What you’ll learn:
php
jsp
Forms
Requirements:
php installed in your system
visual studio code
Description:
PHP started out as a small open source project that evolved as more and more people found out how useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994.
PHP is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Web Development Domain. I will list down some of the key advantages of learning PHP:
PHP is a recursive acronym for “PHP: Hypertext Preprocessor”.
PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e-commerce sites.
It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.
PHP is pleasingly zippy in its execution, especially when compiled as an Apache module on the Unix side. The MySQL server, once started, executes even very complex queries with huge result sets in record-setting time.
PHP supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4 added support for Java and distributed object architectures (COM and CORBA), making n-tier development a possibility for the first time.
PHP is forgiving: PHP language tries to be as forgiving as possible.
PHP Syntax is C-Like.
In order to develop and run PHP Web pages three vital components need to be installed on your computer system.
Web Server − PHP will work with virtually all Web Server software, including Microsoft’s Internet Information Server (IIS) but then most often used is freely available Apache Server.
Database − PHP will work with virtually all database software, including Oracle and Sybase but most commonly used is freely available MySQL database.
PHP Parser − In order to process PHP script instructions a parser must be installed to generate HTML output that can be sent to the Web Browser. This tutorial will guide you how to install PHP parser on your computer.
Performance:
PHP script is executed much faster than those scripts which are written in other languages such as JSP and ASP. PHP uses its own memory, so the server workload and loading time is automatically reduced, which results in faster processing speed and better performance.
Open Source:
PHP source code and software are freely available on the web. You can develop all the versions of PHP according to your requirement without paying any cost. All its components are free to download and use.
Familiarity with syntax:
PHP has easily understandable syntax. Programmers are comfortable coding with it.
Embedded:
PHP code can be easily embedded within HTML tags and script.
Platform Independent:
PHP is available for WINDOWS, MAC, LINUX & UNIX operating system. A PHP application developed in one OS can be easily executed in other OS also.
Database Support:PHP supports all the leading databases such as MySQL, SQLite, ODBC, etc.
Error Reporting –
PHP has predefined error reporting constants to generate an error notice or warning at runtime. E.g., E_ERROR, E_WARNING, E_STRICT, E_PARSE.
Loosely Typed Language:
PHP allows us to use a variable without declaring its datatype. It will be taken automatically at the time of execution based on the type of data it contains on its value.
Web servers Support:
PHP is compatible with almost all local servers used today like Apache, Netscape, Microsoft IIS, etc.
Security:
PHP is a secure language to develop the website. It consists of multiple layers of security to prevent threads and malicious attacks.
Control:
Different programming languages require long script or code, whereas PHP can do the same work in a few lines of code. It has maximum control over the websites like you can make changes easily whenever you want.
A Helpful PHP Community:
It has a large community of developers who regularly updates documentation, tutorials, online help, and FAQs. Learning PHP from the communities is one of the significant benefits.PHP is widely used in web development nowadays. PHP can develop dynamic websites easily. But you must have the basic the knowledge of following technologies for web development as well.
HTML
CSS
JavaScript
Ajax
XML and JSON
jQuery
Prerequisite
Before learning PHP, you must have the basic knowledge of HTML, CSS, and JavaScript. So, learn these technologies for better implementation of PHP.
