php soapclient call params

Question

I need to transform the above call in php and the particularity is that in the call it is mandatory to have three params in the same argument:

<v20:searchItem>
         <!--Optional:-->
         <arg0>customer_id</arg0>
         <arg1>table_name</arg1>
         <arg3><field_name>Barcode</field_name><value>record_id</value></arg3>
         <arg3><field_name>DOC_DATE min</field_name><value>date_min</value></arg3>
         <arg3><field_name>DOC_DATE max</field_name><value>date_max</value></arg3>
         <arg4></arg4>
         <arg5>0</arg5>
         <arg6>1000</arg6>
      </v20:searchItem>

My code is:

$myParams1 = array('field_name' => 'Barcode',
                                  'value' => $barcode);
$myParams2 = array('field_name' => 'DOC_DATE min',
                                  'value' => $datai);
$myParams3 = array('field_name' => 'DOC_DATE max',
                                  'value' => $newdate);
$params = array(
    "arg0" => $sasAliasSP,  
    "arg1" => $sasAliasDA,
    "arg2" => "",
    "arg3" =>$myParams1,
    "arg3" =>$myParams2,
    "arg3" =>$myParams3,
    "arg4" => "",
    "arg5" => "0",
    "arg6" => "1000"
);

but is not working, can you please help. Thank you

I finally found the solution in this post: https://stackoverflow.com/a/19774498/6564057

arg3 needs to be an array with ascending keys starting with 0, so my code now is:

$myParams[] = array('nome_Campo' => 'Barcode', 'valore' => $barcode);
$myParams[] = array('nome_Campo' => 'DOC_DATE min', 'valore' => $datai);
$myParams[] = array('nome_Campo' => 'DOC_DATE max', 'valore' => $newdate);

$params = array(
    "arg0" => $sasAliasSP,  
    "arg1" => $sasAliasDA,
    "arg2" => "",
    "arg3" => $myParams,
    "arg4" => "",
    "arg5" => "0",
    "arg6" => "1000"
);

and it works like charms. Thank you very much.
