I got hit with a noob mistake. :)
When the function was called more than once, it threw a function redeclare error of course. The
enviroment I was coding in never called it more than once but I caught it in testing and here is the
fully working revision. A simple logical step was all that was needed.
With PHP 5.3 still unstable for Debian Lenny at this time and not knowing if array_replace would
work with multi-dimensional arrays, I wrote my own. Since this site has helped me so much, I felt
the need to return the favor. :)
<?php
// Polecat's Multi-dimensional array_replace function
// Will take all data in second array and apply to first array leaving any non-corresponding
values untouched and intact
function polecat_array_replace( array &$array1, array &$array2 ) {
// This sub function is the iterator that will loop back on itself ad infinitum till it runs out
of array dimensions
if(!function_exists('tier_parse')){
function tier_parse(array &$t_array1, array&$t_array2) {
foreach ($t_array2 as $k2 => $v2) {
if (is_array($t_array2[$k2])) {
tier_parse($t_array1[$k2], $t_array2[$k2]);
} else {
$t_array1[$k2] = $t_array2[$k2];
}
}
return $t_array1;
}
}
foreach ($array2 as $key => $val) {
if (is_array($array2[$key])) {
tier_parse($array1[$key], $array2[$key]);
} else {
$array1[$key] = $array2[$key];
}
}
return $array1;
}
?>
