Rob,
Thanks for your code example however having them as class properties
will not work. The main reason is that the default array is created
by reading a YAML file. The array is populated by reading a section
of a flat file and then it reads a section specific to the current
page (if any) and overrides the defaults. Here is the code I have
used to accomplish this.
Thanks to every who responded.
// parse through an array, $a is the original array and
// $b is the new array to merge into it
function override($a, $b)
{
// an array that will hold the new, properly
// merged version of the two arrays
$new = array();
// if we've encountered numbered keys, this
// will be true
$numbers = FALSE;
// if $a is bigger than $b, lots of code repetition
// beyond this point.. ugh.
if(count($a) >= count($b))
{
// override the arrays if necessary
foreach($a as $key => $val)
{
// if we've found a number, stop the loop
if(is_numeric($key)) // dunno why ctype_digit
didn't work...
{
$numbers = TRUE;
break;
}
// otherwise, override the key with a $b value
// if it exists.
else
$new[$key] = isset($b[$key]) ? $b[$key] :
$a[$key];
}
}
// otherwise..
else
{
// override the arrays if necessary
foreach($b as $key => $val)
{
if(is_numeric($key))
{
$numbers = TRUE;
break;
}
// otherwise, override the key with an $a value
// if it exists.
else
$new[$key] = isset($a[$key]) ? $a[$key] :
$b[$key];
}
}
// merge the arrays if they are numbered keys
if($numbers)
$new = array_merge($a, $b);
// loop through the new array and check for sub-arrays
foreach($new as $key => $val)
{
// recursively go through
if(is_array($new[$key]) && !$numbers)
$new[$key] = $this->override((isset($a[$key]) ?
$a[$key] :
array()), (isset($b[$key]) ? $b[$key] : array()));
}
// return the new, merged array
return $new;
}
