# PHP On the Go (`pogo`)

Pogo allows you to write small PHP scripts which use PHP libraries (courtesy

of `composer`/`packagist`)...  but it *doesn't* require you setup a

special-purpose folder, project, or repository.  To use a dependency, simply

add a small pragma into your script. For example:

```php

#!require symfony/yaml: ~4.4

```

This makes it easier to use PHP libraries for glue-scripts, throw-away scripts, quick experiments, etc.

## Example

Let's pick a small task that requires a few libraries -- suppose we want

to generate a pretty PDF from a source-code file (`*.php`, `*.json`, etc).

We'll need a pretty-printer ([scrivo/highlight.php](https://github.com/scrivo/highlight.php))

and a PDF generator ([dompdf/dompdf](https://github.com/dompdf/dompdf)).

Skimming the README for each library, one finds a few introductory snippets.

I took these, added the `#!require` pragmas, and improvised a little on the

`$html` variable. This becomes a small script, `code2pdf.php`:

```php

setAutodetectLanguages(['php', 'css', 'yaml', 'json', 'js']);

$highlighted = $hl->highlightAuto($code);

$html = sprintf('', \HighlightUtilities\getStyleSheetPath('sunburst.css'));

$html .= sprintf("
%s
", $highlighted->language, $highlighted->value);


#!require dompdf/dompdf: ~0.8.3

$dompdf = new \Dompdf\Dompdf();

$dompdf->loadHtml($html);

$dompdf->setPaper('A4', 'landscape');

$dompdf->render();

$dompdf->stream();

```

To run this script in the CLI, just use:

```bash

pogo code2pdf.php

```

Of course, this script expects some content as input (e.g. `myfile.yml`) and produces a PDF as output (e.g. `myfile.pdf`), so a more realistic command would be

```bash

cat myfile.yml | pogo code2pdf.php > myfile.pdf

```

That's it!

## More examples

The [examples](./examples) folder has several examples of using other libraries and frameworks, such as [ReactPHP](examples/httpd-react.php), [Symfony Console](examples/cli-symfony.php), [Clippy](examples/cli-clippy.php), and [Robo](examples/cli-robo.php). Each example is an executable program.

## Motivation

Most of my day-to-day work is in PHP, JS, and bash.  From time-to-time, one needs a bit of glue-code for one-offs, and

I find myself avoiding PHP for that task...  because using a library in PHP still requires bits of administrativa.

`pogo` is an experiment to reduce that administrativa.  Just create a `.php` file and run it.
