How can PHP functions be used to replace commas with periods in numerical values for processing?

To replace commas with periods in numerical values for processing in PHP, you can use the str_replace() function. This function allows you to search for a specific character, such as a comma, and replace it with another character, such as a period. By using this function, you can easily convert numerical values with commas into a format that can be processed by PHP functions. 

// Sample numerical value with commas
$number = "1,234.56";

// Replace commas with periods
$number = str_replace(",", ".", $number);

// Output the modified numerical value
echo $number;
