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 Code:

<?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.

Sample Output:

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
    • Transactions
    • 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.
