Modifying Preg_find

[kudzugazette]

Okay, so trying to sort dirdisplay didn't work, so I decided to use preg_find instead. Everything is perfect except for the fact that the results display like this:

1) 2008-08-03 Resources/Students/Report all other problems
2) 2008-08-03 Resources/Students/PRS Clicker Instructions
3) 2008-08-03 Resources/Students/Copyright Violation Policy

When I want them to display like this:
1) 2008-08-03 Report all other problems
2) 2008-08-03 PRS Clicker Instructions
3) 2008-08-03 Copyright Violation Policy

Here is the preg_find code:
<?php
/*

* Paul Gregg <pgregg@pgregg.com>
* 20 March 2004, Updated 20 April 2004
* Updated 18 April 2007 to add the ability to sort the result set
* Updated 9 June 2007 to prevent multiple calls to sort during recursion
* Version: 2.2
* This function is backwards capatible with any code written for a
* previous version of preg_find()
*
* Open Source Code: If you use this code on your site for public
* access (i.e. on the Internet) then you must attribute the author and
* source web site: http://www.pgregg.com/projects/php/preg_find/preg_find.phps

// sorting on values stored in the constructed associative array
// PREG_FIND_SORTBASENAME - Sort the results in alphabetical order on filename
// PREG_FIND_SORTMODIFIED - Sort the results in last modified timestamp order
// PREG_FIND_SORTFILESIZE - Sort the results based on filesize
// PREG_FILE_SORTDISKUSAGE - Sort based on the amount of disk space taken
// to use more than one simply seperate them with a | character

And here is the code on the page:

$students = preg_find('/./', 'Resources/Students',

$facandstaff = preg_find('/./', 'Resources/FacandStaff',
PREG_FIND_RECURSIVE|PREG_FIND_RETURNASSOC|PREG_FIND_SORTMODIFIED|PREG_FIND_SORTDESC);
$i=1;?>

<div id="r_students">
<h2>Resources for students</h2>
<?php foreach($students as $file => $stats) {
printf('<br>%d) %s <a href="show.php?page=%s">%s</a>', $i,
date('Y-m-d', $stats['stat']['mtime']), $file, $file);
$i++;
if ($i > 10) break;
}?>
</div>
<div id="r_staff">
<h2>Resources for Faculty and Staff</h2>
<?php foreach($facandstaff as $file => $stats) {
printf('<br>%d) %s <a href="show.php?page=%s">{$file}</a>', $i,

Thanks much for your help

What are you trying to do? You have found some one else's huge pice of code, just to display the contents of a single directory?

You should look in to glob.

With your result, you can use substr() to cut of the file path.

Here is an example using glob and substr.


Have I not already answered and seen about 3 more questions/threads relating to this exact question?

<?php


// DIRECTORY DISPLAY USING GLOB AND A CLEAN PATH OUTPUT.
// IF ALL PERIMATORS ARE EMPTY WILL SCNA DEFAULT DIRECTORY
// '$path' => PATH TO DIRECOTRY TO SCAN
// '$ext' => FILES EXT, IF YOU WANT OT ECLUDE IT, OR ONLY SCAN FOR ONE TYPE OF FILE
// '$start' => APPEND TO START OF OUTPUT LINE EG: '<li>' OR '<div class="list">'
// '$end' => APPEND TO END OF OUTPUT LINE EG: '</li>' OR '</div>\n' => DEFAULT '\n'
function direcotryList($path = "./", $ext = NULL, $start = NULL, $end = "\n"){
$output = "";
$ignore = array(".","..","thumbs.db");
foreach(glob($path ."*". $ext) as $file){
if(is_file($file) and !in_array($file, $ignore)){
$output .= $start . buildLink($file, $path, $ext) . $end . $nl;
}
}
}

// THIS FUNCTION WILL OUTPUT A CLEAN LINK.
// BUILT FROM THE PREVIOUS FUNCTION.
function buildLink($file, $path, $ext = NULL){
$len1 = strlen($path);
$len2 = strlen($file);
$start = ($len1 - $len2);
$ext = ($start + strlen($ext));
$file = substr($link, $start, -$ext);
$name = str_replace(array("_","-"), array(" "," "), $file);
$link = "<a href=\"{$file}\">". ucwords($name) ."</a>";
return $link;
}

// EXAMPLES OF USE
// OUTPUT SIMPLE LINKS OF ALL FILES IN THE CURRENT DIRECTORY.
echo(direcotryList());

// OUTPUT ALL JPG IMAGES IN DIVS
$output = "<div id=\"gallery\">\n";
$output .= direcotryList("images/",".jpg","<div class=\"image\">","</div>\n");
$output .= "</div>\n\n";
echo($output);

?>

I am using preg_find to display the 10 most recently modified files in the directory.

[Sheldon]

Ok, This should display the XX number of results in X directory sorted by X ( ASC or DESC ).


<?php



// DIRECTORY DISPLAY USING GLOB AND A CLEAN PATH OUTPUT.
// IF ALL PERIMATORS ARE EMPTY WILL SCNA DEFAULT DIRECTORY
// '$display' => AMOUNT OF RECORDS TO DISPLAY
// '$sort' => DISPLAY ORDER 'SORT_DESC' >< 'SORT_ASC'
// '$path' => PATH TO DIRECOTRY TO SCAN
// '$ext' => FILES EXT, IF YOU WANT OT ECLUDE IT, OR ONLY SCAN FOR ONE TYPE OF FILE
// '$start' => APPEND TO START OF OUTPUT LINE EG: '<li>' OR '<div class="list">'
// '$end' => APPEND TO END OF OUTPUT LINE EG: '</li>' OR '</div>\n' => DEFAULT '\n'
function direcotryList($display = 10, $sort = "SORT_DESC", $path = "./", $ext = NULL, $start = NULL, $end = "\n"){
$return = (int)0;
$output = "";
$ignore = array(".","..","thumbs.db");
if(($count = count($files = glob($path ."*.jpg"))) > 0){
foreach($files as $v){
$filemtime[] = filectime($v);
}
array_multisort($filemtime, $sort, $files);
foreach($files as $file){
if($return <= $display){
if(is_file($file) and !in_array($file, $ignore)){
$output .= $start . buildLink($file, $path, $ext) . $end;
$return++;
}
}else{
break;
}
}
}
return $output;
}

?>

EDIT: There is an error on this line:

if(($count = count($files = glob($path ."*.jpg"))) > 0)
Remove the .jpg surrounding the *

if(($count = count($files = glob($path ."*"))) > 0)

Also array_multisort wont allow a variable to sort by.
Remove the $sort variable from the following line and the function definition, then add it directly in to the code.

array_multisort($filemtime, SORT_DESC, $files);

Too late to edit my previous post.
