异常的参数错误（[string $ exception [，long $ code]]）

Question

Have been staring to this exception for while and have no clue whats going wrong.

Fatal Error: Wrong parameters for Exception([string $exception [, long $code ]])

It seems pretty straight forward, the Exception expects a message and a optional code, though for some reason the code won't agree with me. Even when I drop the last parameter $e (for keeping the stacktrace), this same error pops up.

try {
    // ...
} catch (Exception $e) {
    throw new Exception('Client cannot be created', 0, $e);
}

Only when i omit both the code ( 0 ) and the previous exception ( $e ), the error is thrown correctly.

try {
    // ...
} catch (Exception $e) {
    throw new Exception('Client cannot be created');
}

Although i never worked with SOAP technology, so just taken from SoapClient manual

The exceptions option is a boolean value defining whether soap errors throw exceptions of type SoapFault

and soapFault syntax is

SoapFault::SoapFault ( string $faultcode , 
                       string $faultstring [, 
                       string $faultactor [, 
                       string $detail [, 
                       string $faultname [, 
                       string $headerfault ]]]] );

so I will suggest you to check all the examples on manual. here i got one exmaple

To get custom Soap Error Codes use in the catch $e->faultcode instead of $e->getCode .

<?php 
try { 
    // ... 
} catch (SoapFault $e) { 
    echo $e->faultcode; 
} 
?>

one more example:

try { 
            $options = array( 
                'soap_version'=>SOAP_1_1, 
                'exceptions'=>true, 
                'trace'=>1, 
                'cache_wsdl'=>WSDL_CACHE_NONE 
            ); 
            $client = new SoapClient('http://www.example.com/end_point.wsdl', $options); 

        } catch (Exception $e) { 
            echo "<h2>Exception Error!</h2>"; 
            echo $e->getMessage(); 
        } 

Hope it helps.
