    **_I highly recommend you make a simple `test.php` file, put a `phpinfo();` statement in there, then copy the output and paste it into the [Xdebug installation wizard](https://xdebug.org/wizard.php). It will analyze it and give you tailored installation instructions for your environment._** In short:
 
-   - On Windows: [Download](https://xdebug.org/download.php) the appropiate precompiled DLL for your PHP version, architecture (64/32 Bit), thread safety (TS/NTS) and Visual Studio compiler version and place it in your PHP extension folder.

    - On Linux: Either download the source code as a tarball or [clone it with git](https://xdebug.org/docs/install#source), then [compile it](https://xdebug.org/docs/install#compile).
 
 2. [Configure PHP to use Xdebug](https://xdebug.org/docs/install#configure-php) by adding `zend_extension=path/to/xdebug` to your php.ini. The path of your php.ini is shown in your `phpinfo()` output under "Loaded Configuration File".

 - `ignore`: An optional array of glob patterns that errors should be ignored from (for example `**/vendor/**/*.php`)
 - `xdebugSettings`: Allows you to override XDebug's remote debugging settings to fine tuning XDebug to your needs. For example, you can play with `max_children` and `max_depth` to change the max number of array and object children that are retrieved and the max depth in structures like arrays and objects. This can speed up the debugger on slow machines.
