I'm testing a simple Web Service that sends and receives a string , but the server ( Apache 2 ) returns the following error message:
Fatal error: Uncaught SoapFault exception: [VersionMismatch] Wrong Version in /var/www/html/client.php:7 Stack trace: # 0 /var/www/html/client.php (7): SoapClient-> ; __ call ('helloName', Array) # 1 {main} thrown in /var/www/html/client.php on line 7
Below are the scripts:
Server application with PHP
<?php
function helloName($name)
{
return 'Hello ' . $name;
}
$WSDL = 'ws.asmx';
$server = new SoapServer($WSDL);
$server->addFunction('helloName');
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
$server->handle();
} else
{
foreach ($server->getFunctions() as $funcs) {
print $funcs . ' <br> ';
}
}
?>
