PHP PLEASE! Thank you

1) Fahrenheit to Celsius conversion: You willneed to write a program that uses variables to store 4 values oftemperatures in Fahrenheit and then converts them todegrees Celsius. The formula for conversion is C=(F -32) * 5/9. The four values of temperature are a) 32 F, b) 100 F, c)0 F, d) -40 F. The output should print or echo the followingstatements identifying the writer of the program and the conversionfor each temperature value. Example: "This program wascreated by $Yourname. The temperature 32 degrees Fahrenheit isequivalent to 0 degrees Celsius". Use variables to storeyour name, the temperature values in Fahrenheit and temperaturevalues in Celsius.
