Array
(
    [0] => Array
        (
            [name] => Lorem
            [number] => 11
        )

    [1] => Array
        (
            [name] => ipsum
            [number] => 22
        )

)

Sure, here's a simple, primitive example (code untested):

<?php
$data = csv_to_array('example.csv');

echo "<table>";
foreach ($data as $row) {
    echo "<tr>";
    foreach ($row as $column) {
        echo "<td>$column</td>";
    }
    echo "</tr>";
}
echo "</table>";

Thank you so much. 😊👍

Hi agaín :)

In the csv file there are two columns ,name and numbers, I will like do use the PHP max() Function to get the highest value in an array of the cummum number?

How can i do that?

There's many ways you can achieve that, I'd suggest reading through this tutorial, or picking up a good book on the PHP language. With a little time, it's easy to pick up the basics.

Thanks I do know some basic PHP and i have made this task, justmore simple, without the csv file, but this is a little more advanced for me :)

<style> table { font-family: arial, sans-serif; border-collapse: collapse; width: 100%; }

td, th {
border: 1px solid #dddddd;
text-align: left;
padding: 8px;
}
</style>

"; echo "Det lavest Tempartur er: ". (min($temp_array)). "°

"; echo " "; $Mtemp = array( "78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 81, 76, 73, 68, 72, 73, 75, 65, 74, 63, 67, 65, 64, 68, 73, 75, 79, 73, 45"); $datesOFM = array('01-01-2011, 02-01-2011, 03-01-2011, 04-01-2011, 05-01-2011, 06-01-2011, 07-01-2011, 08-01-2011, 09-01-2011, 10-01-2011,11-01-2011, 12-01-2011, 13-01-2011, 14-01-2011, 15-01-2011,16-01-2011, 17-01-2011, 18-01-2011, 19-01-2011, 20-01-2011, 21-01-2011, 22-01-2011, 23-01-2011, 24-01-2011, 25-01-2011, 26-01-2011, 27-01-2011, 28-01-2011, 29-01-2011, 30-01-2011, 31-01-2011'); echo " "; foreach($Mtemp as $key => $value) { echo "" .

Thanks @rboatright

As of PHP 8.0, you can set the length to 0 (or null, or omit it entirely) for the fgetcsv() function if you don't want to limit the maximum line length.
