echoing the date modified on top of the files - php

Question

can I echo the date or date modified? on top of every csv file? I had an idea on how to do that but that didn't work out.
<?php
$arrFiles = glob("../Csv_folder/*.csv");
$arrSortedFiles = array();
foreach($arrFiles as $strFileName) {
$arrSortedFiles[$strFileName] = filemtime($strFileName);
}
arsort($arrSortedFiles);
foreach(array_keys($arrSortedFiles) as $strFileName)
{
$file_handle = fopen($strFileName, "r");
while (!feof($file_handle) ) {
$line_of_text = fgetcsv($file_handle, 1024);
echo '<tr><td>' . $line_of_text[0] . '</td><td>' . $line_of_text[1] . '</td><td>' . $line_of_text[2] . '</td><td>' . $line_of_text[3] . '</td><td>' . $line_of_text[4] . '</td></tr>';
}
fclose($file_handle);
}
?>

Answer 1

Use filemtime
Returns the time the file was last modified, or FALSE on failure. The time is returned as a Unix timestamp, which is suitable for the date() function.
Just before you start echoing out your file, you can do
echo "Time: " . date ("F d Y H:i:s.", filemtime($strFileName));
And add a line break or a table row etc. as required.
Edit
Replace your echo with this one
echo '<tr><td>' . $line_of_text[0] . '</td><td>' . $line_of_text[1] . '</td><td>' . $line_of_text[2] . '</td><td>' . $line_of_text[3] . '</td><td>' . $line_of_text[4] . '</td><td>Time: '.date ("F d Y H:i:s.", filemtime($strFileName)).'</td></tr>';
Edit 2
Replace your loop with this
foreach(array_keys($arrSortedFiles) as $strFileName)
{
$file_handle = fopen($strFileName, "r");
echo "<tr><td colspan='5'></td><td>".date ("F d Y H:i:s.", filemtime($strFileName))."</td></tr>";
while (!feof($file_handle) ) {
$line_of_text = fgetcsv($file_handle, 1024);
echo '<tr><td>' . $line_of_text[0] . '</td><td>' . $line_of_text[1] . '</td><td>' . $line_of_text[2] . '</td><td>' . $line_of_text[3] . '</td><td>' . $line_of_text[4] . '</td></tr>';
}
fclose($file_handle);
}
