# ANTLR4 Runtime for PHP
|
||||
|
||||
### First steps
|
||||
|
||||
#### 1. Install ANTLR4
|
||||
|
||||
[The getting started guide](https://github.com/antlr/antlr4/blob/master/doc/getting-started.md)
|
||||
should get you started.
|
||||
|
||||
#### 2. Install the PHP ANTLR runtime
|
||||
|
||||
Each target language for ANTLR has a runtime package for running parser
|
||||
generated by ANTLR4. The runtime provides a common set of tools for using your parser.
|
||||
|
||||
Install the runtime with Composer:
|
||||
|
||||
```bash
|
||||
composer install antlr/antlr4
|
||||
```
|
||||
|
||||
#### 3. Generate your parser
|
||||
|
||||
You use the ANTLR4 "tool" to generate a parser. These will reference the ANTLR
|
||||
runtime, installed above.
|
||||
|
||||
Suppose you're using a UNIX system and have set up an alias for the ANTLR4 tool
|
||||
as described in [the getting started guide](https://github.com/antlr/antlr4/blob/master/doc/getting-started.md).
|
||||
To generate your PHP parser, run the following command:
|
||||
|
||||
```bash
|
||||
antlr4 -Dlanguage=PHP MyGrammar.g4
|
||||
```
|
||||
|
||||
For a full list of antlr4 tool options, please visit the
|
||||
[tool documentation page](https://github.com/antlr/antlr4/blob/master/doc/tool-options.md).
|
||||
|
||||
### Complete example
|
||||
|
||||
Suppose you're using the JSON grammar from https://github.com/antlr/grammars-v4/tree/master/json.
|
||||
|
||||
Then, invoke `antlr4 -Dlanguage=PHP JSON.g4`. The result of this is a
|
||||
collection of `.php` files in the `parser` directory including:
|
||||
```
|
||||
JsonParser.php
|
||||
JsonBaseListener.php
|
||||
JsonLexer.php
|
||||
JsonListener.php
|
||||
```
|
||||
|
||||
Another common option to the ANTLR tool is `-visitor`, which generates a parse
|
||||
tree visitor, but we won't be doing that here. For a full list of antlr4 tool
|
||||
options, please visit the [tool documentation page](tool-options.md).
|
||||
|
||||
We'll write a small main func to call the generated parser/lexer
|
||||
(assuming they are separate). This one writes out the encountered
|
||||
`ParseTreeContext`'s:
|
||||
|
||||
```php
|
||||
<?php
|
||||
|
||||
namespace JsonParser;
|
||||
|
||||
use Antlr\Antlr4\Runtime\CommonTokenStream;
|
||||
use Antlr\Antlr4\Runtime\Error\Listeners\DiagnosticErrorListener;
|
||||
use Antlr\Antlr4\Runtime\InputStream;
|
||||
use Antlr\Antlr4\Runtime\ParserRuleContext;
|
||||
use Antlr\Antlr4\Runtime\Tree\ErrorNode;
|
||||
use Antlr\Antlr4\Runtime\Tree\ParseTreeListener;
|
||||
use Antlr\Antlr4\Runtime\Tree\ParseTreeWalker;
|
||||
use Antlr\Antlr4\Runtime\Tree\TerminalNode;
|
||||
|
||||
final class TreeShapeListener implements ParseTreeListener {
|
||||
public function visitTerminal(TerminalNode $node) : void {}
|
||||
public function visitErrorNode(ErrorNode $node) : void {}
|
||||
public function exitEveryRule(ParserRuleContext $ctx) : void {}
|
||||
|
||||
public function enterEveryRule(ParserRuleContext $ctx) : void {
|
||||
echo $ctx->getText();
|
||||
}
|
||||
}
|
||||
|
||||
$input = InputStream::fromPath($argv[1]);
|
||||
$lexer = new JSONLexer($input);
|
||||
$tokens = new CommonTokenStream($lexer);
|
||||
$parser = new JSONParser($tokens);
|
||||
$parser->addErrorListener(new DiagnosticErrorListener());
|
||||
$parser->setBuildParseTree(true);
|
||||
$tree = $parser->json();
|
||||
|
||||
ParseTreeWalker::default()->walk(new TreeShapeListener(), $tree);
|
||||
```
|
||||
|
||||
Create a `example.json` file:
|
||||
```json
|
||||
{"a":1}
|
||||
```
|
||||
|
||||
Parse the input file:
|
||||
|
||||
```
|
||||
php json.php example.json
|
||||
```
|
||||
|
||||
The expected output is:
|
||||
|
||||
```
|
||||
{"a":1}
|
||||
{"a":1}
|
||||
"a":1
|
||||
1
|
||||
```

## Target feature parity
|
||||
|
||||
New features generally appear in the Java target and then migrate to the other targets, but these other targets don't always get updated in the same overall tool release. This section tries to identify features added to Java that have not been added to the other targets.
