Question

I have a csv file with some data inside.
When User type something in the search bar,it will return the relate data but these results are too much, I want to make a pagination.I don't have any idea, google a lot but can't find a way to do. Please help.
$filename = "Database.csv";
$delimiter = ",";
if (!file_exists($filename) || !is_readable($filename))
return false;
if ($delimiter == ',') {
$csv = array_map('str_getcsv', file($filename));
} else {
$lines = file($filename);
$line_num = count($lines);
$dm = [];
$csv = array_map('str_getcsv', $lines, array_pad($dm, $line_num, $delimiter));
}
array_walk($csv, function (&$row) use ($csv) {
$row = array_combine($csv[0], $row);
});
array_shift($csv);
$total_row_of_csv = count($csv);
$total_row = 0;
for ($i = 0; $i < $total_row_of_csv; $i++) {
if (preg_match("/$value/i", $csv[$i]['Catagory'])) {
echo "<tr>";
echo "<td>" . $csv[$i]['Ref'] . "</td>";
echo "<td>" . $csv[$i]['Catagory'] . "</td>";
echo "<td>" . $csv[$i]['JobTitle'] . "</td>";
echo "<td>" . $csv[$i]['Description'] . "</td>";
echo "<td>" . $csv[$i]['Salary'] . "</td>";
echo "<td>" . $csv[$i]['Nature'] . "</td>";
echo "</tr>";
$total_row++;
}
}

GET : index.php?page=2&search=purchasing
clear the page=1 for a new search
This function is done with get method not post, you can do it as the post by doing appropriately
<?php
// you can make this as post as you want
// i have made this as a get param function
$value = !empty($_GET['search']) ? $_GET['search'] : '';
$filename = "Database.csv";
$delimiter = ",";
if (!file_exists($filename) || !is_readable($filename))
