ID: 48819 Comment by: [email protected] Reported by: pkwan at advsofteng dot net Summary: dl function is undefined Status: Re-Opened Type: Bug Package: Scripting Engine problem Operating System: Multiple PHP Version: 5.3.0-5.3.3 Block user comment: N Private report: N New Comment: For those still struggling with this problem, we reverted the patch as shown on http://www.mail-archive.com/[email protected]/msg39628.html and the problem went away. IMHO this patch should be reversed, as it says "Disable dl() in CGI and FastCGI modes" while the website states "The only SAPI's that allow dl() are: [...] CGI" Previous Comments: ------------------------------------------------------------------------ [2011-01-12 18:45:41] [email protected] We are currently experiencing the same problem on php-5.3.3. To confuse the matter even more: We use an Apache/2.2.14 (Debian) server with suexec enable. * When running the CGI-binary from the command line everything works fine, dl() is available and works as expected. * When running the CGI-binary through apache2's suexec command everything works. * The CLI binary also works without any problem. * Only when running php in CGI/FastCGI mode through Apache's suexec things stop working and php dies with the "Call to undefined function dl()", instead of the expected correct behaviour, or even throwing an error. ------------------------------------------------------------------------ [2010-08-16 17:13:17] [email protected] this bug is not bogus. it's either valid or should be reclassified as a documentation bug. the manual says (as of August 16, 2010): 5.3.0 dl() is now disabled in some SAPI's due to stability issues. The only SAPI's that allow dl() are: CLI, CGI and Embed. in fact, a peek at php-5.3.3/ext/standard/dl.c suggests that the manual is quite misleading as it leaves the reader thinking that dl() will work in non-TS versions of CLI, CGI and Embed just find, when in fact the function is E_DEPRECATED across the board: if ((strncmp(sapi_module.name, "cgi", 3) != 0) && (strcmp(sapi_module.name, "cli") != 0) && (strncmp(sapi_module.name, "embed", 5) != 0) ) { #ifdef ZTS php_error_docref(NULL TSRMLS_CC, E_WARNING, "Not supported in multithreaded Web servers - use extension=%s in your php.ini", filename); RETURN_FALSE; #else php_error_docref(NULL TSRMLS_CC, E_DEPRECATED, "dl() is deprecated - use extension=%s in your php.ini", filename); #endif } that's correct as long as i run php-cgi.exe on the command line: var_dump(extension_loaded('sqlsrv')); dl('php_sqlsrv.dll'); var_dump(extension_loaded('sqlsrv')); run with php-cgi -nq -d extension_dir=$somewhere -d error_reporting=-1 test.php gives bool(false) bool(true) however, running the same php-cgi inside Apache 2.2 on Windows, the dl() function does not exist. tested with 5.3.3-nts-vc9. ------------------------------------------------------------------------ [2009-07-06 17:32:18] pkwan at advsofteng dot net This is definitely a bug. According to PHP 5.3 documentation, dl should work, at least for CLI, CGI and Embed. Pease read the PHP documentation. The PHP 5.3 documentation for "dl" says: This function now throws an E_DEPRECATED notice on all sapi's except for CLI, CGI and Embed. Also, the PHP 5.3 change log "http://www.php.net/ChangeLog-5.php"; says: Changed dl() to be disabled by default. Enabled only when explicitly registered by the SAPI. Currently enabled with cli, cgi and embed SAPIs. (Dmitry) So the above clearly says dl should work on CLI, CGI and Embed SAPI. I am testing using CGI, and it does not work. Therefore it is a bug. Furthermore, from the PHP documentation on dl, the E_DEPRECATED is only a "notice", not an error. So dl should work in all other SAPI as well. ------------------------------------------------------------------------ [2009-07-06 16:24:10] [email protected] Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php ------------------------------------------------------------------------ [2009-07-06 16:07:01] dani88elx at gmail dot com This is not a bug. dl() is deprecated from 5.3 version ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
