How to repeat months in loop ? - php

Question

I want to insert dynamic months into database like if user select March then I need to insert record for 12 months from March to Feburary. I am getting dynamic months but when I am trying to insert it into database it insert only first 12 months. I need to repeat the loop again from March to February if user click on add more button. This is my code :
$months = array();
$date="august";
$year= '2014';
//$y= (int)$year;
$currentMonth= date('m', strtotime($date));
$currentyear= date('Y', strtotime('+1 year'));
for($x = $currentMonth; $x < $currentMonth+12; $x++)
{
$months[] = date('F Y', mktime(0, 0, $currentyear, $x,1));
}
//print_r($months);
for($i=0; $i<=23 ; $i++)
{
echo $insert= "insert into month(month_name) values('".$months[$i]."')";
}

Answer 1

as your months array only has 12 values, you can't go to value 23 in that array. What you can do is run through the array twice from 0 to 11, like this:
for($j=0; $j<2 ; $j++)
{
for($i=0; $i<12 ; $i++)
{
echo $insert= "insert into month(month_name) values('".$months[$i]."')";
}
}
or as clyde indicated you can use a modulo operator, which doesn't make you waste 2 loops and thus is faster:
for($i=0; $i<24 ; $i++)
{
echo $insert= "insert into month(month_name) values('".$months[$i % 12]."')";
}

Answer 2

Maybe you can use the DateTime object to do this.
$string = '01-08-2013'; //input string from user
$StartDate = new DateTime($string);
$StopDate = new DateTime($string);
$StopDate->modify('+1 year');
while($StartDate < $StopDate) { //loop as long as $StartDate is smaller than $StopDate
echo "inserting " . $StartDate->format('d/m/Y') . ' into database ' . "<br/>";
//execute mysql query;
$StartDate->modify('+1 month');
}

Answer 3

Your question should state why you want this series of months in the database, as nobody normally does so. Normally people put timestamps on transactions/event records into a database and then report on them.
