What are some best practices for optimizing memory usage and script performance when working with large and dynamic data structures like Techtrees in PHP applications, especially in the context of browser games?

When working with large and dynamic data structures like Techtrees in PHP applications for browser games, it is important to optimize memory usage and script performance. One way to achieve this is by using efficient data structures and algorithms, avoiding unnecessary memory allocations, and optimizing loops and conditionals. 

// Example of optimizing memory usage and script performance when working with large and dynamic data structures like Techtrees in PHP applications

// Use efficient data structures like arrays or objects
$techTree = [
    'tech1' => [
        'name' => 'Technology 1',
        'cost' => 100,
        'requirements' => ['tech2']
    ],
    'tech2' => [
        'name' => 'Technology 2',
        'cost' => 150,
        'requirements' => []
    ]
];

// Avoid unnecessary memory allocations
foreach ($techTree as $tech) {
    // Process tech data
}

// Optimize loops and conditionals
foreach ($techTree as $tech) {
    if ($tech['cost'] > 0) {
        // Process tech data
    }
}
