PHP Script for HLR lookup

The mobile phone prefix of a phone number in our country does not always indicate the mobile phone provider; as customers can move numbers between providers (portability).

This project takes an input csv file, and looks up mobile numbers in that CSV against an API that looks up the mobile provider that a particular customer uses. It then presents an analysis of the mobile numbers in that CSV, and an analysis of the mobile provider.


API example

1. 1st call send phone number (mdisdn). It returns an id.

# curl -X POST [login to view URL] -H 'Authorization: AccessKey SSdwna1fPL5pCT0J2ecMoobS6A' -d "msisdn=353872227869" -d "reference=YourReference"

{"id":"71e3f581793e4d64a7ea1ad5a2043977","href":"[login to view URL]","msisdn":353872227869,"network":null,"details":null,"reference":"YourReference","status":"sent","createdDatetime":"2018-10-30T10:53:21+00:00","statusDatetime":"2018-10-30T10:53:21+00:00"}

2. 2nd call send phone number (mdisdn). It returns an a details array containing locations_msc, and ported (the fields we will use).

# curl -X GET [login to view URL] -H 'Authorization: AccessKey SSdwna1fPL5pCT0J2ecMoobS6A'

{"id":"71e3f581793e4d64a7ea1ad5a2043977","href":"[login to view URL]","msisdn":353872227869,"network":27205,"details":{"status_desc":null,"imsi":"272057035605903","country_iso":"IRL","country_name":"Ireland","location_msc":"35383","location_iso":"ie","ported":1,"roaming":0},"reference":"YourReference","status":"active","createdDatetime":"2018-10-30T10:53:22+00:00","statusDatetime":"2018-10-30T10:53:24+00:00"}


Static data.

The below is used:

- to allow a CSV line to be processed. If the number is not one of these patterns then it is skipped.

- to allow for analysis of the HLR lookup details that are returned from the API call.

$provider ['083-three ']='(35383|083)\\d{7}';

$provider ['085-eir ']='(35385|085)\\d{7}';

$provider ['086-o2 ']='(35386|086)\\d{7}';

$provider ['087-vodafone']='(35387|087)\\d{7}';

$provider ['089-tesco ']='(35389|089)\\d{7}';

-- Parameters to script:

csv - name of input csv file

field - number of field containing phone number to be analyised. 1st is 1.

number - only perform the lookup on a max of this number. The max is the number of successful HLR lookups to perform.

-- Sample Output:

php ./[login to view URL] --csv [login to view URL] --field 4 --number 5

Numbers read: 7

Numbers matching pattern: 6

Numbers whose HLR we could lookup: 5

Numbers which appear as ported: 2

Finished - Analyst of HLRs:


083-three: 20.0%,2

086-o2: 10.0%,10

089-tesco: 70.0%,7



Location Msc5

083-threee: 20.0%,2

086-o2: 20.0%,2

089-tesco: 60.1%,6



Log file of all API calls and responses saved to "HLR-08:55:30-30:10:[login to view URL]".


Note that lookups cost e0.015 each so testing should use small numbers (not 100's).
