Simple counter for PHP
Why needed
Sometimes you need to display a counter steps in a loop where the index of the loop is consumed by a non-serial number.
$workHoursLog = [
'2016-01-01'=>10,
'2016-01-02'=>10,
'2016-01-03'=>8,
//...
];
As you can see, the key is not a serial number, any you may want to display in a table:
<table>
<?php foreach($workHours as $date=>$hours): ?>
<tr>
<td><?= Counter::nextOrInit($i, 1) ?></td>
<td><?= $date ?></td>
<td><?= $hours ?></td>
</tr>
<?php endforeach; ?>
</table>
result will be
<table>
<tr>
<td>1</td>
<td>2016-01-01</td>
<td>10</td>
</tr>
<tr>
<td>2</td>
<td>2016-01-02</td>
<td>10</td>
</tr>
<tr>
<td>3</td>
<td>2016-01-03</td>
<td>8</td>
</tr>
</table>
How to use
Simply, call the nextOrInit method and pass a unique variable which will hold the counter object, optionally a second parameter which is the start, and a step:
\ItvisionSy\Counter\Counter::nextOrInit($counter,[$start=0,[$step=1]]);
Or you can initiate
//initiate
$counter = new Counter(0,1);
//OR
Counter::nextOrInit($counter, 0, 1);
// get current value
echo $counter;
//OR
echo $counter();
//OR
echo $counter->current();
//next step
$counter->next();
//OR
$counter(true);
