Bug #79051 [Fbk->Asn]: putenv variables not accessible to dependent functions in Windows CLI

Edit report at https://bugs.php.net/bug.php?id=79051&edit=1 ID: 79051 User updated by: danielklein at airpost dot net Reported by: danielklein at airpost dot net Summary: putenv variables not accessible to dependent functions in Windows CLI -Status: Feedback +Status: Assigned Type: Bug Package: PHP options/info functions Operating System: Windows 10 PHP Version: 7.3.13 Assigned To: cmb Block user comment: N Private report: N New Comment: The first var_dump(getenv('all_proxy')); returns bool(false). var_dump(putenv('all_proxy=localhost:5678')); returns bool(true). The second var_dump(getenv('all_proxy')); returns string(14) "localhost:5678". It's the thread safe build: PHP 7.3.9 (cli) (built: Aug 28 2019 09:28:48) ( ZTS MSVC15 (Visual C++ 2017) x64 ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.9, Copyright (c) 1998-2018 Zend Technologies with Xdebug v2.7.2, Copyright (c) 2002-2019, by Derick Rethans Just to confirm, you did run this on Windows? The bug is not present on Ubuntu, and I assume other Linux varieties. Previous Comments: ------------------------------------------------------------------------ [2020-01-01 12:39:00] cmb@php.net I cannot reproduce the reported behavior. What do the putenv() and getenv() calls return (use var_dump instead of echo or ignoring the return value)? Also, are you using NTS or ZTS builds? ------------------------------------------------------------------------ [2020-01-01 02:28:36] danielklein at airpost dot net "Edit" won't let me edit the bug report. Actual result: ========== first run without proxy <html> <head></head> <body>.</body> </html> ========== second run with proxy override localhost:5678 <html> <head></head> <body>.</body> </html> ------------------------------------------------------------------------ [2020-01-01 02:24:52] danielklein at airpost dot net Description: ------------ In Windows CLI, setting an environment with putenv(), such as "all_proxy" which is supposed to affect cURL, has no effect on later function calls. The test script works as expected on Ubuntu CLI, but not Windows CLI. Test script: --------------- <?php function search() { $url = 'x3m.dev'; $curl = curl_init(); curl_setopt_array($curl, [ CURLOPT_RETURNTRANSFER => 1, CURLOPT_URL => $url, ]); $data = curl_exec($curl); if (!$data) { throw new Exception('An error occurred while trying to process the request.'); } return $data; } function do_curl_request() { echo getenv("all_proxy") . "\n\n"; try { echo search(); } catch (Exception $e) { echo $e->getMessage(); } echo "\n\n"; } echo "========== first run without proxy\n"; do_curl_request(); putenv("all_proxy=localhost:5678"); echo "========== second run with proxy override\n"; do_curl_request(); Expected result: ---------------- ========== first run without proxy <html> <head></head> <body>.</body> </html> ========== second run with proxy override localhost:5678 An error occurred while trying to process the request. Actual result: -------------- ========== first run without proxy <html> <head></head> <body>.</body> </html> ========== second run with proxy override localhost:5678 An error occurred while trying to process the request. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79051&edit=1
