Edit report at https://bugs.php.net/bug.php?id=71947&edit=1 ID: 71947 Updated by: sixd@php.net Reported by: sergei dot solomonov at gmail dot com Summary: Bizarre behavior oci8 with call_user_func_array -Status: Open +Status: Duplicate Type: Bug Package: OCI8 related Operating System: Ubuntu 15.04 PHP Version: 7.0.4 Block user comment: N Private report: N New Comment: See bug #71148 Previous Comments: ------------------------------------------------------------------------ [2016-04-12 02:50:37] sergei dot solomonov at gmail dot com 2sixd, yes that works. Like I said, some slight changes may result to different output. Now I'm trying to identify this bug with php 7.0.5. This behaviour were changed, but still buggy. ------------------------------------------------------------------------ [2016-04-12 02:24:13] sixd@php.net You need to make sure the memory address being bound is still available at time of OCI8 execute. However ref counting in PHP core changed a lot in PHP 7 as part of the performance work and the ref count of $v in bindVal() is different from that in PHP 5.6. This works in PHP 7: $v = 'expected value'; (new dbTest)->bindVal([&$v]) ->execute() ->result(); ------------------------------------------------------------------------ [2016-04-01 17:31:31] sergei dot solomonov at gmail dot com Sorry wrong php version in description, it tested with 7.0.4 ------------------------------------------------------------------------ [2016-04-01 17:22:07] sergei dot solomonov at gmail dot com Description: ------------ Os info: Ubuntu 15.04, Linux 4.2.0-19-generic Php version: 7.0.5 Configure command: './configure' '--enable-zip' '--enable-intl' '--with-oci8' '--disable-cgi' '--with-apxs2=/usr/local/apache/bin/apxs' '--enable-opcache' '--enable-sigchild' '--enable-mbstring' '--with-xsl' '--with-gd' '--with-config-file-scan-dir=/usr/local/apache/conf' '--with-openssl' '--with-curl' '--with-zlib' '--enable-timezonedb' Php ini: php.ini-production, no changes I'm in migrating process from php 5.6.9 to 7.0.5. I noticed very strange errors with oci8 + call_user_func_array functions. Test script shows how to get other bind value rather then you were supplied as a parameter. If you'll try to do some little changes you may have different results. Also I had a segfaults, but now I can't reproduce it. Test script: --------------- class dbTest { private $stmt; public function __construct() { $conn = oci_connect('user', 'password', 'dbmane'); $this->stmt = oci_parse($conn, 'select :bindValue as result from dual'); } public function runOciFunc($funcName, array $funcArgs) { call_user_func_array("oci_$funcName", $funcArgs); } public function bindVal(array $bind) { foreach ($bind as $k => $v) { $this->runOciFunc('bind_by_name', [$this->stmt, ':bindValue', &$v]); } return $this; } public function execute() { $this->runOciFunc('execute', [$this->stmt]); return $this; } public function result() { var_dump(oci_fetch_assoc($this->stmt)); } } (new dbTest)->bindVal(['expected value']) ->execute() ->result(); Expected result: ---------------- array(1) { ["RESULT"]=> string(14) "expected value" } Actual result: -------------- array(1) { ["RESULT"]=> string(11) "oci_execute" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71947&edit=1
