How can the use of arrays in PHP affect the performance of a website?

Using arrays in PHP can affect the performance of a website if the arrays are large and complex. This is because accessing and manipulating large arrays can consume a significant amount of memory and processing power. To improve performance, consider using more efficient data structures or optimizing the way arrays are used in your code. 

// Example of using a more efficient data structure, such as SplFixedArray
$fixedArray = new SplFixedArray(1000); // create a fixed-size array
$fixedArray[0] = 'value1';
$fixedArray[1] = 'value2';
// Accessing elements in a fixed-size array is faster than a regular PHP array

// Example of optimizing array usage
$largeArray = []; // create a regular PHP array
for ($i = 0; $i < 1000; $i++) {
    $largeArray[] = $i; // add elements to the array
}
// Instead of dynamically growing the array, pre-allocate its size for better performance
