In PHP, what are some best practices for efficiently searching and manipulating arrays, as demonstrated in the thread responses?

When searching and manipulating arrays in PHP, it is important to use built-in array functions efficiently to achieve optimal performance. Some best practices include using functions like array_search() for searching values in an array, array_filter() for filtering elements based on a callback function, and array_map() for applying a callback function to each element in the array. 

// Example of efficiently searching and manipulating arrays in PHP

// Searching for a value in an array
$fruits = ['apple', 'banana', 'orange'];
$index = array_search('banana', $fruits);
if ($index !== false) {
    echo 'Found at index: ' . $index;
}

// Filtering elements in an array
$numbers = [1, 2, 3, 4, 5];
$filtered = array_filter($numbers, function($num) {
    return $num % 2 == 0;
});
print_r($filtered);

// Manipulating elements in an array
$numbers = [1, 2, 3, 4, 5];
$squared = array_map(function($num) {
    return $num * $num;
}, $numbers);
print_r($squared);
