# 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 (;).

# Comments in PHP
|
|||
|
|
|
|||
|
|
PHP supports several ways of commenting:
|
|||
|
|
```

|||
|
|
|
|||
|
|
```

# 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):
|
|||
|
|
```
