# sebastian/exporter
|
|
|
|
This component provides the functionality to export PHP variables for visualization.
|
|
|
|
## Installation
|
|
|
|
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
|
|
|
|
```
|
|
composer require sebastian/exporter
|
|
```
|
|
|
|
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
|
|
|
|
```
|
|
composer require --dev sebastian/exporter
|
|
```
|
|
|
|

|
print $exporter->export(4.0);
|
|
|
|
// 'hello, world!'
|
|
print $exporter->export('hello, world!');
|
|
|
|
// false
|
|
print $exporter->export(false);
|
|
|
|
// NAN

|
print $exporter->export(acos(8));
|
|
|
|
// -INF

|
print $exporter->export(log(0));
|
|
|
|
// null
|
|
print $exporter->export(null);
|

|
|
*/
|
|
|
|
print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
|
|
|
|
/*

*/
|
|
|
|
$array = array();
|
|
$array['self'] = &$array;
|
|
print $exporter->export($array);
|
|
|
|
/*

print $exporter->shortenedExport(new Exception);
|
|
|
|
// this\nis\na\nsuper\nlong\nstring\nt...\nspace
