Question

I am upgrading the way my website runs, I have already integrated mant php scripts in pages, but I am trying to develop fully php based site, eg, instead of loading urls:

url/events/event-1
url/events/event-2

^^^ 2 seperate pages

I am trying to load

url/event?url=event-1

this is so I can update 1 page but load different content depending on the

$_GET['url']

parameter…..

what I have so far…

I load url/event?url=dance

it will automatically search a directory for the filename ‘dance.txt’

if the file does not exist, it forwards to main events page (url/events)

if the files does exist, it creates a one line string about the event….

the file content is listed like this:

Dance::::18-02-2012::::http://{external link}::::Event Information

the script I have developed to import this data and display it, works fine, but I need a page that will load all events each in a separate div…….

producing this page is simple enough if I can figure out how to arrange the event array data into a multidimensional array for all events…

for individual events, the script simply defines variables as:

$name, $date, $link, $writeup

I have attached sample code of how I do this…

    $dir    = '/server/htdocs/data/';     // path to dir with all event txt files in
$files = scandir($dir);

$fruit = array_shift($files);

$fruit2 = array_shift($files);    // array shifts remove values of '.' and '..'

$line = implode(" ",$files);    // back into string for str_replace

// echo $line;

$oldword = ".txt";

$newword = "";

$newline = str_replace($oldword, $newword, $line);

// echo $newline;


$files = explode(" ", $newline); // array of filenames

if (in_array($url, $files)) {
  $contents = file_get_contents('data/'.$url.'.txt');
} else { header('Location: http://{url}/events'); }

$info = explode('::::', $contents);

// print_r($info);

$name = $info[0];

$date = $info[1];

$link = $info[2];

$writeup = $info[3];

this works perfectly for individual pages, however, I need to have an array like this:

$events = array ( array ( Name => event-1,
                          Date => date-1,
                          Link => link-1,
                          Writeup => event-info ),

                  array ( Name => event-2,
                          Date => date-2,
                          Link => link-2,
                          Writeup => event-info ),

                  array ( Name => event-3,
                          Date => date-3,
                          Link => link-3,
                          Writeup => event-info )
                        );

this is how I presume the array would be formed, but I need the script to count how many files there are in the /data/ folder, and then (I’m presuming) have a foreach loop so that for each array (event) I can echo:

<div id="content2"> 
                    <div class="post">
<center><h2><u>'.$name.' ('.$date.')</u></h2></center>
                       <p class="postmeta"></p>
                        <div class="entry">

<CENTER><img src="events/posters/'.$name.'.jpg" height="400" width="500"></center>

<p><p>

<p>'.$writeup.'</p>

<p><a href="'.$link.'" " target="_blank">'.$name.' Online</a></p>


 </div>
                    </div><!-- post --> 
                </div><!-- content2 -->

I know it may seem a complicated way of going around things, but this way my site will be 100% editable via data in txt files, as right now I have to clone existing page, then re-write all content in it for new event!

foreach($files as $key => $value) {

$array[] = array(explode('::::',(file_get_contents('data/'.$files[$key].'.txt'))));

}

print_r($array);

gives me:

aha nearly done.

ps I would like foreach to list by dates stated in each txt file, it currently lists alphabetically from filenames…

Answer 1

Borrowed a bit of Jribeiro’s code to actually read the files into the two-dimensional array.

$items = array();
if ($handle = opendir($dir)) {
    while (false !== ($file = readdir($handle))) {
        $fp = fopen("$file","r");

        while($line = fgets($fp)){
            $parts = explode("::::",$line);
            $newArr["Name"] = $parts[0];
            $newArr["Date"] = $parts[1];
            $newArr["Link"] = $parts[2];
            $newArr["Writeup"] = $parts[3];
            $items[] = $newArr;  // add newArr to items
        }
        fclose($fp);
    }
    closedir($handle);
}

print_r($items);

Then, to loop through the $items array:

foreach($items as $item){
    $name = $item["Name"];
    echo "Name is $name<br>";
    // etc
}

Although, I’m required to inform you to look into using MySQL to do this as it is much easier, safer, and more powerful than using a flat text file.
