從PHP數組輸出中隱藏列

Question

我有一個從.txt文件中提取數據並將其放入HTML表中的代碼。代碼寫入的方式比我需要的更多的數據。我怎樣才能隱藏輸出中的列？這回9列，我只需要前5

<?php 

function toASCII($str) { 
    return strtr(utf8_decode($str), utf8_decode(
        'ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ'), 'SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy'); 
} 

require_once 'meekrodb.php'; 

DB::$user = 'root'; 
DB::$password = ''; 
DB::$dbName = 'test'; 
$dirArray = array(); 

$dirpath = 'C:\xampp\htdocs\auditscripts\SCRIPTS\\'; 
$SERVERNAME=array(); 

// open this directory 
$myDirectory = scandir($dirpath); 
// get each entry 
foreach ($myDirectory as $value) { 

    if (is_dir($dirpath . $value)) { 
     $myDirectory = scandir($dirpath . $value); 

     if (is_file($dirpath . $value . '\secedit_mergedpolicy.txt')){ 
      $dirArray[] = $dirpath . $value . '\secedit_mergedpolicy.txt'; 

      $servername[]=$value; 
      } 
    } 
} 

// count elements in array 
$indexCount = count($dirArray); 
Print ("$indexCount files<br>\n"); 
// sort 'em 
sort($dirArray); 
// print 'em 
print("<TABLE border=1 cellpadding=5 cellspacing=0 class=whitelinks>\n"); 
print("<TR><TH>Server Name</TH><th>VALUE01</th><th>VALUE02</th><th>VALUE03</th><th>VALUE04</th><th>VALUE05</th></TR>\n"); 
// loop through the array of files and print them all 
for ($index = 0; $index < $indexCount; $index++) { 
    if (substr("$dirArray[$index]", 0, 1) != ".") { // don't list hidden files 
     $data_tisert = array(); 
     print("<TR><TD>$servername[$index]</td>"); 


     $myString = file_get_contents($dirArray[$index]); 



     $l1 = explode('<br />', nl2br($myString)); 



     $st = false; 
     foreach ($l1 as $vx) { 
     if (!strpos($vx,'=')){ 
      $st=false; 
      } 
      if ($st) { 
       $l1_1 = explode('=', $vx); 
       print("<TD>$l1_1[1]</td>"); 
       $data_tisert[] = $l1_1[1]; 
      } 
      /// echo trim(utf8_encode($vx)) == '[Event Audit]' ? 'y' : 'n'; 



      if (utf8_encode(trim($vx)) == utf8_encode('[Event Audit]')) { 

       $st = true; 
      } 

     } 

     DB::insert('event_audit', array(
      'VALUE01' => $data_tisert[0], 
      'VALUE02' => $data_tisert[1], 
      'VALUE03' => $data_tisert[2], 
      'VALUE04' => $data_tisert[3], 
      'VALUE05' => $data_tisert[4], 
     )); 
     print("</TR>\n"); 
    } 
} 
print("</TABLE>\n"); 
?>

，如果你只想要5，只是把一個計數器陣列上：

相反的：

foreach ($l1 as $vx) { 

使用

for ($ii=0; (($ii < 5) && ($ii < count($l1))); $ii++){ 
    $vx = $l1[$ii];
