How can PHP documentation be utilized to troubleshoot issues with formatting numeric values?

When troubleshooting formatting issues with numeric values in PHP, the PHP documentation can be utilized to find the appropriate functions and methods to correctly format the values. One common issue is displaying numeric values with specific decimal precision or adding commas for thousands separators. By referencing the PHP documentation for number formatting functions like number_format(), sprintf(), or round(), developers can easily implement the necessary formatting rules.

// Example of formatting a numeric value with two decimal places and adding a thousands separator
$number = 1234567.89;
$formatted_number = number_format($number, 2, '.', ',');
echo $formatted_number; // Output: 1,234,567.89
