Pest is a PHP client library for RESTful web services.
Unlike Zend_Rest_Client, which is not really a "REST" client at all (more like RPC-over-HTTP), Pest supports the four REST verbs (GET/POST/PUT/DELETE) and pays attention to HTTP response status codes.
To install Pest, use the following composer require statement:
{
"require": {
"educoder/pest": "1.0.0"
}
}
Pest's get/post/put/delete() return the raw response body as a string. See the info on PestXML (below) if you're working with XML-based REST services and PestJSON if you're working with JSON.
<?php
$pest = new Pest('http://example.com');
$thing = $pest->get('/things');
$thing = $pest->post('/things',
array(
'name' => "Foo",
'colour' => "Red"
)
);
$thing = $pest->put('/things/15',
array(
'colour' => "Blue"
)
);
$pest->delete('/things/15');
?>
Responses with error status codes (4xx and 5xx) raise exceptions.
<?php
try {
$thing = $pest->get('/things/18');
} catch (Pest_NotFound $e) {
// 404
echo "Thing with ID 18 doesn't exist!";
}
try {
$thing = $pest->post('/things', array('colour' => "Red"));
} catch (Pest_InvalidRecord $e) {
// 422
echo "Data for Thing is invalid because: ".$e->getMessage();
}
?>
PestXML is an XML-centric version of Pest, specifically targeted at REST services that return XML data. Rather than returning the raw response body as a string, PestXML will try to parse the service's response into a SimpleXML object.
<?php
$pest = new Pest('http://example.com');
$things = $pest->get('/things.xml');
$colours = $things->xpath('//colour');
foreach($colours as $colour) {
echo $colour."\n";
}
?>
Similarly, PestJSON is a JSON-centric version of Pest.
