Trying simple insert but nothing is added to the trie object

[rvencu]

`$trie = new Trie; $rtrie = new Trie;

	$wordCount = 0;
	foreach ( $wordData as $word ) {
		if ( $word > '' ) {
			$trie->insert( $word );
			$rtrie->insert( strrev( $word ) );
			++ $wordCount;
		}
	}`

I have a collection of 38000 items (composed of one or more words) that I am trying to add to trie but nothing happens with the above code

I also tried this variation $trie[$word] = $word

but in this case, the page returns error 503 (server too busy)

both versions are NOT producing any PHP error inside the error log
