## Installation

10 
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
11 
 
12 
```
13 
composer require sebastian/exporter
14 
```
15 
 
16 
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:
17 
 
18 
```
19 
composer require --dev sebastian/exporter
20 
```

Exporting simple types:
49 
 
50 
```php
51 
<?php
52 
use SebastianBergmann\Exporter\Exporter;
53 
 
54 
$exporter = new Exporter;
55 
 
56 
// 46
57 
print $exporter->export(46);
58 
 
59 
// 4.0
60 
print $exporter->export(4.0);
61 
 
62 
// 'hello, world!'
63 
print $exporter->export('hello, world!');
64 
 
65 
// false
66 
print $exporter->export(false);
67 
 
68 
// NAN
69 
print $exporter->export(acos(8));
70 
 
71 
// -INF
72 
print $exporter->export(log(0));
73 
 
74 
// null
75 
print $exporter->export(null);
76 
 
77 
// resource(13) of type (stream)
78 
print $exporter->export(fopen('php://stderr', 'w'));
79 
 
80 
// Binary String: 0x000102030405
81 
print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
82 
```
83 
 
84 
Exporting complex types:
85 
 
86 
```php
87 
<?php
88 
use SebastianBergmann\Exporter\Exporter;
89 
 
90 
$exporter = new Exporter;
91 
 
92 
/*
93 
Array &0 (
94 
 
95 
 
96 
        1 => 2
97 
        2 => 3
98 
    )
99 
    1 => Array &2 (
100 
 
101 
        1 => 0
102 
        2 => false
103 
    )
104 
)
105 
*/
106 
 
107 
print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
108 
 
109 
/*
110 
Array &0 (
111 
    'self' => Array &1 (
112 
        'self' => Array &1
113 
    )
114 
)
115 
*/
116 
 
117 
$array = array();
118 
$array['self'] = &$array;
119 
print $exporter->export($array);
120 
 
121 
/*
122 
stdClass Object &0000000003a66dcc0000000025e723e2 (
123 
    'self' => stdClass Object &0000000003a66dcc0000000025e723e2
124 
)
125 
*/
126 
 
127 
$obj = new stdClass();
128 
$obj->self = $obj;
129 
print $exporter->export($obj);
130 
```
131 
 
132 
Compact exports:
133 
 
134 
```php
135 
<?php
136 
use SebastianBergmann\Exporter\Exporter;
137 
 
138 
$exporter = new Exporter;
139 
 
140 
// Array ()
141 
print $exporter->shortenedExport(array());
142 
 
143 
// Array (...)
144 
print $exporter->shortenedExport(array(1,2,3,4,5));
145 
 
146 
// stdClass Object ()
147 
print $exporter->shortenedExport(new stdClass);
148 
 
149 
// Exception Object (...)
150 
print $exporter->shortenedExport(new Exception);
151 
 
152 
// this\nis\na\nsuper\nlong\nstring\nt...\nspace
153 
print $exporter->shortenedExport(
154 
<<<LONG_STRING
155 
this
