php sql formatting SELECT columns numbers - php

Question

I am retrieving various columns from an SQL table and some of those are numeric or currency, in a sample let’s say:
$sql="SELECT id_column, event_column, amount_column FROM table1";
Then I show them using that:
$result = mysqli_query($conn,$sql);
echo "<table border='1'>
<tr>
<th>id</th>
<th>event time</th>
<th>amount</th>
</tr>";
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row[' id_column '] . "</td>";
echo "<td>" . $row[' event_column '] . "</td>";
echo "<td>" . $row[' amount_column '] . "</td>";
echo "</tr>";
}
echo "</table>";
Is it possible to change the format numbers get out in amount_column?
I saw should be possible to use a command to change a single number data the way I wuold like - number_format($number, 2, ',', '.') – but this seems not to apply for entire columns
What I do need is using comma for decimal under one (yy) and point for others grouped by 3 (x.xxx) thousands, something like xx.xxx.xxx,yy
Does some one have any suggestion? (including how to change the settings in PHP or SQL by the moment when I entry the data via form those have a comma instead of point for decimal but SQL save them in a different way – UK/USA decimal punctuation I guess while I need EU Italian/Germany punctuation or at least the ISO standard using comma for decimal and space for each group of three numbers).

Answer 1

Correct answer is my comment:
echo "<td>" . number_format($row['amount_column'], 2, ',', ' ') . "</td>";
You can not do:
$row[' amount_column ']
Spacing for array index count!

So technically the answer you've approved - is wrong.

UPDATE:
Yes, true money_format works not on windows. Thanks Dave. :)
Use number_format( $row[' amount_column '], 2, ',', '.')
It gives you something like 123.456.789,12
PHP number_format
(Not on windows!)
You can use php´s money_format('%i', $row[' amount_column '])
PHP money_format
<?php
setlocale(LC_MONETARY, 'en_US');
$result = mysqli_query($conn,$sql);
echo "<table border='1'>
<tr>
<th>id</th>
<th>event time</th>
<th>amount</th>
</tr>";
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row[' id_column '] . "</td>";
echo "<td>" . $row[' event_column '] . "</td>";
echo "<td>" . money_format('%i', $row[' amount_column ']) . "</td>";
echo "</tr>";
}
echo "</table>";
