Hi all
I need to compare values of multiple arrays, the tricky thing: I can't just
use array_diff, because I also need to count all the occurences and give
them back. The more tricky thing: It's a foreach loop through $arr[x
['comparable value'] while x is 1,4,3,6... so it's not that easy to compare
one item in the array under index 4 with the next one(which is in 3)
because foreach just loops.
The idea is: If two keys of different arrays hold the same value, I want to
just show one entry and tell the same time, how often it occurs(in other
arrays), so I don't show all the entries(as I would, if they weren't the
same.
But it is still a bit more complicated, because: only if the date_s value
lies 7 days from each other, I want to "concatenate" them to one entry +
show the number of occurences.
In the example below, the lessons 18 and 15 fit that need.
so I want them to be shown as:
[room] : Raum1
[teacher] : Marianne
[class] : SundayClass
starttime : 1099404000 (which is Array[19][date_s])
endtime : 099418400 + 7*24*60*60 (which is Array[15][date_e])
occurences : 2
eg ---------->
print_r($my_big_array) shows:
Array
(
[7] => Array
(
[name] => course1
[comment] => my bad comment
[lessons] => Array
(
[14] => Array
(
[room] => Raum2
[teacher] => Andrew
[class] => Team2
[date_s] => 1100796900
[date_e] => 1100805000
)
)
)
[3] => Array
(
[name] => test
[comment] => testing
[lessons] => Array
(
[19] => Array
(
[room] => Raum1
[teacher] => Marianne
[class] => SundayClass
[date_s] => 1099404000
[date_e] => 1099418400
)
[15] => Array
(
[room] => Raum1
[teacher] => Marianne
[class] => SundayClass
[date_s] => 1099404000 + 7*24*60*60
[date_e] => 1099418400 + 7*24*60*60
)
[13] => Array
(
[room] => Raum1
[teacher] => Peter
[class] => Team1
[date_s] => 1100798160
[date_e] => 1100803500
)
)
