How to unset array associative multidimensional if key not same - php

Question

I have data like this :
[1] => Array
(
[COMPANY_SERVICE_ID] => CS01
[COMPANY_NAME] => HANOMAN SAKTI PRATAMA, PT - JAKARTA
[TARIFF_CURRENCY] => IDR
[SELLING_SERVICE_ID] => SS01
[CONTAINER_TYPE_ID] => DC
[SERVICE_NAME] => CONTAINER TRUCKING SERVICE
[FROM_QTY] => 1
[TO_QTY] => 100
[FROM_NAME] => TANJUNG PRIOK
[FROM_LOCATION_ID] => L096
[TO_NAME] => BALARAJA
[TO_LOCATION_ID] => L002
[RESULT_LOCATION] => Array
(
[L001] => Array
(
[TARIF_20] => 1.500.000,00
[TARIF_40] => 1.750.000,00
[TARIF_45] => 5.500.000,00
[TARIF_4H] => 3.500.000,00
)
[L002] => Array
(
[TARIF_20] => 500.000,00
)
)
)
i wanna unset value of RESULT_LOCATION if value in RESULT_LOCATION different with value of TO_LOCATION_ID.
What should i do?
i try to remove with code like this :
foreach ($hasil_jakarta as $key => $value) {
foreach ($value['RESULT_LOCATION'] as $key1 => $value1) {
if ($value['TO_LOCATION_ID'] != $value['RESULT_LOCATION'][$key1]) {
unset($hasil_jakarta[$key]['RESULT_LOCATION'][$key1]);
}
}
}
but all value of RESULT_LOCATION deleted. Whats wrong with my code?

Answer 1

You don't have to test the value but the key. Then, unset() arrays with different keys.
Here is an example :
<?php
$a = array(
'COMPANY_SERVICE_ID' => 'CS01',
'COMPANY_NAME' => 'HANOMAN SAKTI PRATAMA, PT - JAKARTA',
'TARIFF_CURRENCY' => 'IDR',
'SELLING_SERVICE_ID' => 'SS01',
'CONTAINER_TYPE_ID' => 'DC',
'SERVICE_NAME' => 'CONTAINER TRUCKING SERVICE',
'FROM_QTY' => 1,
'TO_QTY' => 100,
'FROM_NAME' => 'TANJUNG PRIOK',
'FROM_LOCATION_ID' => 'L096',
'TO_NAME' => 'BALARAJA',
'TO_LOCATION_ID' => 'L002',
'RESULT_LOCATION' => array(
'L001' => array(
'TARIF_20' => '1.500.000,00',
'TARIF_40' => '1.750.000,00',
'TARIF_45' => '5.500.000,00',
'TARIF_4H' => '3.500.000,00'
),
'L002' => array(
'TARIF_20' => '500.000,00'
)
)
);
foreach ($a['RESULT_LOCATION'] as $key => $value) {
if ($key != $a['TO_LOCATION_ID']) {
unset($a['RESULT_LOCATION'][$key]);
}
}
The result will be :
php > print_r($a);
Array
(
[COMPANY_SERVICE_ID] => CS01
[COMPANY_NAME] => HANOMAN SAKTI PRATAMA, PT - JAKARTA
[TARIFF_CURRENCY] => IDR
[SELLING_SERVICE_ID] => SS01
[CONTAINER_TYPE_ID] => DC
[SERVICE_NAME] => CONTAINER TRUCKING SERVICE
[FROM_QTY] => 1
[TO_QTY] => 100
[FROM_NAME] => TANJUNG PRIOK
[FROM_LOCATION_ID] => L096
[TO_NAME] => BALARAJA
[TO_LOCATION_ID] => L002
[RESULT_LOCATION] => Array
(
[L002] => Array
(
[TARIF_20] => 500.000,00
)
)
)
Hope it helps.
EDIT
I saw your snippet and adapt the loop for your needs :
foreach ($hasil_jakarta as $h_j_key => $h_j_value) {
foreach ($h_j_value['RESULT_LOCATION'] as $key => $value) {
if ($key != $h_j_value['TO_LOCATION_ID']) {
unset($hasil_jakarta[$h_j_key]['RESULT_LOCATION'][$key]);
}
}
}
Your code was almost good but the unset line was not. In that case, you need to unset a variable from the $hasil_jakarta array.
Good luck !
