|  | # Основной синтаксис
 | |||
|  | 
 | |||
|  | Сценарий PHP можно разместить где угодно в документе. | |||
|  | 
 | |||
|  | Сценарий PHP начинается с `<?php` и заканчивается на `?>` | |||
|  | 
 | |||
|  | Ниже приведен пример простого PHP-файла с PHP-скриптом, который использует встроенную функцию PHP «echo» для вывода текста «Hello World!». на веб-странице | |||
|  | 
 | |||

|  | 
 | |||
|  | # Моя первая страница PHP
 | |||
|  | ``` | |||
|  | The output of that would be :  | |||
|  | ``` | |||
|  | 
 | |||
|  | Моя первая страница PHP | |||
|  | 
 | |||
|  | Привет, мир! | |||
|  | ``` | |||
|  | #### Note: PHP statements end with a semicolon (;).

|  | # PHP Case Sensitivity 
 | |||
|  |   | |||
|  |  In PHP, all keywords (eg if, else, while, echo, etc.), classes, functions, and user-defined functions are NOT case-sensitive.  | |||
|  |   | |||
|  |  In the example below, all three echo statements below are legal (and equal):  | |||
|  | ``` | |||
|  | 
 | |||
|  | ``` | |||
|  | ### However; all variable names are case-sensitive. 
 | |||
|  |   | |||
|  |  In the example below, only the first statement will display the value of the $color variable (this is because $color, $COLOR, and $coLOR are treated as three different variables):  | |||
|  | ``` | |||
