PHP can be considered more as a revolution in the web development arena. Beginning with scripting of simple web pages, PHP today has evolved into a language that powers almost 60% of the web . Well, it has been extensively modified to develop frameworks and content management systems to ease the tasks of developers. Essentially, frameworks have some pre-coded functionalities that developers require on a regular basis and content management systems are built with the end user in mind. We assume that Core PHP means solving a Mathematical problem by using paper and pen. Frame work means solving Mathematical problem by using a calculator. Core PHP-Solving Mathematical Problem Only some students can achieve results by using paper and pen as same as in PHP. Only a few of the developers can write the code in an easy way and reliable format. Core PHP uses the PHP script in its purest form . A developer needs to know the language thoroughly in order to write a clear and co...

What is SQL Injection? SQL Injection is an injection attack wherein an attacker can execute malicious SQL statements that control a web application’s database server.

These annotations are not shown to the end-user, but are needed by the ‘machine’ to read and subsequently process the text correctly.An XML document is plain text and contains tags delimited by < and >. XML plays a significant role in the present world of web development, it is perfectly useful for those who wish to make use of web technologies for distributing information across the web. XML is used to format a document with a web browser. It is an influential and effectual tool to process a document’s contents and therefore, creating own tags is possible with XML. It works well with any operating system and maintains a great amount of flexibility, which is very essential for the web development scenario.  Parsing an XML Document Parsing is usually applies to text  it is   the act of reading t...
