PHP Code Indexer

A tool for indexing PHP code elements including functions, classes, methods, properties, parameters, PHPDoc annotations, attributes and their relative file paths to enable efficient searching using xpath.

Overview

The indexer performs the following steps:

1. Uses symfony/finder to locate PHP files
2. Detects which files have changed, been added or removed
3. Indexes the code elements in an XML data structure
4. Stores the index in an easily searchable XML file
5. Enables searching via XPath queries

Command line Usage

php index.php --out index.xml --include 'src/{*,**/*}.php' --include 'tests/{*,**/*}.php'

Explanation

Parameter	Short	Required	Description
--out <file>	-o <file>	Yes	Path to the output XML file for storing the index
--include <dir>	-i <file>	Yes	Directory to include for indexing; can be used multiple times
--exclude <pattern>	-e <file>	No	Glob pattern to exclude files or folders from the included directories
--working-directory <dir>	-w <file>	No	Sets the base directory for all relative paths

Notes:

• At least one --include is required.
• --exclude applies only within the scope of the specified --include paths.
• Patterns for --exclude support common glob syntax:
  • * matches any string.
  • xyz/*.* matches any file with an extension.
  • **/XyzTest.php matches directories recursively.
  • XyzTest.{php,inc} matches multiple file extensions.
  • src/{*,**/*}.php matches all .php files in the src directory and its subdirectories.
• If --working-directory is not set, the current working directory is used.

Usage Example

Find all attributes of class-methods with a specific name: //class/method/attribute[@name='NS\\MyAttribute']

First, index your PHP files:

use PhpLocate\UpdateIndexService;
use Psr\Log\NullLogger;
use Symfony\Component\Finder\Finder;

$files = (new Finder())
    ->in(__DIR__ . '/src')
    ->name('*.php');

$service = new UpdateIndexService(new NullLogger());
$service->updateIndex(indexPath: __DIR__ . '/index.xml', files: $files);

Then, search the index using XPath:

use PhpLocate\Index;

$index = Index::fromFile(__DIR__ . '/index.xml');
$path = $index->getFirstString("/files/file[class/method/attribute[@name='NS\\MyAttribute']]/@path");
echo $path;
