Reading multiple files into the same array

[Echilon]

I have a directory full of text files, I need to read every line, from every file into an array so I can display it using HTML. I'm grabbing the names of the files I need into an array using

          if($dir = @opendir(calpath."includes/data/")) {
             while (($eventsfile = readdir($dir)) !== false) {
                   if(preg_match('/^events\_[0-9]{4}\-[0-9]{2}\.conf$/', $eventsfile)) {
                       $filelist[] = $eventsfile;
                   }
             }
          closedir($dir);
          }

Then I need to open each one and read each line into the next available index of an array. First I tried using

$events .= file('/home/echilon/public_html/db/'.$eventsfile);

But nothing happened. I thought I could try to read each file into a separate array, then merge them all. The main problem is that I don't know how many files there will be in the directory. I'm trying to use this ATM:

             if(is_array($filelist)) {
               $arys = 0;
               foreach($filelist as $evfile) {
                 $eventsi.$$arys = file(calpath.'includes/data/'.$evfile);
                 $arys++;
               }
               for($i=0;$i<$arys;$i++) {
                 if($i == $arys-1) {
                   $mergestring .= '$eventsi'.$i;
                 } else {
                   $mergestring .= '$eventsi'.$i.', ';
                 }
               }
//               echo $mergestring;
               $events = array_merge($mergestring);
               foreach($events as $event) {
                 echo $event.'<br />';
               }
             }

If I echo $mergestring, the names of the arraya I need to merge are shown, but array_merge isn't accepting the string as a paramater, it's just printing the contents of $mergestring ($eventsi0, $eventsi1, $eventsi2, $eventsi3). What should be happening is $event in the last foreach loop should print every line of every text file.

Thanks for any help.

    $file_array = array();
    while (($eventsfile = readdir($dir)) !== false) { 
        if(preg_match('/^events\_[0-9]{4}\-[0-9]{2}\.conf$/', $eventsfile)) { 
            $temp = file($eventsfile); 
        }
        $file_array = array_merge($file_array, $temp); 
    } 
    closedir($dir); 
}
