问题
Im pulling info from Jira Atlassian API, ive worked with other code and it works fine and i change it to json and all the info gets returned as an object.
However in this case i get this server error: PHP Catchable fatal error: Object of class stdClass could not be converted to string in /usr/local/vhosts/999/webspace/httpdocs/mysite/filters1.php on line 411
Now here is the code im trying to run:
$username = 'xxx@gmail.com';
$password = 'xxxxxxx';
$url = 'xxx.atlassian.net/rest/api/2/search?jql=project+%3D+bug+AND+component+%3D+%22issues%22+AND+status+in+(Open,+Reopened)';
$headers = array(
'Accept: application/json',
'Content-Type: application/json'
);
$ch = curl_init();
$test = "This is the content of the custom field.";
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
//curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
$result = curl_exec($ch);
$issue_json = json_decode($result);
$ch_error = curl_error($ch);
if ($ch_error) {
echo "cURL Error: $ch_error";
} else {
echo $issue_json;
}
curl_close($ch);
As i mentioned that returns the error above but if i alter the code to
$result = curl_exec($ch);
//$issue_json = json_decode($result);
and then i echo out $result it works and returns everything i need but as a huge string and not an object like i want. I formatted the whole string below so its a bit more readable. I googled some similar issues and i think i need to do something like this:
foreach($string as $strings)
{
echo $strings;
}
But i not too familiar with this kind of stuff just basic php so im a bit lost

回答1:
The function json_decode does not return a string.
Have a look at the documentation for the function.
http://fr2.php.net/function.json-decode.php
The problem is that you're trying to echo the object. The following code is faulty.
echo $issue_json;
You can use var_dump to see the structure of the object returned from json_decode.
var_dump($issue_json);
回答2:
To answer the question title, if your object does not have a __string method using it as a string will throw an exception. (I think this changed in 5.2), so to do unexploding string conversion on the hop you need:
if (is_object($arg)) {
$arg = method_exists($arg, '__toString') ? (string)$arg : 'Object';
}
