关于通过引用传递值:
function test_reference_in(&$array) {
$array['a'] = 2;
}
$test_array['a'] = 1;
test_reference_in($test_array);
echo $test_array; //-> it prints 2
关于nusoap:
现在在nusoap 中,客户端类是nusoap_client。
在该课程中,您有nusoap_client::call() 拨打肥皂电话。
这就是nusoap_client::call() 中出现的数组$params 中的内容,在您的示例中就是您的$sendParams。
我将省略与$params 无关的所有其余方法,以更好地解释发生了什么。
/**
* Pseudocode of call to explain the operations on $params
* @see nusoap_client::call()
*/
function call($operation,$params=array(),$namespace='http://tempuri.org',$soapAction='',$headers=false,$rpcParams=null,$style='rpc',$use='encoded'){
/*
some code
.
.
.
*/
// varDump is just var_dump so print $params
$this->appendDebug('params=' . $this->varDump($params));
/*
some code
.
.
.
*/
/*
* Here $params has been read, no write operation in there
* about serializeRPCParameters @see class.wsdl.php again is just reading
*/
if (is_string($params)) {
$this->debug("serializing param string for WSDL operation $operation");
$payload = $params;
} elseif (is_array($params)) {
$this->debug("serializing param array for WSDL operation $operation");
$payload = $this->wsdl->serializeRPCParameters($operation,'input',$params,$this->bindingType);
} else {
$this->debug('params must be array or string');
$this->setError('params must be array or string');
return false;
}
/*
* Here again $params has been read, no write operation in there
*/
if (is_string($params)) {
$this->debug("serializing param string for operation $operation");
$payload = $params;
} elseif (is_array($params)) {
$this->debug("serializing param array for operation $operation");
foreach($params as $k => $v){
$payload .= $this->serialize_val($v,$k,false,false,false,false,$use);
}
} else {
$this->debug('params must be array or string');
$this->setError('params must be array or string');
return false;
}
}
因此,正如您在此处看到的,通过引用传递 $params 没有任何优势。
因为:
- $params 在 nusoap_client::call() 中没有以任何方式修改
- 即使您在必须再次使用 nusoap_client::call() 之后在其他地方修改 $params
如果你想通过引用传递 $params 怎么办?我可以吗?
是的,你可以!
要实现这一点,您必须复制 nusoap_client.php 并将其命名为 nusoap_client_new.php。
在那里将类名形式nusoap_client修改为nusoap_client_new。
// From this
class nusoap_client extends nusoap_base {
// To this
class nusoap_client_new extends nusoap_base {
修改nusoap_client_new::call() 方法,在参数中添加ref,如下所示:
/*
* Please note &$params=array() instead of $params=array()
*/
function call($operation,&$params = array(),$namespace='http://tempuri.org',$soapAction='',$headers=false,$rpcParams=null,$style='rpc',$use='encoded'){
/**
* Of course here you have to modify your code to make some operation on $params
* according to your needs.
*/
/*
original code
.
.
.
*/
}
最后更新您的代码以要求并使用nusoap_client_new::call() 而不是nusoap_client::call()。
