It’s possible to use PHP’s file_get_contents<\/a> to PUT JSON data to a RESTful webservice if you don’t want to use cURL.<\/p>\n

In this example I’m going to try to add or update a person using the NationBuilder API<\/a>.<\/p>\n

Firstly, we need the URL of the webservice, and the data you want to update as a JSON string.<\/p>\n

\r\n$access_token = 'set access token here';\r\n$nation = 'set nation name here';\r\n$url = \"https:\/\/$nation.nationbuilder.com\/api\/v1\/people\/push?access_token=$access_token\";\r\n\/\/ details we want to update\r\n$data = [\r\n    'person' => [\r\n        'email_opt_in' => true,\r\n        'do_not_contact' => false,\r\n        'do_not_call' => false,\r\n        'first_name' => 'Robert',\r\n        'last_name' => 'Price',\r\n        'email' => 'robert.price@email.adress',\r\n        'home_address' => [\r\n            'zip' => 'AB1 2CD'\r\n        ],\r\n        'bio' => 'Software developer - robertprice.co.uk'\r\n    ]\r\n];\r\n$json_data = json_encode($data);\r\n<\/pre>\n
Now we need to setup a stream_context so file_get_contents knows how to handle the request. <\/p>\n
Even though we’re PUTing data over HTTPS, we need to use the http context. We set method<\/code> to PUT<\/code<. Our headers in this case we need to set the Content-type<\/code> to application\/json<\/code>, Accept<\/code> to application\/json<\/code>, Connection<\/code> to close<\/code>, and Content-length<\/code> to the length of our JSON string. We’re PUTing this data over HTTP1.1 so we set the  to 1.1<\/code>. We’re sending the JSON in the body of the request, so we set this in the content<\/code>.<\/p>\n
As we are using HTTPS, we need to configure the ssl<\/code> settings. In this case I’m not going to verify the peer or the peer name.<\/p>\n
\r\n$context = stream_context_create([\r\n    'http' => [\r\n        'method' => 'PUT',\r\n        'header' => \"Content-type: application\/json\\r\\n\" .\r\n                    \"Accept: application\/json\\r\\n\" .\r\n                    \"Connection: close\\r\\n\" .\r\n                    \"Content-length: \" . strlen($json_data) . \"\\r\\n\",\r\n        'protocol_version' => 1.1,\r\n        'content' => $json_data\r\n    ],\r\n    'ssl' => [\r\n        'verify_peer' => false,\r\n        'verify_peer_name' => false\r\n    ]\r\n]);\r\n<\/pre>\n
Finally we PUT the data by calling file_get_contents. NationBuilder returns a JSON response to this call, so we can decode that and echo a confirmation message to the screen.<\/p>\n
\r\n$rawdata = file_get_contents($url, false, $context);\r\nif ($rawdata === false) {\r\n    exit(\"Unable to update data at $url\");\r\n}\r\n$data = json_decode($rawdata, true);\r\nif (JSON_ERROR_NONE !== json_last_error()) {\r\n    exit(\"Failed to parse json: \" . json_last_error_msg());\r\n}\r\necho \"Updated details for {$data['person']['first_name']} {$data['person']['last_name']}\\n\";\r\n<\/pre>\n
The full code for this, and some other examples of querying NationBuilder using PHP, can be found in my NationBuilder People In Nation – GitHub repository<\/a>.<\/p>\n
