PHP - Colon Syntax (:)
The colon syntax can be useful when in project views/partials where you are mixing html and php. Below are some examples for quick reference.
If statements
<?php if ($a == 5): ?>
A is equal to 5
<?php elseif ($a == 6): ?>
A is equal to 6
<?php endif; ?>
While Loops
<?php while ($i <= 10): ?>
<tr>
<td><?php print $i; $i++ ?></td>
</tr>
<?php endwhile; ?>
For Loops
The following will create 10 table cells numbered 1 to 10.
<?php for ($i=1; $i<=10; $i++): ?>
<tr>
<td><?= $i; ?></td>
</tr>
<?php endfor; ?>
