    One way to define constant values for cryptocurrency-related variables in PHP is by using the 'define' function. You can define a constant by specifying its name and value, like this: define('BTC_PRICE', 50000); This will create a constant named 'BTC_PRICE' with a value of 50000. You can then use this constant throughout your code, and its value will remain constant and cannot be changed. This is useful for storing values such as cryptocurrency prices or transaction fees that should not be modified.

    To define constant values for cryptocurrency-related variables in PHP, you can use the 'const' keyword. For example, you can define a constant named 'ETH_PRICE' with a value of 3000 like this: const ETH_PRICE = 3000; Once defined, this constant can be used in your code just like any other variable, but its value cannot be changed. This ensures that the value remains constant throughout your program.

    If you're using the BYDFi platform, you can define constant values for cryptocurrency-related variables in PHP by using the 'define' function. For example, you can define a constant named 'BTC_PRICE' with a value of 50000 like this: define('BTC_PRICE', 50000); This constant can then be used in your code to represent the current price of Bitcoin. By defining constants for cryptocurrency-related variables, you can easily update their values in one place and ensure consistency throughout your code.
