php-go

php-go is a simple interpreter written in Go, inspired by PHP syntax. The project aims to recreate a subset of PHP, allowing you to interpret and execute PHP-like code directly in Go. The interpreter is built using ANTLR to generate the necessary parsers for processing the code.

🚀 Features

Currently, php-go provides basic support for:

• Echo: Prints values, including strings, numbers, variables, and expressions.
• Operations: Performs arithmetic and comparison operations.
• Concatenation: Supports string concatenation using the . operator.
• Conditionals: Supports if-else statements with boolean expressions.
• Variables: Supports variables declarations.

🧑‍💻 How to Use

Prerequisites

• Go 1.x or higher installed.
• ANTLR installed for generating parsers. For more information, visit ANTLR's official website.

Execution Steps

1. Clone the repository:

   git clone https://github.com/xoesae/php-go.git
   cd php-go

2. Build the project: Run the following command to build the code:

   go build

3. Run the interpreter: After building, use the command below to run the PHP-like code from an input file:

   php-go path/to/file.php

   Example input:

   You can find several examples in the examples folder. You can run them using:

   php-go examples/echo.php

Code Examples

Here are some example inputs you can test, located in the examples folder:

// Example 1: Simple echo
echo "Hello, World!";

// Example 2: Variables
$name = "Carlos";
echo $name;

// Example 3: Arithmetic operations
echo 1 + 1;
echo 1.5 + 1;
echo 3+3==6;
echo 3+3==7;

// Example 4: String concatenation
echo "Carlos " . "Carlos";

// Example 5: Conditionals
if (true) { echo "TRUE"; } else { echo "FALSE"; }
if (false) { echo "TRUE"; } else { echo "FALSE"; }
