need a simple programming logic solution.. - php

Question

I am working on a CakePHP 2.x but right now my question has nothing to do with the syntax. I need a solution for this problem:
I have a table named messages in which there is a field name mobile numbers. The numbers are in this format:
12345678 and [phone] .. so they are both the same. The only difference is that in one number the country code is missing.
So I do this query in the database:
select the distinct numbers from messages tables..
Now it is taking these both numbers as distinct. But what I want is to take these both numbers as one.
How can I do this? In my DB there are several numbers with different country codes. Some have a country code and some don't, but I want to take both as one. The one in country code and the other without code. How can this be done?
At times now I have an array in which all the distinct numbers are stored. In this array there are numbers like this:
12345678 [phone]
So now I don't know how to make a logic that I can take these numbers as one. If there is any solution for this then please share with some example code.

Answer 1

I don't think you can do this on the database level.
You would have to do something like this:
Create an array of all country codes (including + sign)
Fetch all the numbers from the database
Use array_map() and in the callback run strpos() against each
element in the country code array and if a match is made remove the
country code from the number
Finally after step 4 is finished run the number array through
array_unique()
CODE:
$country_codes = array('+91', '+61');
$numbers_from_db = array('33445322453', '+913232', '3232', '+614343', '024343');
$sanitized_numbers = array_map(function($number) use ($country_codes){
if(substr($number, 0, 1) === "0") {
$number = substr($number, 1);
return $number;
}
foreach($country_codes as $country_code) {
if(strpos($number, $country_code) !== false) {
$number = str_replace($country_code, "", $number);
return $number;
}
}
return $number;
}, $numbers_from_db);
$distinct_sanitized_numbers = array_unique($sanitized_numbers);
Tested and the out put of var_dump($distinct_sanitized_numbers) is:
array(4) {
[0]=>
string(11) "33445322453"
[1]=>
string(4) "3232"
[3]=>
string(4) "4343"
[4]=>
string(5) "24343"
}
