Change date from database into an array - php

Question

I am wondering how to the change date from this
Db -> holiday -> holidayDate (type date) = 2015-01-01, 2015-01-03, 2015-02-19, 2015-03-21, 2015-04-03, 2015-05-01, 2015-05-14, 2015-05-16, 2015-06-02, 2015-07-17, 2015-07-18, 2015-08-17, 2015-09-24, 2015-10-14, 2015-12-25
Here is the code
$sql = "select * from holiday order by holidayDate ";
//echo $sql;
$ambil_data = mysql_query($sql);
if ($data = mysql_fetch_array($ambil_data))
{
$tglLibur2 = $data['holidayDate'];
}
else
{
echo mysql_error();
}
function selisihHari($tglAwal, $tglAkhir)
{
$tglLibur = array("'".$tglLibur2."'"); <= i just want to get this array from db
$pecah1 = explode("-", $tglAwal);
$date1 = $pecah1[2];
$month1 = $pecah1[1];
$year1 = $pecah1[0];
$pecah2 = explode("-", $tglAkhir);
$date2 = $pecah2[2];
$month2 = $pecah2[1];
$year2 = $pecah2[0];
$jd1 = GregorianToJD($month1, $date1, $year1);
$jd2 = GregorianToJD($month2, $date2, $year2);
$selisih = ($jd2 - $jd1);
$libur1 = 0;
$libur2 = 0;
$libur3 = 0;
for($i=1; $i<=$selisih; $i++)
{
$tanggal = mktime(0, 0, 0, $month1, $date1+$i, $year1);
$tglstr = date("Y-m-d", $tanggal);
if (in_array($tglstr, $tglLibur))
{
$libur1++;
}
if ((date("N", $tanggal) == 7))
{
$libur2++;
}
if ((date("N", $tanggal) == 6))
{
$libur3++;
}
}
return $selisih-$libur1-$libur2-$libur3;
}
into this
$tglLibur = array("2015-01-01","2015-01-03","2015-02-19",
"2015-03-21","2015-04-03","2015-05-01","2015-05-14","2015-05-16",
"2015-06-02","2015-07-17","2015-07-18","2015-08-17","2015-09-24",
"2015-10-14","2015-12-25");

Answer 1

First of all your function selisihHari doesn't have access to the variable tglLibur2 you're using inside it. So I'm thinking you didn't post your full code here. But what you're looking for can be done with the following code:
$tglLibur = array()
foreach($tglLibur2 as $date){
$tglLibur[] = $date;
}
But what you're doing in your fetch code doesn't make sense. You keep overwriting the same variable. To change that do the following:
$tglLibur2 = array();
if ($data = mysql_fetch_array($ambil_data))
{
$tglLibur2[] = $data['holidayDate'];
}
This should give you the array you're looking for. That way you can get rid of your function all together.

Answer 2

Assuming that you aren't looping through each row and that $data['holidayDate'] is a string of dates, comma delimited, just change:
$tglLibur2 = $data['holidayDate'];
to
$tglLibur[] = explode(', ', $data['holidayDate']);
