phdevutils/psic

The Philippine Standard Industrial Classification (PSIC 2009) for PHP — the 21 sections (1-letter codes A–U) and 88 divisions (2-digit codes) with lookup, validation, and keyword-search helpers. PHP companion to the npm package @ph-dev-utils/psic.

Pairs naturally with phdevutils/business for tagging a registered company's industry.

composer require phdevutils/psic

Quick start

use PhDevUtils\Psic\Psic;

Psic::findSection('C');           // ['code' => 'C', 'title' => 'Manufacturing', 'divisions' => ['10', …, '33']]
Psic::findDivision('62');         // ['code' => '62', 'title' => 'Computer programming, …', 'section' => 'J']
Psic::sectionOf('62');            // ['code' => 'J', 'title' => 'Information and communication', …]

Psic::listDivisions(['section' => 'C']); // the 24 manufacturing divisions (10–33)
Psic::search('insurance');               // ['sections' => [K], 'divisions' => [65, 66, …]]

Scope & data

This release covers the two stable top levels of PSIC 2009 — sections and divisions — which is what most industry-categorisation use cases need. The finer group / class / sub-class levels (3–5 digit codes) are out of scope for now.

Data is transcribed from the PSA/NSCB 2009 PSIC codes document (patterned after the UN ISIC Rev.4 at the division level). PSIC 2019 is a newer revision — confirm against the PSA when the latest codes matter. Not affiliated with the PSA/NSCB.
