PHP, multidimensional arrays: to intersected events with days of the month - php

Question

I want to build a movie timetable. I have $array1 containing the movie titles and airing dates and times:
array =
0: array =
Title: string = American Beauty
Date: string = 25/09/2012
Time: string = 15:00 - 16:20
1: array =
Title: string = The Godfather
Date: string = 25/09/2012
Time: string = 16:20 - 18:20
2: array =
Title: string = Pulp Fiction
Date: string = 26/09/2012
Time: string = 15:00 - 16:20
And I have $array2 containing the days of the month grouped by Mondays, Tuesday s, Wednesday s, Thursday s and Fridays (no movies during the weekend)
Array
(
[1] => Array
(
[0] => 3
[1] => 10
[2] => 17
[3] => 24
[4] =>
)
[2] => Array
(
[0] => 4
[1] => 11
[2] => 18
[3] => 25
[4] =>
)
[3] => Array
(
[0] => 5
[1] => 12
[2] => 19
[3] => 26
[4] =>
)
[4] => Array
(
[0] => 6
[1] => 13
[2] => 20
[3] => 27
[4] =>
)
[5] => Array
(
[0] => 7
[1] => 14
[2] => 21
[3] => 28
[4] =>
)
)
I need to intersect these two arrays so I can print under day 25 the movie “American Beauty” also under day 25 “The Godfather” and under day 26 “Pulp Fiction”.
Meaning I need to print:
SEPTEMBER 2012
Monday Tuesday Wednesday ....
3 4 5
10 11 12
17 18 19
24 25 26
15:00-16:20 American Beauty 15:00-16:20 Pulp Fiction
16:20-18:20 The Godfather
My tries so far:
foreach( $array1 as $key => $value )
{
$theTime = $value['Time'];
$theTime = explode("/", $theTime );
$days[] = $theTime [0];
$months[] = $theTime [1];
}
So I have all the airing days in array $days but from here I don’t know how to follow or even if this approach is the correct one.
Here's how I get $array2:
$month = 9;
$year = 2012;
for ($i = 1; $i <= 31; $i++)
{
$timestamp = mktime(0, 0, 0, $month , $i, $year);
if (date("n", $timestamp) == $month )
{
$day = date("N", $timestamp);
// Monday 1 to Friday 5
if ($day == 1 OR $day <= 5) {
$array2[$day][] = date("j", $timestamp);
}
}
}
Please help, I’m stuck.
Thanks very much

Ok you will iterate over $array1 and parse the date of the movie.
Then, you will look inside array2 if your day is there
foreach($array1 as $movie){
$movieDate = new DateTime($movie);
//as you indexed $array2 with monday = 1 -> friday = 5 you can use the "w" format
if(isset($array2[$movieDate->format("w"))){
$array[$movieDate->format("j")][] = $movie;
}
}
I made some mutation in your output array, it becomes :
SEPTEMBER 2012
Monday Tuesday Wednesday ....
3=>[] 4 =>[] 5=>[]
10=>[] 11 =>[] 12=>[]
17=>[] 18 =>[] 19=>[]
24 =>[] 25=>[ 26 =>[
15:00-16:20 American Beauty, 15:00-16:20 Pulp Fiction]
16:20-18:20 The Godfather]
