Create/fill form with values from uploaded CSV - php

Question

I've decided that to accomplish my task, I need to take the CSV file that is uploaded on my first page, and build a form from it filling the inputs with the CSV values.
I have a functioning CSV upload, but this is to view the CSV and make edits to the fields before saving. I have a while loop that I think I should build the form inside. The only trick is that I've built a CSV data array that handles it upon upload and it's 229 elements long. I need to build the form names to mirror it, so I"ll essentilally be naming 229 form fields, which is fine. Here is the current code that successfully loads the CSV into a table when the button is clicked:
$file = $_FILES["file"]["tmp_name"];
$handle = fopen($file, "r");
$maxPreviewRows = PHP_INT_MAX; // this will be ~2 billion on 32-bit system, or ~9 quintillion on 64-bit system
$hasHeaderRow = true;
echo '<table>';
/*WE WILL NEED TO QA CONDITIONS AND HIGHLIGHT IN RED HERE. ALSO NEED BORDER STYLINGS*/
if ($hasHeaderRow) {
$headerRow = fgetcsv($handle);
echo '<thead><tr>';
foreach($headerRow as $value) {
echo "<th>$value</th>";
}
echo '</tr></thead>';
}
echo '<tbody>';
$rowCount = 0;
while ($row = fgetcsv($handle)) {
echo '<tr>';
foreach($row as $value) {
echo "<td>$value</td>";
}
echo '</tr>';
if (++$rowCount > $maxPreviewRows) {
break;
}
}
echo '</tbody></table>';
}
So, that successfully shows the entire CSV (6 rows, 229 columns per row) for a preview. Now I just need to make each field editable and then insert the entire form upon submit. I know how to insert a form to a database, so now I just need an idea of how to build the form within the while loop and create the names for each input, as well as how to fill the inputs with the actual CSV data.

This is how you can create a form. Each form element is named like row1col1, row1col2, ro1col3 etc...
$file = $_FILES["file"]["tmp_name"];
$handle = fopen($file, "r");
$maxPreviewRows = PHP_INT_MAX; // this will be ~2 billion on 32-bit system, or ~9 quintillion on 64-bit system
$hasHeaderRow = true;
echo '<form>\n';
echo '<table>';
/*WE WILL NEED TO QA CONDITIONS AND HIGHLIGHT IN RED HERE. ALSO NEED BORDER STYLINGS*/
if ($hasHeaderRow) {
$headerRow = fgetcsv($handle);
echo '<thead><tr>';
foreach($headerRow as $value) {
echo "<th>$value</th>";
}
echo '</tr></thead>';
}
echo '<tbody>';
$rowCount = 0;
while ($row = fgetcsv($handle)) {
$colCount = 0;
echo '<tr>';
foreach($row as $value) {
echo "<td><input name='row".$rowCount."col".$colCount."' type='text' value='$value' /></td>";
$colCount++;
}
echo '</tr>';
if (++$rowCount > $maxPreviewRows) {
break;
}
}
echo '</tbody></table>';
echo '<input type=\'submit\' value=\'Submit\' >';
echo '</form>';
