<?php

$first_id = 110;

$items = [
  [
    'id' => 101,
    'content' => 'Test 1'
  ],
  [
    'id' => 110,
    'content' => 'Test 2'
  ],
  [
    'id' => 120,
    'content' => 'Test 3'

];

$_items = [];

foreach( $items as $index => $item ) {
  $item['order'] = 0;
  
  if ($item['id'] === $first_id) {
    $item['order'] = 0; // Sort to first
  }
  
  if ($index === 2) {
    $item['order'] = 2; // Sort to last
  }
  
  $_items[] = $item;
}

// PHP 7.4
usort($items, fn($a, $b) => $a['order'] <=> $b['order']);

// Result: 110, 101, 125, 120
