What are some best practices for sorting and iterating through arrays in PHP to avoid logic errors?

When sorting and iterating through arrays in PHP, it is important to use the appropriate sorting functions and loop structures to avoid logic errors. To ensure correct sorting, always use built-in PHP functions like `sort()` or `asort()` depending on whether you want to maintain the key-value association. When iterating through arrays, use `foreach` loops instead of `for` loops to avoid off-by-one errors and simplify the code. 

// Example of sorting and iterating through an array in PHP

// Sample array
$numbers = array(3, 1, 4, 1, 5, 9, 2, 6, 5);

// Sort the array in ascending order
sort($numbers);

// Iterate through the sorted array using foreach loop
foreach ($numbers as $number) {
    echo $number . ' ';
}
