php array search key & value by value form other array - php

Question

I have an reference array like this (the data amount is dynamic, about 3000 records)
Array
(
[0] => Array
(
[DEPT] => FIN
[KEYCODE] => AAAAA
[TYPE] => 7
)
[1] => Array
(
[DEPT] => SALE
[KEYCODE] => BBBBB
[TYPE] => 16
)
[2] => Array
(
[DEPT] => SCM
[KEYCODE] => CCCCC
[TYPE] => 1
)
)
and use the value of "TYPE" to search keys "[9][7][16][1]" and value of "KEYCODE" to search value of above keys in following array. (dynamic, about 5000 records)
Array
(
[0] => Array
(
[NAME] => Nick
[9] => GGGGG
[7] => AAAAA
[16] => MMMMM
[1] => KKKKK
)
[1] => Array
(
[NAME] => Chris
[9] => PPPPP
[7] => BBBBB
[16] => ZZZZZ
[1] => RRRRR
)
[2] => Array
(
[NAME] => Cathy
[9] => SSSSS
[7] => UUUUU
[16] => JJJJJ
[1] => AAAAA
)
[3] => Array
(
[NAME] => Allen
[9] => FFFFF
[7] => DDDDD
[16] => WWWWW
[1] => CCCCC
)
)
the output array should be
Array
(
[0] => Array
(
[NAME] => Chris
[9] => PPPPP
[7] => HHHHH
[16] => ZZZZZ
[1] => RRRRR
)
[1] => Array
(
[NAME] => Cathy
[9] => SSSSS
[7] => UUUUU
[16] => JJJJJ
[1] => XXXXX
)
)
"Nick" have item [7]=> AAAAA and "Allen" have item [1]=> CCCCC, so delete from data array.
I know the way to delete array item, but no idea to implement compare and search by key/value pair from other array.

For what I understand from your question, here's a simple solution for your required task:
$firstArr = array(
0 => array(
"DEPT" => 'FIN',
'KEYCODE' => 'AAAAA',
'TYPE' => 7
),
1 => array(
'DEPT' => 'SALE',
'KEYCODE' => 'BBBBB',
'TYPE' => 16
),
2 => array(
'DEPT' => 'SCM',
'KEYCODE' => 'CCCCC',
'TYPE' => 1
)
);
$secondArr = array(
0 => array(
'NAME' => 'Nick',
9 => 'GGGGG',
7 => 'AAAAA',
16 => 'MMMMM',
1 => 'KKKKK',
),
1 => array(
'NAME' => 'Chris',
9 => 'PPPPP',
7 => 'HHHHH',
16 => 'ZZZZZ',
1 => 'RRRRR'
),
2 => array(
'NAME' => 'Cathy',
9 => 'SSSSS',
7 => 'UUUUU',
16 => 'JJJJJ',
1 => 'XXXXX'
),
3 => array(
'NAME' => 'Allen',
9 => 'FFFFF',
7 => 'DDDDD',
16 => 'WWWWW',
1 => 'CCCCC'
)
);
foreach($firstArr as $row){
foreach($secondArr as $i => $que){
if(array_key_exists($row['TYPE'], $que) && $row['KEYCODE'] == $que[$row['TYPE']]){
unset($secondArr[$i]); // deleting selected item from the array...
}
}
}
echo '<pre>';
print_r($secondArr);
echo '</pre>';
Output of the above code:
Array
(
[1] => Array
(
[NAME] => Chris
[9] => PPPPP
[7] => HHHHH
[16] => ZZZZZ
[1] => RRRRR
)
[2] => Array
(
[NAME] => Cathy
[9] => SSSSS
[7] => UUUUU
[16] => JJJJJ
[1] => XXXXX
)
)
