Php
PHP is a server-side scripting language designed for web development but also used as a general-purpose
programming language. PHP is now installed on more than 244 million websites and 2.1 million web servers.
Originally created by Rasmus Lerdorf in 1995, the reference implementation of PHP is now produced by The PHP Group.
While PHP originally stood for Personal Home Page,
it now stands for PHP: Hypertext Preprocessor, a recursive acronym.[5]
Detail
PHP code is interpreted by a web server with a PHP processor module which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data.
It has also evolved to include a command-line interface capability and can be used in standalone graphical applications.[6]
PHP is free software released under the PHP License, which is incompatible with the GNU General Public License (GPL) due to restrictions on the usage of the term PHP.[7] PHP can be deployed on most web servers and also as a standalone shell on almost every operating system and platform, free of charge.[8]
MySql .
MySQL (/maɪ ˌɛskjuːˈɛl/ "My S-Q-L",[3] officially, but also called /maɪ ˈsiːkwəl/ "My Sequel") is (as of 2008) the world's most widely used[4][5] open source relational database management system (RDBMS)[6] that runs as a server providing multi-user access to a number of databases. It is named after co-founder Michael Widenius' daughter, My.[7] The SQL phrase stands for Structured Query Language.[3]
The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation.[8]
MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack (and other 'AMP' stacks). LAMP is an acronym for "Linux, Apache, MySQL, Perl/PHP/Python." Free-software-open source projects that require a full-featured database management system often use MySQL.
For commercial use, several paid editions are available, and offer additional functionality. Applications which use MySQL databases include: TYPO3, MODx, Joomla, WordPress, phpBB, MyBB, Drupal and other software. MySQL is also used in many high-profile, large-scale websites, including Wikipedia,[9] Google[10][11] (though not for searches), Facebook,[12][13][14] Twitter,[15] Flickr,[16] and YouTube.[17]
InterFace .
MySQL is a relational database management system (RDBMS), and ships with no GUI tools to administer MySQL databases or
manage data contained within the databases. Users may use the included command line tools, or use MySQL "front-ends",
desktop software and web applications that create and manage MySQL databases, build database structures, back up data,
inspect status, and work with data records. The official set of MySQL front-end tools, MySQL Workbench
is actively developed by Oracle, and is freely available for use.
