# php-extension-check
Check your PHP project's PHP extension requirements against all loaded PHP extensions.

Requires a **PHP version** of **7.2** or above.

The idea behind this project is to have an idea of your project's requirements for a minimal server installation.

Another use case can be cleaning up old legacy projects using the same server configuration/installation for decades after doing some refactorings or upgrades, esp. when moving those projects into Docker images.

## Installation
*... todo, when any releases are ready*

## Usage
To check your code, simply run the `extension-check.phar`.

The tool automatically executes the checks for the current directory (`./`).

### Important
Please note that your command line and web server PHP configurations (php.ini files) may load different PHP extensions!

To use a specific `php.ini` file, run the tool like this:
```php
php -c path/to/your/webserver/php.ini ./extension-check.phar
```

### Checking a specific Directory
If you want to check a specific directory, you can specify it as an argument:
```php
./extension-check.phar ./src
```
Note: You should include your vendor files, if any, for valid results.

### Exclude Extensions
If you want to exclude some PHP extensions, you can use the `--exclude` option:
```php
./extension-check.phar --exclude=core,standard,xdebug
```
or alternatively
```php
./extension-check.phar --exclude=core --exclude=standard --exclude=xdebug
```
