PHP - Need Help Accessing Array Variable After Iteration

<?php

require 'vendor/autoload.php';

$client = new Elasticsearch/Client();

$root = realpath('~/elkdata/for_elk_test_2014_11_24/Agencies');

$iter = new RecursiveIteratorIterator(
		new RecursiveDirectoryIterator($root, RecursiveDirectoryIterator::SKIP_DOTS),
		RecursiveIteratorIterator::SELF_FIRST,
		RecursiveIteratorIterator::CATCH_GET_CHILD);
		
$paths = array($root);
foreach ($iter as $path => $dir) {
	if ($dir -> isDir()) {
		$paths[] = $path;
		}
	}

//Create the index and mappings
$mapping['index'] = 'rvuehistoricaldocuments2009-2013'; //mapping code
$mapping['body'] = array (
	'mappings' => array (
		'documents' => array (
			'_source' => array (
				'enabled' => true
			),
			'properties' => array(
				'doc_name' => array(
					'type' => 'string',
					'analyzer' => 'standard'
				),
				'description' => array(
					'type' => 'string'
				)
			)
		)
	)
);

$client ->indices()->create($mapping)


//Now index the documents

for ($i = 0; $i <= count($paths); $i++) {
	$params ['body'][] = array(
		'index' => array(
		'type' => 'documents'
		'body' => array(
			'foo' => 'bar' //Document body goes here
			
			)
		)
	);
	
	//Every 1000 documents stop and send the bulk request.
	
	if($1 % 1000) {
		$responses = $client->bulk($params);
	
	// erase the old bulk request
	$params = array();
	
	// unset the bulk response when you are done to save memory
	unset($responses);
	}
}
?>

So I have a very simple for loop that I am populating a list with levels and exp required to achieve the next level. I have been using a sandbox to test my output and have also created an excel sheet to replicate the data to verify the content. This code was not mine from the beginning and in creating the spreadsheet I discovered the flaw. Below is the code I am trying to fix:

function experience($L, $pres = 0) {
    $a = 0;
    $end = 0;
	for ($x = 1; $x < $L; ++$x) {
        $a += $x * round($x + 5 * pow(4, ($x / 300)));
	}
	if ($x > 199) {
		$a += $x * round($x + 7 * pow(4, ($x / 290)));
	}
	if ($x > 399) {
		$a += $x * round($x + 11 * pow(4, ($x / 280)));
	}
	if ($x > 599) {
		$a += $x * round($x + 19 * pow(4, ($x / 270)));
	}
	if ($x > 799) {
		$a += $x * round($x + 35 * pow(4, ($x / 260)));
	}
	if ($x > 999) {
		$a += $x * round($x + 67 * pow(4, ($x / 250)));
	}
	return round($a / 1.25);
}

Below is the troubleshooting I am attempting to do (Modified and simplified for and while loop):

//for loop
$no = 200;
$a = 0;
for ($x = 1; $x < $no; ++$x) {
    $a += $x + 1;
}
if ($no > 199) {
    $a += $x + 2;
}
echo $a;


//while loop
$no = 200;
$a = 0;
$x = 1;
while (($x - 1) < $no) {
    $a += $x * round($x + 5 * pow(4, ($x / 300)));
    $x++;
    if ($x > 199) {
        $a += $x * round($x + 7 * pow(4, ($x / 290)));
    }
}
echo $a;

Upon request I can also provide snipets of the excel sheet. So the gist of what the issue I am having is this. Between level 199 and 200 the iteration of the loop is running one extra time through the initial formula. As you can tell at level 200, 400, 600, 800 and 1000 I want this formula to change so that it simplifies the amount of exp required to achieve the next level. I can not for the life of me figure out how to restrict the loop while still allowing the values 200 up to run through it for the first 199 iterations.

The output I should get from the primary code for levels 199 through 201 are as follows: 199 =  200 =  201 = 

At level 199 I am good but for whatever reason it runs one additional iteration at the level 1-199 formula and then moves on to the 200 level formula messing up the values.

Any and all help is much appreciated. I am a novice hobbyist at best and have been doing this for many, many years now but sometimes I get stumped. I chalk it up to lack of proper training and time to really be serious with it.

Thanks in advance....NICON

Hey, im struggeling with a small piece of code....

Thats my code:

Global $user_ID;
$user_ID = get_current_user_id();

   echo"User number $user_ID is loggedin";

Echo gives me this:
"User number 2 is loggedin"

Now i want to add it to my array:
 

$atts['href'] .=  $user_ID . 'abc';

'href' is set to "https://test.com/"

What im getting now ist

https://test.com/abc

Can someone tell my why the '2' is missing??
