = 1105;
$mo = strtotime($mo);
$mo = date(m y);

But I guess I'm doing something wrong...

[zzz]

OK, with a minor rework, here's what the working version looks like:

$dirHandle=opendir('/home/YOUR_FULL_PATH_TO_THE_DIRECTORY_/');
while ($file = readdir($dirHandle)) { 
	if ($file != "." and $file != "..") { //this checks to make sure that it reads only folders.

	$month1 = substr("". $file ."", -8, 1);
	$month2 = substr("". $file ."", -7, 1);
	$year  = substr("". $file ."", -6, 2);

	if($month1 == '0' and $month2 == '1'){ $month = "January"; }
	if($month1 == '0' and $month2 == '2'){ $month = "February"; }
	if($month1 == '0' and $month2 == '3'){ $month = "March"; }
	if($month1 == '0' and $month2 == '4'){ $month = "April"; }
	if($month1 == '0' and $month2 == '5'){ $month = "May"; }
	if($month1 == '0' and $month2 == '6'){ $month = "June"; }
	if($month1 == '0' and $month2 == '7'){ $month = "July"; }
	if($month1 == '0' and $month2 == '8'){ $month = "August"; }
	if($month1 == '0' and $month2 == '9'){ $month = "September"; }
	if($month1 == '1' and $month2 == '0'){ $month = "October"; }
	if($month1 == '1' and $month2 == '1'){ $month = "November"; }
	if($month1 == '1' and $month2 == '2'){ $month = "December"; }

	echo "<a href='". $file ."'>". $month ." 20". $year ."</a><br>","\n";
}
} 
closedir($dirHandle);

This code works with strtotime and date:

<?php
$str="1105";
$mo = "20".substr($str,2,2)."-".substr($str,0,2)."-01";
$mo = strtotime($mo);
$mo = date("F Y",$mo);
echo $mo;
?>

Here's one that avoids date/time functions (but doesn't validate $str).

$months = array('', 'January', 'February', 'March', 'April', 'May', 'June',
'July', 'August', 'September', 'October', 'November', 'December');

$str = '1105';
list($mo,$yr)=sscanf($str, '%2d%2s');
$display_month = '20'.$yr.' '.$months[$mo];

Yes, a good one. I like compact code. I'll give it a try.

I've got this script to work:

$dirHandle=opendir('/home/YOUR_FULL_PATH_TO_THE_DIRECTORY_/'); 
while ($file = readdir($dirHandle)) { 
    if ($file != "." and $file != "..") { //this checks to make sure that it reads only folders. 

    $month1 = substr("". $file ."", -8, 1); 
    $month2 = substr("". $file ."", -7, 1); 
    $year  = substr("". $file ."", -6, 2); 

    if($month1 == '0' and $month2 == '1'){ $month = "January"; } 
    if($month1 == '0' and $month2 == '2'){ $month = "February"; } 
    if($month1 == '0' and $month2 == '3'){ $month = "March"; } 
    if($month1 == '0' and $month2 == '4'){ $month = "April"; } 
    if($month1 == '0' and $month2 == '5'){ $month = "May"; } 
    if($month1 == '0' and $month2 == '6'){ $month = "June"; } 
    if($month1 == '0' and $month2 == '7'){ $month = "July"; } 
    if($month1 == '0' and $month2 == '8'){ $month = "August"; } 
    if($month1 == '0' and $month2 == '9'){ $month = "September"; } 
    if($month1 == '1' and $month2 == '0'){ $month = "October"; } 
    if($month1 == '1' and $month2 == '1'){ $month = "November"; } 
    if($month1 == '1' and $month2 == '2'){ $month = "December"; } 

    echo "<a href='". $file ."'>". $month ." 20". $year ."</a><br>","\n"; 
} 
} 
closedir($dirHandle); 

It prints all files in my directory like this:

February 2005
February 2005
January 2005
November 2004
December 2004
March 2005
April 2005
May 2005
June 2005
July 2005
August 2005
September 2005
October 2005
November 2005
December 2005
December 20df
January 2006

I'd like to be able to sort by year and then by month starting with the latest going down...

Any suggestions?
