display 5 arrays values per row - php

Question

I am trying to make a calendar:
<table border="1">
<tr><th colspan="7"><?php echo $current_month ?></th></tr>
<tr>
<?php foreach ($days as $day) {
echo "<th>" . $day . "</th>";
} ?>
</tr>
<tr>
<?php
foreach($keys as $row => $value) {
echo "<td>" . $value . "</td>";
}
?>
</tr>
</table>
How can I do to echo 7 values per row? AS you can see in the image, it displays all days in the same row. (of course, because I have put it in the same , but, how can I make that starts a new every 7 echo values?
Thank you!!!

Answer 1

You can use modulus to check if it has reached the seventh element and end the row.
<?php
foreach($keys as $row => $value) {
if ($value % 7 == 0) {
echo "<td>" . $value . "</td></tr><tr>";
} else {
echo "<td>" . $value . "</td>";
}
}
?>

Answer 2

An iteration counter is a pretty simple method.
<table border="1">
<tr><th colspan="7"><?php echo $current_month ?></th></tr>
<tr>
<?php foreach ($days as $day) {
echo "<th>" . $day . "</th>";
} ?>
</tr>
<tr>
<?php
$i = 0; // Begin at 0 days written
foreach($keys as $row => $value) {
if ($i == 7){
// Create new table row after every 7th iteration
print "</tr><tr>"; // Add \n or \t for output formatting
$i = 0;
}
echo "<td>" . $value . "</td>";
$i++; // Increment $i each iteration
}
?>
</tr>
</table>

Try the below code,
You can split the array into chunks of particular sizes, See more information about this from here array chunk
<?php
$current_month = 'Oct';
$days = array('1',2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31);
$chunk = array_chunk($days,7);
?>
<table border="1">
<tr>
<th colspan="7"> <?php
echo $current_month; ?>
</th>
</tr>
<?php
foreach($chunk as $day) {
echo '<tr>';
foreach($day as $key) {
echo "<th>" . $key . "</th>";
}
echo '</tr>';
} ?>
