How to retrieve data from multiple arrays - php

Question

I have two arrays that was converted from csv file.
The first csv line looks like this:
franchise_id,franchise_name,phone,website,email,region_codes;
1,"Abbott, Hackett and O`Conner",1-648-177-9510,auto-service.co/bw-319-x,Lupe-2485#auto-service.co,"36101,36055,36071";
The second csv line looks like this:
postal_code,region_code,city,state,region;
14410,36055,Adams Basin,NY,Monroe;
I converted these lines to arrays like this:
//Region Array
$region_lines = explode(PHP_EOL, $region_mappings_string);
$region_array = array();
foreach ($region_lines as $region_line) {
$region_array[] = str_getcsv($region_line);
}
//Franchise Array
$franchise_lines = explode(PHP_EOL, $franchises_string);
$franchise_array = array();
foreach ($franchise_lines as $franchise_line) {
$franchise_array[] = str_getcsv($franchise_line);
}
After that I got the result like this for Region:
Array
(
[0] => Array
(
[0] => postal_code
[1] => region_code
[2] => city
[3] => state
[4] => region;
)
[111] => Array
(
[0] => 14410
[1] => 36055
[2] => Adams Basin
[3] => NY
[4] => Monroe;
)
[112] => Array
(
[0] => 14617
[1] => 36055
[2] => Rochester
[3] => NY
[4] => Monroe;
)
And for franchise:
Array
(
[0] => Array
(
[0] => franchise_id
[1] => franchise_name
[2] => phone
[3] => website
[4] => email
[5] => region_codes;
)
[1] => Array
(
[0] => 1
[1] => Abbott, Hackett and O`Conner
[2] => 1-648-177-9510
[3] => auto-service.co/bw-319-x
[4] => Lupe-2485#auto-service.co
[5] => 36101,36055,36071;
)
What I need to do is to look for 14410 postal code from the first array, get the region_code and look for this region_code in second array and then output the results in PHP. How can this be done?

Answer 1

Will have to loop over franchises array and run simple comparison
function getDataByRegionCode($code, $franchiseArray) {
foreach ($franchiseArray as $key => $data) {
if(isset($data[5])){
$codes = explode(',',$data[5]);
if(in_array($code,$codes)) return $data;
}
}
return NULL;
}
print_r(getDataByRegionCode(14410,$franchiseArray));
