What are some common issues with decimal input handling in PHP forms, especially when dealing with different decimal separators like commas and periods?

When dealing with decimal input handling in PHP forms, a common issue arises when users from different regions use different decimal separators like commas and periods. To solve this issue, you can normalize the input by replacing any commas with periods before processing the data. 

// Normalize decimal input by replacing commas with periods
$decimalInput = str_replace(',', '.', $_POST['decimal_input']);

// Process the normalized decimal input
// For example, you can convert it to a float for calculations
$normalizedDecimal = (float) $decimalInput;

// Use $normalizedDecimal in your calculations or database operations
