Answer 1

PHP7.1.12 CentOS

I build php by myself.

/usr/local/php71/bin/php -r "ftp_ssl_connect('server1.example.com');"

PHP Fatal error:  Uncaught Error: Call to undefined function ftp_ssl_connect() in Command line code:1

resolve：

# /root/php-7.1.12/ is php source dir
cd /root/php-7.1.12/ext/ftp/

# /usr/local/php71/ is php dir
/usr/local/php71/bin/phpize

# the param --with-openssl-dir is very important
./configure --with-php-config=/usr/local/php71/bin/php-config --with-openssl-dir

make
make install

vim /usr/local/php71/lib/php.ini
# add last line
extension=ftp.so

service php-fpm reload

check：

# method 1
/usr/local/php71/bin/php -r "phpinfo();" | grep FTP

FTP support => enabled
FTPS support => enabled

# method 2
/usr/local/php71/bin/php -r "ftp_ssl_connect('server1.example.com');"

PHP Warning:  ftp_ssl_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known in Command line code on line 1

done!
