Are foreach loops generally faster than for loops in PHP when processing data?

Foreach loops are generally slower than for loops in PHP when processing data, as foreach loops involve more overhead due to their internal implementation. If performance is a concern, using a for loop may be more efficient, especially when dealing with large datasets. 

// Example of using a for loop instead of a foreach loop for processing data
$data = [1, 2, 3, 4, 5];

for($i = 0; $i < count($data); $i++) {
    // Process each element in the array
    echo $data[$i] . "\n";
}
