Open php file in ascending order

Question

I have an update/ folder with PHP files, so:

These are mysql update files, when it is updated soon after the server erases. When the client does not access the Admin the file stays there, when we release another update then adds the file of the previous version and the latest one and so on until it accesses the Admin to run this update.

My problem:

It is not running in ascending order. I need to make it always open from the smallest to the largest, because that is the order of the update.

Code:

<?php 
$path = $_SERVER["DOCUMENT_ROOT"]."/update/"; 
$diretorio = dir($path); $i = 0;
while($i <= 3){
    $arquivo = $diretorio -> read(); 
    $file = explode("_v", $arquivo);
    if ($file[0] == 'updateSQL'){
?>

    <script type="text/javascript">$(function() {$('#myModal').modal('show');})</script>
    <script type="text/javascript">$('#myModal').modal({backdrop: 'static',keyboard: false})</script>

    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
            <h4 class="modal-title" id="myModalLabel">Espere... Não feche até acabar.</h4>
          </div>
          <div class="modal-body">
            <iframe src="../update/<?php echo $arquivo?>" frameborder="0" height="300px" width="100%" onload="resizeIframe(this);"></iframe>
          </div>
        </div>
      </div>
    </div>

<?php 
    }$i++;
} 
$diretorio -> close();
?>

Answer 1

Save file names to an array and use the function natcasesort() to organize them alphabetically.

Teaching example:

$base = __DIR__.DIRECTORY_SEPARATOR;
$dir = dir($base);
while (false !== ($e = $dir->read()))
    if (is_file($base.$e)) 
        $f[] = $e;
natcasesort($f);
print_r($f);

You just have to be careful with file nomenclature.

Example, archive11.txt will appear before arquivo2.txt because the number 1 comes before the number 2. Alphabetic sorting reads as strings, so to avoid this problem, the nomenclature should have zeros to the left if they contain sequential numbers.

The archive11.txt would look like arquivo000011.txt

The arquivo2.txt would look like arquivo000002.txt

The amount of zeros left, you define as your case.

Answer 2

Friend, besides you can do by a TXT file, if you have a base numbering you can do by this method:

Assembling an Array

You would mount an array with the filename manually or with some PHP directory reading function. With the array ready in the code, it will be enough to feed it with the different files and can run through a while(I will make an example in Python just for you to understand the logic):

i = 0
numeroDeArquivos = Array.len()
while i < numeroDeArquivos:
    open(Array[i], "a")

Answer 3

Good Morning, Friend I have an idea for you to do what you want: You can do as follows each time you do the update you annotate in a txt file the name of the file ex: TXT file = updateSQL_v413.php and at the time of the next update you will:

read the txt file deletes the first 11 string = updateSQL_v divide array by "." = Array[0] = 413, Array[1] = .php. take the array[1] position and sum + 1. >> R: 413 + 1 = 414 the result you go and pull the update by replenishing the 11 string first and joining the numbers + . php that would be:

updateSQL_v414.php.

I hope you understand and help.
