Be carefull while using phpinfo script in EC2 beanstalk

Currently I tried some EC2 beanstalk instances in AWS.
While working I found that in php environment setting there was a parameter for Database username and password.
For easy go I set the parameter with mysql Database username and password.

After doing this I created a php info script in Web directory to check installed php extension

vi phpinfo.php

After hitting the URL with phpinfo.php in Web browser I found that the Database username and password was visible in php info page.
Hence be careful with php info and setting Database username and password in php environment.
