php - 如何编写whmcs内连接 'where condition'

Question

whmcs内连接'where条件'，

两个表都有相同的字段。

如何区分where条件下的表名？

尝试过这个，

$table = "tblclients";
$fields = "id,firstname,lastname,domain";
$where = array(
   "lastname"=>array("sqltype"=>"LIKE","value"=>"Demo"),
   "companyname"=>array("sqltype"=>"NEQ","value"=>""),
);
$sort = "id";
$sortorder = "ASC";
$limits = "0,5";
$join = "tblhosting ON tblhosting.userid=tblclients.id";
$result = select_query($table,$fields,$where,$sort,$sortorder,$limits,$join);

如何在where条件下指定表名？

Answer 1

$where = array(
   "table1.lastname"=>array("sqltype"=>"LIKE","value"=>"Demo"),
   "table2.companyname"=>array("sqltype"=>"NEQ","value"=>""),
);
