I have an array where I store key-value pair only when the value is not null. I'd like to know how to retrieve keys in the array?
<?php
$pArray = Array();
if(!is_null($params['Name']))
$pArray["Name"] = $params['Name'];
if(!is_null($params['Age']))
$pArray["Age"] = $params['Age'];
if(!is_null($params['Salary']))
$pArray["Salary"] = $params['Salary'];
if(count($pArray) > 0)
{
//Loop through the array and get the key on by one ...
}
?>
Thanks for helping
