What are some best practices for writing efficient and error-free PHP code when using loops like for loops?

When using for loops in PHP, it is important to initialize loop variables properly, set the correct condition for the loop to continue, and increment or decrement the loop variable inside the loop. Additionally, make sure to handle edge cases such as empty arrays or ensuring that the loop variable stays within the bounds of the array. 

// Example of a correct implementation of a for loop in PHP
$array = [1, 2, 3, 4, 5];
$array_length = count($array);

for ($i = 0; $i < $array_length; $i++) {
    echo $array[$i] . " ";
}
