从Python中运行PHP脚本 - 将值从Python传递给PHP

SOLVED: Solution ------------------------------------------------------------------

I would like to execute the function getimagesize() from the PHP standard library in a Python script. The function must be passed an image path from Python.

I know how to run a php script in Python, but I can't figure out how to pass an argument from Python -> PHP and then get the result back into Python.

Here is what I have in the Python Script:

def php_script_runner(script_path):
    p = subprocess.Popen(['php', script_path], stdout=subprocess.PIPE)
    result = p.communicate()[0]
    return result

Here is what I have in the PHP file (I am not sure how to pass an argument to it):

<?php getimagesize() ?>

How would I pass an argument to 'get_image_size.php' and have it return the result in Python for further processing?

I would like to further implement this idea for other custom PHP functions. The main goal of this question is not only to find the size of an image, but to be able to use this for other functions in the future that are php intensive.

The main goal of this is to determine:

1. How to call a PHP script in Python
2. How to send an agrument to a PHP script from Python
3. How to parse the output of the PHP script back into Python

Solved by doing this: Python:

import subprocess
import json
import sys
import os

def php(script_path, argument):
    p = subprocess.Popen(['php', script_path, argument], stdout=subprocess.PIPE)
    result = p.communicate()[0]
    return result

image_dimensions_json =str(php("get_image_size.php", image_location_relative[1:]))
dic = json.loads(image_dimensions_json)
print str(dic["0"]) + "|" + str(dic["1"])

The reason for the [1:] is because for some reason the "/" in the path causes an error. I found removing it fixed the issue.

PHP:

<?php

echo(json_encode(getimagesize($argv[1])));

?>

echo or print_r work. I found it easy to convert the array to JSON, as Python has a json decoder built into the standard library.

Hope this helps people! I plan on using this conecpt to implement much larger PHP functions.

If I where you, I'd echo the Python result out as a JSON (or possibly XML) object and then reread that information with the PHP script. If at all possible I'd highly recommend separating these two languages into two separate webpages and maybe even get the Python to return the data via a GET style query to the page, aka API style.

What's wrong with using the Python Image Library, PIL ?

from PIL import Image
im=Image.open(filepath)
print im.size # (height,width) tuple

Invoking a PHP script to get the image dimensions, is just plain wrong. I can't really think of anything that PHP does better than Python, that it justifies firing up an instance of both runtimes :)

My advice: Stick with one language at a time, and learn the standard library of Python :) You shouldn't be having trouble doing something in Python if you can do it in PHP.
