How to use modulo in PHP tables?
<table border="1">
<?php for ($i = 1; $i <= 20; $i++): ?>
<?php if ($i % 5 == 0): ?>
<tr>
<?php endif ?>
<td><?php echo $i ?></td>
<?php if ($i % 5 == 0): ?>
</tr>
<?php endif ?>
<?php endfor ?>
</table>
This example show me:
1 2 3 4
5
6 7 8 9
10
11 12 13 14
15
16 17 18 19
20
I would like receive:
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
What I must use in if?
let's look at what you are doing: you start a row when $i is a multiple of five and you end a row when $i is a multiple of five. in any other case, you just print the number. so your row can only contain the value 5.
but: you want a row containing 1,2,3,4,5 - so you have to finish the row after 5, what you are doing, but start it before 1.
<table border="1">
<?php for ($i = 1; $i <= 20; $i++): ?>
<?php if ($i % 5 == 1): ?>
<tr>
<?php endif ?>
<td><?php echo $i ?></td>
<?php if ($i % 5 == 0): ?>
</tr>
<?php endif ?>
<?php endfor ?>
