foreach array loop does not always work on Windows - php

Question

I encounter this very odd scenario. The PHP is below:
$complete_categories_list=array();
foreach ($modules_library_processed as $key=>$modules_categories_rendered) {
foreach ($modules_categories_rendered['modulecategories'] as $module_category_key=>$module_category_values) {
foreach ((array) $module_category_values as $module_key_inner=>$module_category_value) {
$complete_categories_list[]=trim($module_category_value);
}
}
}
This is working perfectly in Unix/Linux localhost and in some instances will work in Windows localhost. But not all of them. The problem is that at the end of the loop, $complete_categories_list is empty even though $modules_library_processed has some data on it. $modules_library_processed is a very large array, so I cannot post the entire data here. I hope someone can shed light on this.
UPDATE: The source is an XML file
simplexml_load_string($modules_xml_exported); which I converted to an array. The result is $modules_library_processed.
print_r($module_category_values) results to SimpleXMLElement Object ()
But I typecasted it to an array..so that should work right?

Answer 1

I think I have fixed the problem The root cause is the script processing SimpleXML which does not play when the script is run under Windows even though with all the Type casting, etc. I ended up rewriting my scripts so it won't output any SimpleXML element but all in array/string format. I hope this helps someone. Thanks.
