laravel 错误
Call to undefined function Illuminate\Encryption\openssl_cipher_iv_length()
phpinfo()
OpenSSL support disabled (install ext/openssl)
下载https://windows.php.net/downloads/php-sdk/deps/vc15/x64/openssl-1.1.1a-vc15-x64.zip
解压后bin目录能看到libcrypto-1_1-x64.dll和libssl-1_1-x64.dll，两个文件都拷到php目录和apache的bin下
开启extension=openssl
重启Apache就好了
