    Here are some key aspects and solutions for PHP code formatting:

    1. Indentation: Use consistent indentation to denote the structure of your code. The common practice is to use either 4 spaces or a tab per indentation level. For example:

      if ($condition) {
          // code to execute if the condition is true
      } else {
          // code to execute if the condition is false
      }
      
    2. Line Length: Try to keep your lines of code not too long. A common standard is to limit lines to 80-120 characters.

    3. Brace Style: There are various brace styles, like K&R (1TBS), Allman, etc. Choose one and stick to it. For example, the K&R style looks like this:

      if ($condition) {
          // code
      } else {
          // code
      }
      
    4. Naming Conventions: Use clear and descriptive names for variables, functions, and classes. Standard practices include camelCase for variables and functions, and PascalCase for classes.

    5. Commenting and Documentation: Write comments and documentation where necessary to explain complex logic or important decisions in your code.

    6. Consistent Use of Quotes: Be consistent in your use of single or double quotes. Typically, single quotes are used for strings that do not require parsing of variables, and double quotes are used otherwise.

    7. Avoid Deep Nesting: Too many levels of nesting can make the code harder to read and maintain.

    8. Use Linters and Formatters: Tools like PHP_CodeSniffer, PHP-CS-Fixer, or Prettier for PHP can automatically format your code according to specified guidelines.

    9. Follow Established Coding Standards: Adhere to widely accepted standards like the PSR-1 and PSR-2 coding standards proposed by the PHP Framework Interop Group (FIG).

    Here's a small example demonstrating some of these practices:

    // Example of well-formatted PHP code
    function calculateSum($numbers) {
        $sum = 0;
        foreach ($numbers as $number) {
            $sum += $number;
        }
        return $sum;
    }
    
    $numbersArray = [1, 2, 3, 4, 5];
    $total = calculateSum($numbersArray);
    echo "Total Sum: " . $total;
    

    In this example, the code follows consistent indentation, uses camelCase for function and variable names, adheres to a limit on line length, and employs comments for clarity.
