Why Is My PHP SoapClient Returning Empty? Enable the SOAP Extension to Fix It

In a PHP script that uses SoapClient, the call to the remote method returns an empty result, as shown by the following code snippet:

// ...省略部分代码...
$reversed = $client->call('query', array($params1));
$result = $reversed['queryresult'];
echo json_encode($result);
// ...省略部分代码...

The problem is usually caused by the SOAP extension not being loaded in the PHP runtime.

Solution

Check that the soap extension is enabled in the PHP configuration. If it is missing, enable it by editing the php.ini file. extension=soap Follow these steps to enable the extension:

Open the php.ini configuration file.

Search for the line extension=soap and remove the leading semicolon ( ;) to uncomment it.

Save the file and restart the PHP service (or the web server) to apply the changes.

After restarting, the SoapClient call should return the expected data instead of an empty response.
