I'm setting Laravel 5.7 on Apache 2.4 using PHP 7.1.26. I configured everything like documentations. But I'm getting the error below:

Call to undefined function Illuminate\Encryption\openssl_cipher_iv_length()

I've already change PHP version to 7.2 and nothing. I've already copied the file libeay32.dll to Apache and nothing

These are my modules in PHP

I've just found there is a case I have to set a full path for PHP extension in php.ini.

When I executed PHP manually, it loaded extensions properly, but when it's via apache, it tried to load from the wrong path.

extension_dir = "C:\full path for PHP ext\ext"

openssl_cipher_iv_length() is a standard PHP function from the OpenSSL module. Your error message says:

undefined function Illuminate\Encryption\openssl_cipher_iv_length()

Note how the function name is preceded by Illuminate\Encryption -- this indicates that PHP thinks the function is located in the Illuminate\Encryption namespace, but it's not. To fix this, you can explicitly associate the function call to the root namespace by prefixing it with a backslash:

\openssl_cipher_iv_length()

This error could also mean that openssl_cipher_iv_length() is simply not available anywhere, and the Illuminate\Encryption namespace is just the last place that it looked. In this case, you'll need to ensure you have the OpenSSL module installed -- but note that the command line config is different than the embedded web server config. I.e., running php -m from the command line might report that OpenSSL is available, but it might not be loaded for the web server version. So run phpinfo() inside a page served by your web server to verify that OpenSSL is indeed loaded.

Just Run composer update command from laravel installation directory And make sure extension=php_openssl.dll is enabled in php.ini

Restart Apache Server...

Enjoy :)
