or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.

You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# php-cpg
A (Bytecode) CPG creator for PHP

# Status
![Scala CI](https://github.com/simkoc/php-cpg/workflows/Scala%20CI/badge.svg)

# Dependencies

- [patched](https://github.com/simkoc/php-src) PHP
- PHP 7.4.27 from branch [`PHP-7.4.27`](https://github.com/simkoc/php-src/tree/PHP-7.4.27)
- PHP 8.2.2 from branch [`PHP-8.2.2`](https://github.com/simkoc/php-src/tree/PHP-8.2.2)
- we recommend to build them locally for dev purposes
- consider using the Dockerfiles in resources/docker for productive use
- sbt
- scala
- php-parse (only for the source code layer)

# Building and Running

## Dependencies

You need to download and install our [patched](https://github.com/simkoc/php-src/) PHP versions.

Create the `main.conf` by using the main.conf.default and adjust the parameters according to your system.

## Building the project
The project can be build and run with the subsequent steps, yet it will only work with the `bytecode` argument. The source code support relies on `php-parse`, you can find the install instructions in the sub section `Source code support`.
```
sbt stage
./php2cpg -h
no more arguments and a subaction has still to be chosen
usage: PHP Cpg Creator [rootFolder] {-c,-o,-e,-h,-f,-s,-l,-v} log-evaluation bytecode
create a cpg from PHP
[rootFolder] the root folder of the project
-c/--config <value> the config file to use (def:./main.conf)
-o/--output <value> the destination file into which to store the cpg (def:<config>)
-e/--endings <value> the file endings included for analysis (def:<config>)
-h/--help prints this help message
-f/--forced when set files are simply overwritten
-s/--strictParsing if set each project file has to be parsed successfully
-l/--permissiveLinking linking strategy for call graph set to permissive
-v/--verbose output some progress indicators
log-evaluation
bytecode create a bytecode CPG
```

## Source code support
Source code is analyzed using `php-parse`. The following install steps are taken from the official install instructions: https://getcomposer.org/download/.
```
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '795f976fe0ebd8b75f26a6dd68f78fd3453ce79f32ecb33e7fd087d39bfeb978342fb73ac986cd4f54edd0dc902601dc') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
# Location is expected by php2cpg
mkdir -p $HOME/.config/composer/vendor/ && COMPOSER_VENDOR_DIR=$HOME/.config/composer/vendor/ php composer.phar require nikic/php-parser
```


# Documentation

[Opcodes](./documentation/README.md)

# Using Docker

Build the image
```
docker build -t phpcpg /your/path/to/php-cpg/ --build-arg GH_TOKEN=<your token>
```

Run the image
```
➜ ~ docker run -it phpcpg /bin/bash
root@f43557f5be46:/php-cpg# ./php2cpg
The first parameter has to be <sourcecode|bytecode> to determine which cpg layer to create
usage:
./php2cpg sourcecode main.php
./php2cpg bytecode main.php
```

## Token

Create the github token at https://github.com/settings/tokens. The token needs to have `repo` permissions.
