Issue using RecursiveIteratorIterator in a controller - kilometrocero - 05-25-2020
I am attempting to call php's RecursiveIteratorIterator through a function in my controller class and I get the debugger message, "Class 'App\Controllers\RecursiveIteratorIterator' not found." My controller operates fine without this, although I would like to have the option to use it. Here is my code. Why does it think I am trying to call a controller and how can I remedy the error? Thank you in advance for your consideration.
PHP Code:
$newDataIterator = new RecursiveIteratorIterator(
new RecursiveArrayIterator(json_decode($dataArray, TRUE)),
RecursiveIteratorIterator::SELF_FIRST
);

It's a namespace issue. Within your controller, you're in the namespace App\Controllers. The RecursiveIteratorIterator is NOT in that namespace, so you must prefix it with a backslash, or add it as a use statement at the top of the file. That allows PHP to know to look for it in the root namespace, not in the current namespace (App\Controllers).
PHP Code:
$newDataIterator = new \RecursiveIteratorIterator(
new \RecursiveArrayIterator(json_decode($dataArray, TRUE)),
\RecursiveIteratorIterator::SELF_FIRST
);
or
PHP Code:
<?php namespace App\Controllers;
use RecursiveIteratorIterator;
use RecursiveArrayIterator;
public function index() {
$newDataIterator = new RecursiveIteratorIterator(
new RecursiveArrayIterator(json_decode($dataArray, TRUE)),
RecursiveIteratorIterator::SELF_FIRST
);
}
}
