Question

This is pretty basic but I can’t seem to get it to work

I have this query

$people = "SELECT name FROM people";
$people = mysql_query($people) or die(mysql_error());
$row_people = mysql_fetch_assoc($people);
$totalRows_people = mysql_num_rows($people);

I can echo the first result of this query with

<?php echo $row_people['name']; ?>

I could also create a loop and echo all the results.

But I really want to echo the results individually based on its index.

I have tried this, but it does not work.

<?php echo $row_people['name'][2]; ?>

Thanks for your help.

You can fetch them by their index using a WHERE clause.

$people = sprintf("SELECT name FROM people WHERE index='%d'", $index);

If you want to query all rows, you could store them into an array while looping over them:

$people = "SELECT name FROM people";
$people = mysql_query($people) or die(mysql_error());
$totalRows_people = mysql_num_rows($people);
$rows_people = array();
while($row_people = mysql_fetch_assoc($people))
{
    $rows_people[] = $row_people;
}

You might want to add the primary key to the returned fields and use it as the array index probably.
