How to loop through an associative array in PHP? - php

Question

Lets assume I have the following:
$times = array();
for($month = $current_month; $month <= $end_month; $month++) {
$first_minute = mktime(0, 0, 0, $month, 1);
$last_minute = mktime(23, 59, 0, $month, date('t', $first_minute));
$times[$month] = array($first_minute, $last_minute);
}
I now need to loop through all the $months but I am not sure how I can achieve this.
I have tried foreach() but that requires I enter a value for $month. We are assuming the value is not clear.

Answer 1

Do you mean you need to loop through $times?
A simple foreach will do...
foreach ($times as $month => $mins) {
// $month = the month
// $mins[0] = first minute
// $mins[1] = last minute
}

Answer 2

Can try using foreach() like this
foreach($times as $month=>$val){
echo 'Month: ' . $month . ' ';
echo 'First Minute: ' . $val[0] . ' ';
echo 'last Minute: ' . $val[1];
echo '<br />';
}

Answer 3

Perhaps you should use Datetime instead?
$end_month = 12;
$times = [];
$oneMonth = new DateInterval('P1M');
$dt = new Datetime('midnight first day of'); // 2014-12-01T00:00:00+00:00
while($dt->format('m') <= $end_month) {
$firstSecond = $dt->getTimestamp();
$dt->add($oneMonth); // 2015-01-01T00:00:00+00:00
$lastSecond = $dt->getTimestamp() -1;
$times[$dt->format('m')] = [$firstSecond, $lastSecond];
}
foreach ($times as $month => $seconds) {
// ...
}
But you could only work with Datetime object:
while($dt->format('m') <= $end_month) {
$times[] = clone $dt;
$dt->add($oneMonth);
}
foreach ($times as $month) {
echo $month->format('m'), // 12
$month->getTimestamp();
}
