How to create dynamic table from both directory and CSV files - php

Question

I need to create a table whose first column is populated from subdirectory names inside a directory and rest are from a CSV file. This have to be a dynamic table and table headers have to be added from the code. What's wrong with my code?
I am an absolute beginner. So, please ignore my stupidity.
$dir = 'D:\workspace';
$dirlist = preg_grep('/^([^.])/', scandir($dir));
$row = 1;
if (($handle = fopen("D:\workspace\demo\database.csv", "r")) !== FALSE) {
echo "<table border='1' style='border-collapse: collapse;border-color: silver;'>";
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
$num = count($data);
if ($row == 1) {
echo '<thead><tr>';
}else{
echo '<tr>';
}
for ($c=0; $c < $num; $c++) {
if(empty($data[$c])) {
$value = " ";
}else{
$value = $data[$c];
}
if ($row == 1) {
echo '<th>'.$value.'</th>';
}else{
foreach ($dirlist as $rowdirectory)
{
echo '<td>' . $rowdirectory . '</td>';
echo '<td>'.$value.'</td>';
}
}
}
if ($row == 1) {
echo '</tr></thead><tbody>';
}else{
echo '</tr>';
}
$row++;
}
echo '</tbody></table>';
fclose($handle);
}

<?php
#------------------------------------------Function for Reading Directory-------------------------------------------
function readdirectory($dir)
{
$dirlist = preg_grep('/^([^.])/', scandir($dir)); // for all(./../anything that
starts with .)
//$dirlist = preg_grep('/[^.]/', scandir($dir)); //only . & ..
//$dirlist =preg_grep('/^[(^.)]/', scandir($dir));//only files that starts with .
return $dirlist;
}
#------------------------------------------Function for Reading CSV file-------------------------------------------
function readcsvfile($source)
{
$handle = fopen($source, "r");
$filecontent = null;
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE)
{
$filecontent[] = $data;
}
fclose($handle);
return $filecontent;
}
$filecontent= readcsvfile("D:\workspace\demo\database2.csv");
#-------------------Directory Function calling, header array cration and other declaration------------------------------------
$conf_prefix= "../";
