Click the link above to learn more PHP Guide by PHP-Learn-It.com Install PHP and MySQL on Windows Installing PHP is easy. You can install PHP on your computer easily with WAMP5. WAMP5 ( www.wampserver.com ) is an open source application which comes with PHP5, Apache web server, MySQL database and phpMyAdmin (MySQL database administration program). Steps for installing PHP and MySQL on Windows Download the latest version of WAMP5 . Run the installation wizard and follow the easy instructions to install WAMP5. Once you’re done installing WAMP5, go to your folder where you installed wamp5. If you didn’t specify which folder to install wamp during the installation wizard, then it should be installed in your C:/ drive, i.e. C:/wamp. Next run the WAMP server file, wampserver.exe in your C:/wamp folder. Once you run the wamp server file, you will see a small icon on your windows tray. PHP GUIDE (BY) PHP-LEARN-IT.com Right click on this icon and then click on ’start All Services. This will start the apache web server along with everything we need to run PHP pages on our machine. That it! You’re almost done. Now open up your web browser and type in http://localhost . You should see the WAMP welcome page. Similarly, you can also install PHP/MySQL on UNIX, LINUX or Mac OS machines. I recommend reading Build PHP/MySQL Driven Websites by Kevin Yank, which covers how to install PHP/MySQL on various platforms with ease and much more. PHP Variables Variables Variables are a mean to store values such as strings or integers so we can easily reuse those values in our code. Every language has its own semantics of defining variables. In PHP, we define a variable starting with a $ sign, then write the variable name and finally assign a value to it. Here is an example below. $variable_name = value; Let’s look at few example of how to declare different types of variables. PHP GUIDE (BY) PHP-LEARN-IT.com Declaring Strings Declaring Integers Declaring Floats and Decimals Remember that, in PHP, we need not to worry about primitive types. In another words, strings and integers are declared the same way. You don’t need to specify its type as shows above. Strings In programming, a string is a sequence of letters, symbols, characters and arithmetic values or combination of all tied together in single or double quotes. Example of a String in PHP Concatenating Strings in PHP You can join two strings by using dot . in between them. PHP GUIDE (BY) PHP-LEARN-IT.com Example 1 – Concatenating PHP Strings Output The above code will print out I Love PHP. PHP is fun to learn. Escaping Special Characters We can escape special characters in a string using backslash. An example would be using quotes inside quotes in a string. Let’s have a look. Notice the \”. We escaped the double quote using a backslash. The above code will output “This is a PHP string example in double quotes” in double quotes. PHP If…Else Statement If-Else Conditions Often in programming while writing code to solve problems, we require to perform certain actions based on certain conditions. To accomplish that, we make use of what’s called if-else statements. if (condition) perform action 1 else perform action 2 The above pseudo-code translates… if the first condition is true, then perform action 1, otherwise, and perform action 2. As an example, let say we want to determine what day of the week it is. For that we would use if statement to determine what day it is. PHP GUIDE (BY) PHP-LEARN-IT.com $day = date(”l”); if ($day == “Saturday”) { echo “It’s party time ”; } else { echo “Ahhh! I hate work days.”; } ?> Notice the curly brackets, those indicate when the condition starts and ends. We need those when we write if…else statements. PHP Loops In PHP, we have 3 main types of loops. Foreach For While Let’s go through each one with examples. Foreach Foreach() loop is most often used to print elements in a array. Foreach Syntax foreach (array as $value) { //code block to be run inside loop } Example of using foreach to print values in an array $browsers = array (”Firefox”, “Internet Explorer”, “Opera”); echo ; ?> The above code will output our drop down box containing three select options, Firefox, Internet Explorer, Opera. For Loop A for() loop is used when we want to execute a block of code for certain number of times. For example, printing a value 5 times. For Loop Syntax for(initialize counter; condition until counter is reached; increment counter) { //execute block of code } Example of for loop to print number through 0 to 5 with PHP For Loop for($i=0; $i<=5; $i=$i+1) { echo $i.” “; } ?> While Loop Just like the for loop, while() loop is used to execute a block of code for certain number of times until the condition in the while evaluate to true. While Loop Syntax while(condition) { //execute block of code } PHP GUIDE (BY) PHP-LEARN-IT.com Example – Print number through 1 to 5 with PHP While Loop Example below prints integers through 1 to 5 echo $i . “
“; $i = $i + 1; } ?> Summary In this guide we covered the basic concepts in PHP. My hope is that this will help you understand the concepts much more clearly and help you get started with PHP programming.
