I am using SOAP to get data from some server (data coming in .xml) . But sometimes SOAP server is down and I need to display some error message instead of :
Warning: simplexml_load_string(): Entity: line 2: parser error : Start tag expected, '<' not found in /var/www/class/data2.php on line 619 Warning: simplexml_load_string(): in /var/www/class/data2.php on line 619 Warning: simplexml_load_string(): ^ in /var/www/class/data2.php
My code is:
$client = new SOAPClient ( 'link.wsdl' ); // initiate new SoapClient
$password ['_'] = 'PASSWORD'; // password for authenticate_user function in SoapHeader
$encoded = new SoapVar ( $password, SOAP_ENC_OBJECT ); // make SoapVariable out of $password
$header = new SoapHeader ( 'http://soapinterop.org/echoheader/', 'authenticate_user', $encoded ); // put authenticate_user method, and password in header
$client->__setSoapHeaders ( $header ); // set SoapHeader
$response = $client->get_details ($this->vin); // calling get_details with the vin given in the form field
$xml = simplexml_load_string ( $response ); // converting the response string to xml
$json = json_encode ( $xml ); // converting to an array in to easy steps (step 1)
$array = json_decode ( $json, TRUE ); // step 2
What I want: Replace Warning message with something like: "This service is temporary unavaliable"
After
$xml = simplexml_load_string ( $response );
check if
$xml === false
and set the error message accordingly
As you can read in manual the simplexml_load_string function:
Returns an object of class SimpleXMLElement with properties containing the data held within the xml document, or FALSE on failure.
So simply check if it fails and if it does echo your This service is temporary unavaliable
To get rid of this warning consider to ini_set('display_errors', '0'); on production
