initializing a private array in a class in php

Question

yes...im creating a class where i want to use a predefined (ie const) array as a private class member yet php isn't loading the array ie when i try the array_flip in constructor its telling $fieldnamemap is empty.

class RETS_translate {

      // hold the datebase connection that gets passed in constructor
      private $dbConn;

      // IMPORTANT! this is the bridge between old system and new system...handle with care
      private $fieldNameMap = array(

        "StreetNumber" => "street_number",

        private $fieldNameMapFlip;                                   

      function __construct($inDb=NULL) {

        // store db connection for later use...
        $this->dbConn = $db;

        $fieldNameMapFlip = array_flip($fieldNameMap);

      }  // end constructor 

    }

Since it's part of the class you need to access the array using $this. Change

$fieldNameMapFlip = array_flip($fieldNameMap);

to

$fieldNameMapFlip = array_flip($this->fieldNameMap);
