E_ERROR in SoapClient

[Paulo Azevedo]

Is there a way to prevent the E_ERROR when SoapClient is not able to load a
WSDL file?

I just want to handle the error gracefully.

Thanks.

Yes. See http://php.net/manual/en/soapclient.soapclient.php

My problem is that SoapClient triggers a E_ERROR ( Fatal Error ) instead of
throwing an Exception.
Since E_ERROR cannot be catchable I don't find a way to gracefully handly
this problem.

PHP Fatal error:  SOAP-ERROR: Encoding: object hasn't 'profileData' property


Is there any way to gracefully catch this error?

You can tell the SoapClient to generate exceptions rather than errors.

[1] "The exceptions option is a boolean value defining whether soap
errors throw exceptions of type SoapFault."

<?php
try
        {
        $client=new SoapClient('http://api.rkd.reuters.com/schemas/wsdl/Charts_1_HttpAndRKDToken.wsdl',
array('exceptions' => True));
        }
catch(Exception $exception)
        {
        echo $exception;
        }
echo 'Finished';


outputs ...

However, that doesn't happen if the WSDL cannot be loaded at all IIRC  
(e.g. on a 404).

Thanks for your answer.
Your code is complaining about loading the extension, not the WSDL file.

I've tried this code:
$client = new SoapClient( "http://127.0.0.1/nonexiting.wsdl",
    array(
        'exceptions' => true,
        'trace'    => true,
        'cache_wsdl' => WSDL_CACHE_NONE
    )
);

and it gives the error:
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't load from '
http://127.0.0.1/nonexiting.wsdl' : failed to load external entity "
http://127.0.0.1/nonexiting.wsdl"

As far as i know the 'exceptions' => true is set by default but it only
works for SoapFault exceptions.

Really?

Look at my code ...

<?php
try
        {
// $client=new
SoapClient('http://api.rkd.reuters.com/schemas/wsdl/Charts_1_HttpAndRKDToken.wsdl',
array('exceptions' => True));
        $client = new SoapClient( "http://127.0.0.1/nonexiting.wsdl",
array('exceptions' => True));
        }
catch(Exception $exception)
        {
        echo $exception;
        }
echo PHP_EOL, PHP_EOL, "Look I finished the program and didn't crash!";
?>

See the message at the end?

I run this and get output of ...

===============
SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load
from 'http://127.0.0.1/nonexiting.wsdl' : failed to load external
entity "http://127.0.0.1/nonexiting.wsdl"
 in Z:\soapbad.php:5
Stack trace:
#0 Z:\soapbad.php(5): SoapClient->SoapClient('http://127.0.0....', Array)
#1 {main}

Look I finished the program and didn't crash!
=================


If you are getting the SOAPclient to throw an exception, you would
normally be expected to catch it.

Other wise you end up with an uncaught exception. I use a global
handler for these so I can be lazy.

My catch() clause could just as easily have been ...

echo "We didn't get what we wanted.", PHP_EOL;

I'm sorry, but your code doesn't work for me, heres a dump of what I did:

*[pazevedo@scmat116 html]$ cat t.php*
<?php
try {
    $client = new SoapClient( "http://127.0.0.1/nonexiting.wsdl",
        array('exceptions' => True)
    );
} catch( Exception $exception ) {
    echo $exception;
}
echo PHP_EOL, PHP_EOL, "Look I finished the program and didn't crash!";
?>
*[pazevedo@scmat116 html]$ php t.php*
PHP Fatal error:  SOAP-ERROR: Parsing WSDL: Couldn't load from '
http://127.0.0.1/nonexiting.wsdl' : failed to load external entity "
http://127.0.0.1/nonexiting.wsdl"
 in /var/www/html/t.php on line 11

Do you use any special/specific configuration on your php.ini ?

I tried this on PHP 5.2.10 on Windows and Linux.
