I checked my PHP version and it's 5.6.31. Also, I can not access wp-admin.

The MySQL extension:

• Is not under active development
• Is officially [deprecated][1] as of PHP 5.5 (released June 2013).
• Has been removed entirely as of PHP 7.0 (released December 2015)
• Lacks an OO interface
• Doesn't support:
  • Non-blocking, asynchronous queries
  • [Prepared statements][2] or parameterized queries
  • Stored procedures
  • Multiple Statements
  • Transactions
  • The "new" password authentication method (on by default in MySQL 5.6; required in 5.7)
  • All of the functionality in MySQL 5.1

Since it is deprecated, using it makes your code less future proof.
