PHP Exercises : Get PHP version and configuration information
PHP : Exercise-1 with Solution
Write a PHP script to get the PHP version and configuration information.
Sample Solution: -
<?php phpinfo(); ?>
Note: phpinfo() outputs a large amount of information about the current state of PHP. This includes information about PHP compilation options and extensions, the PHP version, server information and environment, the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License.
phpinfo() PHP Version => 5.6.11-1ubuntu3.4 System => Linux server 4.4.0-47-generic #68-Ubuntu SMP Wed O ct 26 19:39:52 UTC 2016 x86_64 Server API => Command Line Interface Virtual Directory Support => disabled Configuration File (php.ini) Path => /etc/php5/cli Loaded Configuration File => /etc/php5/cli/php.ini Scan this dir for additional .ini files => /etc/php5/cli/con f.d Additional .ini files parsed => /etc/php5/cli/conf.d/05-opca che.ini, /etc/php5/cli/conf.d/10-pdo.ini, /etc/php5/cli/conf.d/20-gd.ini, /etc/php5/cli/conf.d/20-json.ini, /etc/php5/cli/conf.d/20-readline.ini, /etc/php5/cli/conf.d/20-ssh2.ini ......

PHP: Tips of the Day
Why shouldn't I use mysql_* functions in PHP?
The MySQL extension:
- Is not under active development
- Is officially deprecated as of PHP 5.5 (released June 2013).
- Has been removed entirely as of PHP 7.0 (released December 2015)
- This means that as of 31 Dec 2018 it does not exist in any supported version of PHP. If you are using a version of PHP which supports it, you are using a version which doesn't get security problems fixed.
- Lacks an OO interface
- Doesn't support:
- Non-blocking, asynchronous queries
- Prepared statements or parameterized queries
- Stored procedures
- Multiple Statements
- The "new" password authentication method (on by default in MySQL 5.6; required in 5.7)
- Any of the new functionality in MySQL 5.1 or later
Since it is deprecated, using it makes your code less future proof.
Lack of support for prepared statements is particularly important as they provide a clearer, less error-prone method of escaping and quoting external data than manually escaping it with a separate function call.
