How to display only the selected option for several chosen checkboxes of my displayed csv file column headers

  
  <table border="0" cellspacing="1" cellpadding="1" class="sortable" >

   

  <?php
      #read CSV file
      $uploadfile = $_SESSION['uploadCsv'];
      
      if (($handle = fopen($uploadfile, "r")) !== FALSE) {
        $mycsv = array();
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
        $mycsv[] = $data;
        fclose($handle);


      #Find the length of the transposed row

      $row_length = count($mycsv);
      
      echo "<form method='post' action=''><table><tr>";
      echo "<th><input type='checkbox' onClick='toggle(this)' /> Select/Deselect All<br/>
      </th>";
      echo "<th>Column</th>";
      echo "<th>Filter</th>";


      echo "</tr>";

      #Loop through each row (or each line in the csv) and output all the columns for that row
      foreach($mycsv[0] as $col_num => $col)
      {
          

        echo "<tr>";
          
    
    
          for($x=0; $x<1; $x++)
          {
              
          

          echo "<td><input type='checkbox' name='lang[]'  value='".$mycsv[$x][$col_num]."' ></td>";
          echo "<td align='center'>"  .$mycsv[$x][$col_num]."</td>";
          echo "<td>
            <select name='method[]' >
