What are the best practices for formatting numerical data in PHP before sending it to an external system, such as an oven?

When sending numerical data from PHP to an external system, it is important to format the data correctly to ensure compatibility and accuracy. One common practice is to format the numerical data as a string with a specific number of decimal places before sending it. This can help prevent any rounding errors or data loss that may occur during transmission. Additionally, it is advisable to use PHP functions like number_format() to ensure the data is formatted correctly. 

// Format numerical data before sending to an external system
$number = 123.456789;
$formatted_number = number_format($number, 2); // Format the number to 2 decimal places

// Send the formatted number to the external system
// Code to send $formatted_number to the external system
