Array_reverse() in PHP3

[Anon]

I need to read an associated array in reverse order, but don't have access to the PHP4 function Array_reverse() as my provider only runs PHP3.

I need to do this to write a series of linked records to a database. The links are undetermined from the start, I just have a sequence in the array. In order to avoid making a cumbersome previous/next household, I just want write them in reverse order using the mysql_insert_id() to obtain, what will be the 'next' field for the next record--which actually is the previous record... if I can just read them in reverse order.

I use while and each() to traverse the array, but other suggestions are welcome.

for (end($array_name); $key = key($array_name); prev($array_name) ) {
$value = $array_name[$key];
}

That for loop will start at the end of your array and populate the $key variable with the key name of each element moving backwards. Then using that $key value pull the value of the array field and put it into the variable $value.

as a function:

function array_reverse($array){
for (end($array); $key = key($array); prev($array) ) {
$reverse_array[] = $array[$key];
}
$reverse_array[] = $array[$key];
return $reverse_array;
}
