If you have never had any programming, Algebra, or scripting experience, then the impression of variables might be a new concept to you. Variables are used for storing values, such as numbers, strings or function results, so that they can be used many times in a script.
PHP String
Working with strings is done very often for the web, and PHP is probably one of the best programming languages for manipulating strings :-) I guarante that there are a function or combination of string functions for Anything you ever need.
PHP Operators
An operator is something that you feed with one or more values which yields another value (so that the construction itself becomes an expression). So you can think of functions or constructions that return a value (like print) as operators and those that return nothing (like echo) as any other thing.
PHP If....Else
PHP IF statement is popular and is used to check some conditions and accordingly statements are executed. We can control the html display part also by the IF STATEMENT.
PHP Switch
The switch statement is similar to a series of IF statements on the same expression. In many occasions, you may want to compare the same variable (or expression) with many different values, and execute a different piece of code depending on which value it equals to. This is exactly what the switch statement is for.
PHP Arrays
An array is a data structure that stores one or more values in a single value. For experienced programmers it is important to note that PHP's arrays are actually maps.
PHP Looping
A FOR loop is very similar to a WHILE loop in that it continues to process a block of code until a statement becomes false, however everything is defined in a single line.
PHP Functions
A function is just a name we give to a block of code that can be executed whenever we need it. This might not seem like that big of an idea, but believe me, when you understand and use functions you will be able to save a ton of time and write code that is much more readable!
PHP Forms
PHP Forms is an all-in-one web based form builder that allows you to create online forms, validate and collect data fast and with minimum effort. Web forms are easily integrated into your website: just insert the php form code or html form code into your page.
PHP $_GET
The $_GET variable is an array of variable names and values sent by the HTTP GET method. The $_GET variable is used to collect values from a form with method="get". Information sent from a form with the GET method is visible to everyone and it has limits on the amount of information to send.
PHP $_POST
The $_POST variable is an array of variable names and values sent by the HTTP POST method. The $_POST variable is used to collect values from a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
