Update PHP scripts from their AST by using php-parser for reading and php-unparser for generating back the php.
You must include the module to your script and feed to it a php file string.
var fs = require('fs'); // Load the writer var writer = require('php-writer'); // Read file content var contents = fs.readFileSync('my-php-file.php', 'utf8'); // All the possible options var options = { writer: { indent: true, dontUseWhitespaces: false, shortArray: true, forceNamespaceBrackets: false }, parser: { debug: false, locations: false, extractDoc: false, suppressErrors: false }, lexer: { all_tokens: false, comment_tokens: false, mode_eval: false, asp_tags: false, short_tags: false }, ast: { withPositions: true } }; // Init the writer var myPhpFile = new writer(contents, options); // Print the file AST object console.log(myPhpFile);You can pass to the writer an options object to customize your writer instance:
- writer: The same options you would pass to php-unparser
- parser: The same options you would pass to php-parser
- ast: The same options you would pass to php-parser
If you want to learn more about AST you can read the definitions.
All the examples assume that you have already loaded the file like in the example.
var myPhpFile = new writer(contents, options); myPhpFile.findFunction('foo').setCode('return $a + $b');var myPhpFile = new writer(contents, options); myPhpFile.findClass('Foo_Class').setProperty('bar', 'foo-bar');
