I'm attempting too fetch and parse JSON in PHP via curl. I am unable to parse the response, and see it dumping to my screen instead. Here is sample code.
<?php
$url = 'XXXXXXXXXXXXXXXXXXXXX';
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HTTPGET, true);
curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
'X-Mashape-Key: XXXXXXXXXXXXXXXXXXXXXXXXX',
'Accept: application/json'
));
$result = curl_exec($cURL); ## this seems to be the line printing the response?
curl_close($cURL);
echo "<br />--------------------------------------------------------<br />";
var_dump($cURL);
echo "<br />--------------------------------------------------------<br />";
var_dump($result);
echo "<br />--------------------------------------------------------<br />";
$json = json_decode($result);
echo "<br />--------------------------------------------------------<br />";
print_r($json);
echo "<br />--------------------------------------------------------<br />";
echo $json->word;
echo $json->definitions[0]->definition;
echo "<br />--------------------------------------------------------<br />";
?>
And the output is:
{"word":"incredible","definitions":[{"definition":"beyond belief or understanding","partOfSpeech":"adjective"}]}
--------------------------------------------------------
resource(2) of type (Unknown)
--------------------------------------------------------
bool(true)
--------------------------------------------------------
--------------------------------------------------------
1
--------------------------------------------------------
--------------------------------------------------------
See how my JSON is appearing on screen before my first echo statement? Why is this happening?
cURL doesn't return transfer but it outputs. You must not output your transfer. Add CURLOPT_RETURNTRANSFER option with true value. Also in the response JSON, definitions is not an object it's array and it will be parsed as array in php too. Also there is no attachments key in response so you can't access it.
$url = 'XXXXXXXXXXXXXXXXXXXXX';
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HTTPGET, true);
curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
'X-Mashape-Key: XXXXXXXXXXXXXXXXXXXXXXXXX',
'Accept: application/json'
));
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1); // add this line to catch your response with curl_exec function.
$result = curl_exec($cURL);
$json = json_decode($result);
print_r($json); // this will print parsed json.
echo $json->word;
echo $json->definitions[0]->definition; // Get First Entry of definitions
Use $json = json_decode($json); and then u can use $json['word'] and so on.
