How to edit php.ini file via ssh in google cloud

[hannibal]

Hello,
 
Currently I'm learning to use GCE (Google Cloud Engine), Can install VestaCP but there are some module configuration that has not been installed like Imagick and Ioncube.  I stuck in step: 

# vi /etc/php.ini

because it has to add code zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_5.4. so in php.ini in ssh command. I tried to sign in using WinSCP but the php.ini file is Read Only. 

Please advise which command can I use for Insert / Paste, Save and Exitif using vi /etc/php.ini at command prompt gcloud ssh 

Thank you 

Regards,

for an easier way can use nano / pico
if not installed please install first use this command

yum install nano -y

if nano is successfully installed live run this

nano /etc/php.ini

save and exit using command

ctrl + x
