PHP Basic Syntax

PHP Programming

PHP Syntax can be place at anywhare in the document. PHP code must be placed between <?php /your code here/ ?>. A PHP file normally contains HTML tags, and PHP file extension is .php. This is example of PHP file.

<?php
    //your code here       
?>

This is fully PHP code with HTML tags.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>//your title here</title>
    </head>
    <body>
        <?php
            //your code here
        ?>
    </body>
</html>

PHP no keywords (echo, if, else, etc), classes, function (method) are not must have an uppercase, capitalized, and toggle case system because legal and still can be used. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        ECHO "Hello World!<br>";
        Echo "Hello World!<br>";
        eCHO "Hello World!<br>";
        ?>
    </body>
</html>

But for variable must same with variable's string that's created, because if not same with variable string that's created first although that's type is same but has different of the format of variable like uppercase, etc., the variable can't be used Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        $color = "black";
        echo "My phone is . $color<br>";
        echo "My phone is . $Color<br>";
        echo "My phone is . $cOLOR<br>";
        ?>
    </body>
</html>

This example can't run because the variable of color has a three different variables.
