How to pass variables to PHP script & return values from PHP script using Python?

I have a Python script called “cal.py” & PHP script called DBfun.php which contains DB calls.

In my DBfun.php script,I have function called
function get_sby_name($f_haddress,$f_sdesc)
and I need to pass below #1 & #2 variables to this PHP script and take DB results to Python script and print.

I tried below #3 code part,but cannot pass variables to PHP function from python script.
If there is any way to do this ?

Python Script: cal.py

f_haddress=10.228.86.74 #1
f_sdesc='GR1-SW' #2
f_notify_type=''

#I tried this code part in Pyton file  #3
#import subprocess #3
#proc = subprocess.Popen("php /path/to/src/DBfun.php", shell=True, stdout=subprocess.PIPE) #3
#script_response = proc.stdout.read() #3


if(f_notify_type=="PROBLEM"):
  f_color="#FF0000"
  f_adesc="Status:OK"

else:
  f_color="#AEB6BF"
  f_adesc="Status:Warning"

print(f_color+''+f_adesc)
