[mmojadad]

Hi I modified php.ini as following but i can not see zstd in phpinfo.php report. How can be sure extension is enabled? php_zstd.dll NTS placed in C:\Program Files\PHP\v7.4.24\ext

[PHP_Zstandard] zend_extension=php_zstd.dll

• Is the extension_dir correct (you may have the wrong reference)
• Are there any error or warning messages (you may be using the wrong version)

• Is the extension_dir correct (you may have the wrong reference) Yes, Sure. All other extensions like Zend OPcache v7.4.24 there working fine!
  • Are there any error or warning messages (you may be using the wrong version) Yes, As following PHP Warning: Failed loading Zend extension 'php_zstd.dll' (tried: C:\Program Files\PHP\v7.4.24\ext\php_zstd.dll (The specified module could not be found.), C:\Program Files\PHP\v7.4.24\ext\php_php_zstd.dll.dll (The specified module could not be found.)) in Unknown on line 0

For the build available in pecl.php.net, libzstd.dll must be in the PHP executable directory (or whereever Windows can find,) while php_zstd.dll should still be in ext/.

@ranvis Already php_zstd.dll is in C:\Program Files\PHP\v7.4.24\ext\

If the distribution has libzstd.dll, then that DLL is required for Windows to load php_zstd.dll. And Windows cannot find libzstd.dll if it is in ext/ directory. Try moving it to the same directory as php.exe.

PHP_DIR/
  ext/
    php_zstd.dll
  libzstd.dll
  php.exe

@ranvis Yes! I moved libzstd.dll to the same directory as php.exe and now working fine. Thanks
