Missleading, unhelpfull message in logs when loading curl and openssl

[Eccenux]

Description

Pretty standard PHP 8.3 installation on Windows with Apache 2.4.

I load this extensions:

extension_dir = "c:/Prog/PHPs/PHP83/ext"

extension=ldap

extension=curl
extension=gd
extension=mbstring
;...
extension=openssl
;...

Resulted in this output (after each Apache restart):

[01-Feb-2024 12:35:41 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'ldap' (tried: c:\Prog\PHPs\PHP83\ext\ldap (The specified module could not be found), c:\Prog\PHPs\PHP83\ext\php_ldap.dll (The specified module could not be found)) in Unknown on line 0
[01-Feb-2024 12:35:41 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'curl' (tried: c:\Prog\PHPs\PHP83\ext\curl (The specified module could not be found), c:\Prog\PHPs\PHP83\ext\php_curl.dll (The specified module could not be found)) in Unknown on line 0

But I expected this output instead:

[01-Feb-2024 12:35:41 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library 'ldap' (found c:\Prog\PHPs\PHP83\ext\php_ldap.dll), but was unable to load it due to: X.

Note that I'm probably missing some DLL files that cURL needs or something... I think. That is why the message is misleading. The path 'c:\Prog\PHPs\PHP83\ext' is valid, and the DLL files of the extensions are all there.

PHP Version

PHP 8.3.2

Operating System

Windows 10 22H2

I'm not sure we can improve here. The error message you see comes from the Win32 API GetLastError after calling LoadLibrary, so it comes straight from Windows.

You could maybe have a list of dependencies for main extensions and check if they are available? (once you get an error).

Or maybe physically check if the dll exists. And if it exists dont' try to load other dlls.

As a side not even when I provide full path:

extension=c:\Prog\PHPs\PHP83\ext\php_curl.dll

Which yields pretty weird results 🙃

[01-Feb-2024 16:03:36 UTC] PHP Warning:  PHP Startup: Unable to load dynamic library

) in Unknown on line 0

Checking if the .dll/.so exists (is readable for php) would at least solve some problems I think.
