Stdlib: ext/odbc — odbc_connect/odbc_exec SQL ODBC API missing (ext/odbc)

[PurHur]

Category

stdlib

Problem

ext/odbc procedural API (odbc_connect, odbc_exec, odbc_fetch_row, odbc_result, …) is absent. Legacy ERP/BI scripts and Windows/Linux ODBC integrations depend on this extension. function_exists('odbc_connect') → false on VM.

php-src reference

• php/php-src ext/odbc/php_odbc.c — connection + statement lifecycle
• php/php-src ext/odbc/odbc_driver.c — unixODBC / iODBC driver bridge
• Phase 1 surface: odbc_connect, odbc_pconnect, odbc_close, odbc_exec, odbc_fetch_row, odbc_result, odbc_num_rows, odbc_error, odbc_errormsg

Repro (failure today)

<?php
echo function_exists('odbc_connect') ? "yes\n" : "no\n";
echo function_exists('odbc_exec') ? "yes\n" : "no\n";

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php -r "var_export(function_exists(\"odbc_connect\"));"
php bin/vm.php -r "var_export(function_exists(\"odbc_connect\"));"
'

Runtime	function_exists('odbc_connect')
Zend + ext/odbc	true
bin/vm.php	false

Scope (this repo)

Path	Work
ext/odbc/Module.php	New extension module
VM resources	ODBC link + result handles
Native	Thin unixODBC FFI/wrapper (document unixodbc-dev in Docker)
Tests	test/compliance/cases/stdlib/odbc_exists.phpt; optional @group odbc DSN smoke
Matrix	script/capability-matrix.php

PHP-in-PHP: connection bookkeeping in ext/odbc/*.php; C only for ODBC driver ABI.

Done when

• Phase 1 builtins registered; existence repro passes on VM
• odbc_connect with invalid DSN → false + warning (Zend parity)
• ./script/ci-fast.sh --filter odbc_exists green
• Distinct from Stdlib: ext/pdo — PDO connect/query/fetch subset (ext/pdo parity) #3367 PDO / Stdlib: ext/mysqli — mysqli_connect/query/fetch (ext/mysqli parity) #3435 mysqli

Verification

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && vendor/bin/phpunit --filter odbc_exists'

Verification

• php bin/vm.php test/repro/issue_6293_odbc_phase1.php → yes / yes / false / warned
• vendor/bin/phpunit --filter 'odbc_exists|odbc_connect_invalid' → OK (4 tests)

Phase 1 done: builtins registered; invalid DSN → false + SQLConnect warning (php-src-strict).
