Php5 And Substr Problem

[seeder.us]

I'm having a problem with the following code

 

My problem is i want to limit characters from $file, how can limit

 

[HorribleSubs]_YuruYuri_S2_07_[480p].mkv.qt.mp4

 

into

 

[HorribleSubs]_YuruYuri...

 

 

not necessary for this file above but for every single file that is being echo $file

 

 

I've tried to add it by my self but so far i do not understand it fully

 

like this

 

if ($rest = substr("$file", -1);

 

<?php
$count = 0;
if ($handle = opendir('public')) {
while (false !== ($file = readdir($handle))) {
   if ($file != "." && $file != ".."
[color=#000000][color=#0000BB]   if ($rest [/color][color=#007700]= [/color][color=#0000BB]substr[/color][color=#007700]([/color][color=#DD0000]"[/color][/color]$file[color=#000000][color=#DD0000]"[/color][color=#007700], -[/color][color=#0000BB]1[/color][color=#007700]);[/color][/color]


   && substr($file,-strlen(".html")) != ".html" //if you don't want to include .html files, for instance
   && substr($file,-strlen(".jpg")) != ".jpg" //if you don't want to include .js files, for instance
&& substr($file,-strlen(".sh")) != ".sh" //if you don't want to include .js files, for instance
&& substr($file,-strlen(".srt")) != ".srt" //if you don't want to include .js files, for instance
&& substr($file,-strlen(".sub")) != ".sub" //if you don't want to include .js files, for instance
&& substr($file,-strlen("subs")) != "subs" //if you don't want to include .js files, for instance
&& substr($file,-strlen("png")) != "png" //if you don't want to include .js files, for instance
   && $file != ""
   ) {$count++;
    print("

<a href=\"http://$get_domain/play.php?url=http://$get_domain/public/$file\" title=\"$file\"><li>

   }
}
closedir($handle);
}
