Exporter
========
[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
This component provides the functionality to export PHP variables for visualization.
## Usage
Exporting:
```php
<?php
use SebastianBergmann\Exporter\Exporter;
$exporter = new Exporter;
/*
Exception Object &0000000078de0f0d000000002003a261 (
'message' => ''
'string' => ''
'code' => 0
'file' => '/home/sebastianbergmann/test.php'
'line' => 34
'trace' => Array &0 ()
'previous' => null
)
*/
print $exporter->export(new Exception);
```
## Data Types
Exporting simple types:
```php
<?php
use SebastianBergmann\Exporter\Exporter;
$exporter = new Exporter;
// 46
print $exporter->export(46);
// 4.0
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);
// resource(13) of type (stream)
print $exporter->export(fopen('php://stderr', 'w'));
// Binary String: 0x000102030405
print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
```
Exporting complex types:
```php
<?php
use SebastianBergmann\Exporter\Exporter;
$exporter = new Exporter;
/*
Array &0 (
0 => Array &1 (
0 => 1
1 => 2
2 => 3
)
1 => Array &2 (
0 => ''
1 => 0
2 => false
)
)
*/
print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
/*
Array &0 (
'self' => Array &1 (
'self' => Array &1
)
)
*/
$array = array();
$array['self'] = &$array;
print $exporter->export($array);
/*
stdClass Object &0000000003a66dcc0000000025e723e2 (
'self' => stdClass Object &0000000003a66dcc0000000025e723e2
)
*/
$obj = new stdClass();
$obj->self = $obj;
print $exporter->export($obj);
```
Compact exports:
```php
<?php
use SebastianBergmann\Exporter\Exporter;
$exporter = new Exporter;
// Array ()
print $exporter->shortenedExport(array());
// Array (...)
print $exporter->shortenedExport(array(1,2,3,4,5));
// stdClass Object ()
print $exporter->shortenedExport(new stdClass);
// Exception Object (...)
print $exporter->shortenedExport(new Exception);
// this\nis\na\nsuper\nlong\nstring\nt...\nspace
print $exporter->shortenedExport(
<<<LONG_STRING
this
is
a
super
long
string
that
wraps
a
lot
and
eats
up
a
lot
of
space
LONG_STRING
);
```
## 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
