introduction
Introduction
  • PHP is a Scripting Language that was originally designed for web development to produce dynamic web pages.
  • For this purpose, PHP code is embedded into HTML
  • PHP was created by Rasmus Lerdrof in 1995.
  • PHP Originally stood for “Personal Home Page”.
usage
Usage
  • PHP is a general purpose scripting language that is specially suited to server-side web development where PHP generally runs on a web server.
  • PHP is also used for command-line scripting and client-side GUI applications
  • PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content.
  • PHP can be developed on most webs servers, many operating systems and platforms, and can be used with many relational database management systems..

Small Sample Code

<html>

<head>

<<title>PHP Test</title>

</head>

<body>

<?php

Echo “Hello World”;

?>

</body>

output
Output

Here is the output “Hello World”.

  • PHP only parses code within its delimiters. Anything outside its delimiters is sent directly to the output and is not processes by PHP.
  • The most common dilimiters are

<?php to open and ?>

<script language=”php”>

</script>

<?=(which is used to echo back a string or variable ) and ?>

<% or <%= and %>

data types
Data Types
  • PHP stores whole numbers in a platform-dependent range.
  • This range is typically that of 32-bit signed integers. Unsigned integers are converted to signed values in certain situations.
  • Arrays can contain elements of any type that handle in PHP.
  • Including resources, objects, and even other arrays.
  • PHP also supports strings, which can be used with single quotes, double quotes, or heredoc syntax.
speed optimization
Speed Optimization
  • PHP scripts are stored as human-readable source code and are compiled on-the fly to an internal format that can be executed by the PHP engine.
  • Code optimizers aim to reduce the runtime of the compiled code by reducing its size and making other changes that can reduce the execution time with the goal of improving performance.
resources
Resources
  • PHP includes free and open source libraries.
  • PHP is a fundamentally internet-aware system.
  • Many database servers, embedded SQL libraries such as embedded postgreSQL,MYSQL and SQLite, LDAP servers, and others.
  • PHP allows developers to write extensions in C to add functionality to the PHP language.
  • These can then be compiled into PHP or loaded dynamically at runtime.
