Bug #74563 [Com]: curl_exec() throws internal error in curl_error()

Edit report at https://bugs.php.net/bug.php?id=74563&edit=1 ID: 74563 Comment by: danack@php.net Reported by: jeremys at ha dot com Summary: curl_exec() throws internal error in curl_error() Status: Open Type: Bug Package: cURL related Operating System: RHEL 7.3 PHP Version: 7.1.4 Block user comment: N Private report: N New Comment: In fact - please can you just double check that you are seeing the error from the code you have listed here. I strongly suspect you have OPCache running and the error you are seeing is from code that has been cached in memory, rather than running the latest version of that file.

The error is as follows: curl_error() expects parameter 1 to be resource, boolean given As you can see in the sample script, there is no explicit call to curl_error(), yet the above error is seen. I've only been able to reproduce via Apache, not via cli. Apache/2.4.6 (Red Hat Enterprise Linux) PHP 7.1.3 (part of Zend Server 9.1) - I assume 7.1.4 as well since there are no relevant changes to the curl interface in the PHP source code libcurl 7.29.0 Test script: --------------- <?php ini_set( 'display_errors', 1 ); ini_set( 'error_reporting', E_ALL ); set_error_handler( function ( ...$error ) { array_pop( $error ); print_r( $error ); die(); }); $resource = curl_init(); curl_setopt( $resource, CURLOPT_URL, 'http://127.0.0.1:1' ); curl_setopt( $resource, CURLOPT_RETURNTRANSFER, 1 ); curl_exec( $resource ); echo 'Script finished.'; Expected result: ---------------- Script finished. Actual result: -------------- Array ( [0] => 2 [1] => curl_error() expects parameter 1 to be resource, boolean given [2] => /usr/local/apache/htdocs2/curl-error-test.php [3] => 16 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74563&edit=1
