What are some best practices for handling complex variable naming in PHP loops?

When handling complex variable naming in PHP loops, it is best practice to use descriptive and meaningful variable names to improve code readability and maintainability. Avoid using single-letter variable names or cryptic abbreviations that may be confusing to other developers or your future self. Instead, opt for clear and concise names that accurately reflect the purpose of the variable within the loop. 

// Bad example: using single-letter variable names
for ($i = 0; $i < count($array); $i++) {
    $val = $array[$i];
    // do something with $val
}

// Good example: using descriptive variable names
foreach ($items as $item) {
    $itemValue = $item->getValue();
    // do something with $itemValue
}
