BASIC PHP [Level: Beginners]

Basic Syntax

Starting a PHP File

    <?php



  //Your code could go here



?>

Comments
Comments are section or line of code that will not be executed in the Site

    <?php

   //This is just a single line comment

   /*

    This is a multi line comment

  */

?>

Echo
Echo is a function that is built into php that is used to output text tot he screen you can aloes use it to output html code

    ?php

     echo "Hello World";

?>

String Concatenation
String Concatenation is used to bind two string together this is helpful once you learn about variables

    <?php

    echo "Hello " . "World";

?>

The output would be

    Hello World

Includes
Includes are used to add a php file inside another one so you can use there functions(we will do functions soon) and there variables

    <?php

  include "login.php";

?>

Now that you know the basic Syntax of PHP we will move on to Variables

Variables

Basic Variable
A Basic Variable is used to store some type of value. to start off a variable in php you have to use a $ then after that you put what ever name you would like the Followed with a =
then the variable value

    <?php

   $thename = "Hello World";



   echo $thename;

?>

Constants
A Constant is a variable that can not be unset or changed once the code has been executed.
To start constant you use the function define()

    <?php

   /*the define functions takes 3 parameters: name, value, case insensitive

   Example*/

   define("NGU", "isOnline");

   // Using case insensitive

   define("NGU1", "isOnline", true);

   //You and aloes define Constants like this

   const NGU2 = "isOnline";

?>

This you can store in a variable

Int = A Number
String = A word Example: "Hello World"
Bool = True or False
Float = 1.0
Array = More then one value
NULL = Nothing

This you can store in a variable
Arrays are variable that you can store more then 1 value in this is helpful when when returning data from a database

    <?php

   $myarray = array(1 => "Lachie444", 2 => "Jelly");

   echo $myarray[1];

?>

Now that you know the basic of variables we will move onto functions

Functions

Functions are helpful so you dont have to have the same code over and over again in your code and to call it in another file when included.

Basic Functions

To start off a function you use (function) followed by the name you would like end it with () Example [ function my_function() ]

    <?php

     

   function my_function()

   {

       //In here you put code that will executed when the function is called

       echo "Hello World";

   }

    

   //Calling the function

     my_function();



?>

The output would be

    Hello World

Function Parameters

Function Parameters are arguments are passed by the function to the function code with a value

    <?php



     //Here's a example   $string This is argument for the function my_function

     function my_function($string)

     {

        echo $string;

     }



     //Calling the function with the argument 

      my_function("Hello World");

?>

The output would be

    Hello World

This is the end of this tutorial of basic PHP in the future ill make another tutorial going into some more advanced PHP Example: MySql, Classes and more

Hmm, from what I've seen, the best programmers/coders are the worst spellers lol. I'll have to look into PHP once I finish delving into Javascript :p
