How to pass parameters into php executed in python?

Question content

I need to pass a parameter into php code executed in python

import subprocess
def php(code):
    p = subprocess.Popen(["php","-r", code],
                         stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    out = p.communicate() #returns a tuple (stdoutdata, stderrdata)
    if out[1] != b'': raise Exception(out[1].decode('UTF-8'))
    return out[0].decode('UTF-8')
val = str(1234)
code = """ \
function my_encoder($in){
    $out = base_convert($in,16,36);
return ($out);}

print(my_encoder('"""+{val}+"""'));
"""
print(php(code))

I don't know how to enter val as parameter of my_encoder function in php code.

Correct answer

If {, } is not part of python's f-string, do not use it because This results in invalid syntax. So just remove these curly braces:

print(my_encoder('"""+val+"""'));
"""
