Convert array and object with HTML entities - php

Question

I am trying to write a piece of code, that will recursively convert every string in an array or object to be safe with the quotes for displaying in input boxes.
This is an array I wrote, with parts I have seen from other peoples. And it works for objects but not arrays, it seems to get to the second array, and outputs a string "null"
function fixQuotes($item)
{
if (is_object($item)) {
foreach (get_object_vars($item) as $property => $value) {
//If item is an object, then run recursively
if (is_array($value) || is_object($value)) {
fixQuotes($value);
} else {
$item->$property = htmlentities($value, ENT_QUOTES);
}
}
return $item;
} elseif (is_array($item)) {
foreach ($item as $property => $value) {
//If item is an array, then run recursively
if (is_array($value) || is_object($value)) {
fixQuotes($value);
} else {
$item[$property] = htmlentities((string)$value, ENT_QUOTES);
}
}
}
}

It was not saving the array if it was two arrays deep, it is now working, also it was missing the return on the array. Thanks for reading it.
Here is a copy of the fixed code if someone in future needs a script that does this.
function fixQuotes($item)
{
if (is_object($item)) {
foreach (get_object_vars($item) as $property => $value) {
//If item is an object, then run recursively
if (is_array($value) || is_object($value)) {
$item->$property = fixQuotes($value);
} else {
$item->$property = htmlentities($value, ENT_QUOTES);
}
}
return $item;
} elseif (is_array($item)) {
foreach ($item as $property => $value) {
//If item is an array, then run recursively
if (is_array($value) || is_object($value)) {
$item[$property] = fixQuotes($value);
} else {
$item[$property] = htmlentities((string)$value, ENT_QUOTES);
}
}
return $item;
}
}
