need help with code

[sky55]

hello

 

dont know if i'm in the right forum,but i realy need to know what this code do -

 

function file_act_check( $code )
{
   $lines = file( $GLOBALS['file_act'] );
   if ( is_array( $lines ) )
   {
      $code = " " . $code . "=";
      foreach ( $lines as $line )
      {
         if ( strstr( $line, $code ) )
         {
            $pieces = explode( "   ", $line );
            $days = explode( "=", $pieces[3] );
            $date_st = explode( ": ", $pieces[4] );
            $date_end = explode( ": ", $pieces[5] );
            $days = $days[1];
            list($year, $month, $day) = split( '[/.-]', $date_st[1] );
            $date_st = mktime( 0, 0, 0, $month, $day, $year );
            list($year, $month, $day) = split( '[/.-]', $date_end[1] );
            $date_end = mktime( 0, 0, 0, $month, $day, $year );
            return array( "Days" => "{$days}", "Start" => "{$date_st}", "End" => "{$date_end}" );
         }
      }
   }
   return 0;
}

 

can someone please explain in simple English what it do ? i really need to know

 

if this is not the place for this kind of question i apologize.

 

many thanx

Without seeing the context it is being used in its hard to tell, but it seems to be aking a file, and parsing dates out of it from a simple glance

Well I'm not going to read that huge script, but what exactly are you trying to do here? The purpose is kind of unclear, and you never explained what was wrong with the code (or if there was even a problem at all)

 

A little word of advice: Learn PHP before you try to get over your head with a project. It seems like you don't know anything about PHP at all and are using a fairly advanced script. We aren't going to make it work for you since this is a forum of volunteers. You need to be able to help  yourself before you can get help from us.

hello again,

 

i'm less than a beginner with PHP,but i take it as a challenge to understand this code.

 

someone already told me he can help me with this code if i pay him 100USD ,but i like i said its a challenge.

 

i started to read more and more about PHP and now i understand the code more.

 

now i have one simple(i hope) Q -

 

this code -

 

function file_codes_check( $code )
{
   $lines = file( $GLOBALS['file_codes'] );
   if ( is_array( $lines ) )
   {
      foreach ( $lines as $line )
      {
         list($cc, $day) = split( '=', $line );
         if ( strcmp( $cc, $code ) == 0 )
         {
            return trim( $day );
         }
      }
   }
   return 0;
}

 

 

in which format should i put the lines in the file ?

and i fail to understand the "$cc"

 

many thanx
