在php中执行python - 瀚海星空

2011-08-25

美国人Jon写了个PiP，Python in Php项目，可以实现在php中调用python。Jon 79年出生在新泽西州，毕业于罗切斯特理工，曾于2002年合写 Professional PHP4 Programming 示例：

1. Evaluating Python Code from PHP

Result
test 1 50 60.4
test 2.208 test

2. Python Object Instantiation
# module.py
class TestClass:
    def __init__(self, foo):
        self.foo = foo

    def returnInt(self):
        return 1113

    def test(self, a, b = 'str'):
        return "a = %d, b = %s" % (a, b)

    def returnMe(self):
        return self

    def returnTuple(self):
        return (1, "two", 3.0)

    def returnList(self):
        return [1, "two", 3.0]

    def returnDict(self):
        d = {}
        d['one'] = 1
        d['two'] = 2
        d['three'] = 3
        return d

    def p(self, var):
        print var
returnInt() . "n";
print $p->test(1, 'bar') . "n";

print $p->foo . "n";
$p->foo = 987;
print $p->foo . "n";

# $copy points to the same object
$copy = $p->returnMe();
print $copy->foo . "n";
$p->foo = 987;
print $copy->foo . "n";
?>
Result
1113
a = 1, b = bar
435
987
987
987

3. Type Conversion
returnTuple());
var_dump($p->returnList());
var_dump($p->returnDict());

$a = array('one' => 1, 2, 3);
$p->p($a);

class Test {
    var $member = 'test';
}

$t = new Test();
$p->p($t);
?>
Result
array(3) {
  [0]=>
  int(1)
  [1]=>
  string(3) "two"
  [2]=>
  float(3)
}
array(3) {
  [0]=>
  int(1)
  [1]=>
  string(3) "two"
  [2]=>
  float(3)
}
array(3) {
  ["three"]=>
  int(3)
  ["two"]=>
  int(2)
  ["one"]=>
  int(1)
}
{'1': 3, '0': 2, 'one': 1}
{'member': 'test'}

不过，如果不采用PiP这样的方式，也可以考虑用php的system()和popen(),proc_open()来调用。如果要执行用户脚本，一定要注意安全。可以用escapeshellarg（）和escapeshellcmd（）或类似preg_replace(‘/[^a-zA-Z0-9]/’, ‘’, $str)去掉无关字符。
