How to control order of files being displayed in dynamic select box

I haven't touched PHP in about 11 years so be kind to me! I need to update code that builds a dynamic select on a page. It just reads in the files. How can I control the order of the files displayed? I want a specific file to be first.

function load($htmlFrm, $cancelFormSubmission){
            global $OMNITURE_REPORTS_DIR;
            
            // load the drop down data
            $type = $this->dataRow['type']->getValue();
            $typeFilter = "val not like 'locale%'"; // by default do not show locale types.
            if (preg_match('/locale/', $type)){
                  $typeFilter = "val like 'locale%'";
            }
            $this->typeList = new CSimpleDataSet($this->db, new CQuery(new CString("SELECT caption, val FROM lists WHERE groupName='opsr2.omniture.type' AND $typeFilter ORDER BY priority ASC")));
            $this->typeList->loadData();

            // get the report template file list;
            if (self::$reportList === null){
                  self::$reportList = array();
                  foreach (scandir($OMNITURE_REPORTS_DIR) as $file){
                        // only show files in the reports menu, not directories.
                        if (is_file("$OMNITURE_REPORTS_DIR/$file")){
                              self::$reportList[] = new CString($file);
                        }
                  }
            }
/////////////////////////////////////////////////////////////////////////////////////////
// generate a report list pulldown menu:
                  if (count(self::$reportList)){
                        $reportSel = new CSelect($this->parentReport->getHtmlFrm(), new CString("reportSelector"), new CString(''));
                        $reportSel->setClassName('reportSelector');
                        foreach (self::$reportList as $file){
                              $reportSel->addOption($file,$file);
                        }
                        $tpl->assign('html_reportSelector',$reportSel->getHtml());
                  } // end: if

What are these classes from (maybe part of a larger framework?)  How do you know which file you want to display first?  File name?  Oldest?  Newest?  There are probably some ways to make an array of objects that would allow many different ways to sort the list of files or pick out the one you want first.

I believe that scandir() returns an array of file names.  There is this line in the code:  foreach (scandir($OMNITURE_REPORTS_DIR) as $file){  That would suggest to me that you might look at the file names inside the iterator loop created by foreach() and select the desired file.  Add it to an output array at position zero.  Remove it from the scandir() results.  Then iterate over the scandir() results again, adding the rest of the file names to the output array.

You could also use the dir() class in php.

The page also has an example.
