Display last entered data from CSV file in PHP? [closed]

Answer 1

$fp = fopen("csvfile.csv", "r");
// read all each of the records and assign to $rec;
while ($rec = fgetcsv($fp)){} 
?>
// rec will end up containing the last line
<table>
<tr><td>Name:</td><td><?= $rec[0] ?></td></tr>
<tr><td>Email : </td><td><?= $rec[1] ?></td></tr>
<tr><td>Cell :</td><td> <?= $rec[2] ?></td></tr>
<tr><td>D.O.B :</td><td> <?= $rec[3] ?></td></tr>
</table>

or if you anticipate the file being really long you can avoid having to walk each record by positioning the file pointer twice the maximum record length from the end of the file and then walking the record set.

$filesize = filesize("csvfile.csv");
$maxRecordLength = 2048;
$fp = fopen("csvfile.csv", "r");
// start near the end of the file and read til the end of the line
fseek($fp, max(0, $filesize - ($maxRecordLength *2));
fgets($fp);
// then do same as above
while ($rec = fgetcsv($fp)){}
?>
<table>
<tr><td>Name:</td><td><?= $rec[0] ?></td></tr>
<tr><td>Email : </td><td><?= $rec[1] ?></td></tr>
<tr><td>Cell :</td><td> <?= $rec[2] ?></td></tr>
<tr><td>D.O.B :</td><td> <?= $rec[3] ?></td></tr>
</table>

Seems inefficient to parse every line of the file with fgetcsv() when you only care about the first and last line. As such, I'd use file() and str_getcsv():

$rows = file('data.csv');
$last_row = array_pop($rows);
$data = str_getcsv($last_row);
// loop and output data

Note: You can use the same logic for the headers by parsing $rows[0].
