如何将参数传递到在 python 中执行的 php 中？

import subprocessdef 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))

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