I want to make all echoed lines green WITHOUT last 8 lines. However, I don't know how to make it. Any help?

 

Preview: http://tourney.adrenalinex.co.uk/rounds/r2.php

 

Code:

<?
function format_time($t) {
   $minutes = floor($t / 60000);
   $seconds = sprintf('%02d',floor(($t / 1000) % 60));
   $ms = sprintf('%03d', $t % 1000);
   return $minutes . ":" . $seconds . "." . $ms;
}
$highscores = file_get_contents('http://highscores.adrenalinex.co.uk/tourney4.php?c=1&r=2');
$lines = explode("\n", $highscores);
$x=0;
echo "<table style=\"text-align: center; font-weight: bold; border: 1px solid #CCC;\" border=\"1\" cellpadding=\"4\" align=\"center\"><tr><td style=\"background: url('wp-content/themes/arras/images/feed-title-white.jpg'); font-weight: bold; color: red; width: 40px;\"> </td><td style=\"background: url('wp-content/themes/arras/images/feed-title-white.jpg'); font-weight: bold; color: red; width: 200px;\">Drivers Name</td><td style=\"background: url('wp-content/themes/arras/images/feed-title-white.jpg'); font-weight: bold; color: red; width: 100px;\">Time</td><td style=\"background: url('wp-content/themes/arras/images/feed-title-white.jpg'); font-weight: bold; color: red; width: 100px;\">Interval to 1st</td><td style=\"background: url('wp-content/themes/arras/images/feed-title-white.jpg'); font-weight: bold; color: red; width: 100px;\">Interval to driver ahead</td></tr>";
foreach ($lines as &$line) {
   if ($x>0) {
      echo "<TR><TD>$x</TD><TD>$names
</TD><TD>";
      echo format_time($times[$x]);
      echo "</TD><TD>";
      if ($x>1) {
         echo "+ " . format_time($times[$x] - $times[1]);
      } else {
         echo "-";
      }
      echo "</TD><TD>";
      if ($x>1) {
              echo "+ " . format_time($times[$x] - $times[$x-1]);
      } else {
              echo "-";
      }
      echo "</TD></TR>";
   }
   $x++;
   list($names, $times[$x]) = sscanf($line, "%s %d");
}
echo "</TABLE>";
?>

Your code is a little difficult to follow. You can just strip off the last 8 lines the loop using array_slice(). There are also more efficient ways to handle the different handling of the first and subsequent records.

 

<?php

function format_time($t)
{
   $minutes = floor($t / 60000);
   $seconds = sprintf('%02d',floor(($t / 1000) % 60));
   $ms = sprintf('%03d', $t % 1000);
   return $minutes . ":" . $seconds . "." . $ms;
}

$highscores = file_get_contents('http://highscores.adrenalinex.co.uk/tourney4.php?c=1&r=2');
$lines = explode("\n", $highscores);
//Strip off the last 8 records
$lines = array_slice($lines, 0, count($lines)-9);

$table_data = '';
foreach ($lines as $idx => $line)
{
    list($name, $time) = sscanf($line, "%s %d");
    $no = $idx + 1;
    $f_time = format_time($time);
    if($no == 1)
    {
        $first_time = $time;
        $int_to_first = '-';
        $int_to_prev  = '-';
    }
    else
    {
        $int_to_first = format_time($time - $first_time);
        $int_to_prev  = format_time($time - $last_time);
    }

    $table_data .= "<tr><td>$no</td><td>$name</td><td>$f_time</td><td>$int_to_first</td><td>$int_to_prev</td></tr>\n";
    $last_time = $time;
}

?>
<html>
<head>
<style>

.results_table {
    text-align: center;
    font-weight: bold;
    border: 1px solid #CCC;
}

th {
    background: url('wp-content/themes/arras/images/feed-title-white.jpg');
    font-weight: bold;
    color: red;
}
</style>
</head>

<body>
<table class="results_table" border="1" cellpadding="4" align="center">
    <tr>
    <th style="width: 40px;"></th>
    <th style="width: 200px;">Drivers Name</th>
    <th style="width: 100px;">Time</th>
    <th style="width: 100px;">Interval to 1st</th>
    <th style="width: 100px;">Interval to driver ahead</th>
    </tr>
    <?php echo $table_data; ?>
</table>
</body>

You could use jcbones's solution of creating the two or, just create a ternary operator int he code to switch from red to green in the loop. I would do this:

 

<?php

function format_time($t)
{
   $minutes = floor($t / 60000);
   $seconds = sprintf('%02d',floor(($t / 1000) % 60));
   $ms = sprintf('%03d', $t % 1000);
   return $minutes . ":" . $seconds . "." . $ms;
}

$highscores = file_get_contents('http://highscores.adrenalinex.co.uk/tourney4.php?c=1&r=2');
$lines = explode("\n", $highscores);
//Get index of where red records should start
$red_idx = count($lines) - 8;

$table_data = '';
foreach ($lines as $idx => $line)
{
    list($name, $time) = sscanf($line, "%s %d");
    $no = $idx + 1;
    $f_time = format_time($time);
    if($no == 1)
    {
        $first_time = $time;
        $int_to_first = '-';
        $int_to_prev  = '-';
    }
    else
    {
        $int_to_first = format_time($time - $first_time);
        $int_to_prev  = format_time($time - $last_time);
    }

    $class = ($idx<$red_idx) ? 'green' : 'red';
    $table_data .= "<tr class='$class'><td>$no</td><td>$name</td><td>$f_time</td><td>$int_to_first</td><td>$int_to_prev</td></tr>\n";
    $last_time = $time;
}

?>
<html>
<head>
<style>

.results_table {
    text-align: center;
    font-weight: bold;
    border: 1px solid #CCC;
}

th {
    background: url('wp-content/themes/arras/images/feed-title-white.jpg');
    font-weight: bold;
    color: red;
}

.green td { color: green; }
.red td { color: red; }
</style>
</head>

<body>
<table class="results_table" border="1" cellpadding="4" align="center">
    <tr>
    <th style="width: 40px;"></th>
    <th style="width: 200px;">Drivers Name</th>
    <th style="width: 100px;">Time</th>
    <th style="width: 100px;">Interval to 1st</th>
    <th style="width: 100px;">Interval to driver ahead</th>
    </tr>
    <?php echo $table_data; ?>
</table>
</body>
</html>
