使用具有复杂类型参数的PHP来使用SOAP Web服务

i am trying to consume a soap web service to send an array of complexType as a parameter using php function name Z_INTERFACE_IN looks like this:

<xsd:element name="Z_INTERFACE_IN">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="TAB_INT_IN" type="tns:ZTY_TAB_I_IN"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>

this function accepte as parameter an array of complexe type called ZTY_TAB_I_IN looks like this :

<xsd:complexType name="ZTY_TAB_I_IN">
<xsd:sequence>
<xsd:element name="item" type="tns:ZSI_IN" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>

the array also contains a list of complexType named ZSI_IN looks like

<xsd:complexType name="ZSI_IN">
<xsd:sequence>
<xsd:element name="MANDT" type="tns:clnt3"/>
<xsd:element name="TERID" type="tns:char4"/>
<xsd:element name="LDATE" type="tns:date10"/>
<xsd:element name="LTIME" type="tns:time"/>
<xsd:element name="ZAUSW" type="tns:char8"/>
<xsd:element name="PERNR" type="tns:char8"/>
<xsd:element name="USRUP" type="tns:char20"/>
</xsd:sequence>

there is an exemple that show how to send a single complexType as parameter using stdclass but not an array how can i send exemple like this

<urn:Z_INTERFACE_IN>
         <TAB_INT_IN>
            <!--Zero or more repetitions:-->
            <item>
               <MANDT>100</MANDT>
               <TERID>10</TERID>
               <LDATE>2019-05-16</LDATE>
               <LTIME>12:00:00</LTIME>
               <ZAUSW>test1</ZAUSW>
               <PERNR>test1</PERNR>
               <USRUP>test1</USRUP>
            </item>
         </TAB_INT_IN>
      </urn:Z_INTERFACE_IN>
