Access to undeclared static property php fatal error
<p>I am getting this error: <code>Access to undeclared static property: DBug::$errorMsg</code></p>

<p>Following is the code</p>

<pre><code>class DBug
{
    private static $errorMsg = array(
        1 =&gt; 'inv-req',
        2 =&gt; 'inv-reqPrm',
        3 =&gt; 'no-set',
        4 =&gt; 'less-h',
        5 =&gt; 'less-w'
    );

    public static function showTinyErrMsg($errCode=0) 
    {
        if(SHOW_ERROR_MSG_IN_RESPONSE === TRUE) {
            if(array_key_exists($errCode, self::$errorMsg)) {
            echo "// ".self::$errMsg[$errCode].";\n" ;
            }
        }
    }
}
</code></pre>

<p>I call this function by <code>DBug::showTinyErrMsg(1);</code>. I get the above mentioned error. I am surely missing some OO rule, please help me with this.</p>

<p>P.s: The reason for this class having all static member is, that it's a long standing class with all static members, so I had to add this new method as static</p>
