An extension to eval python codes in PHP
- pybind11 V2.1.1
- PHP-CPP-LEGACY V1.5.7 / PHP-CPP V2.x
- PHP 5 / PHP 7
- Python 3
- C++ 11
$code = <<<EOD
a = [1, 2, 3]
EOD;
$python = new Python();
$python->eval($code);
var_export($python->extract("a"));... you can use extract method in php to get that python variable, codes above output:
array (
0 => 1,
1 => 2,
2 => 3,
)
$a = ["a" => "b", "c" => "d"];
$code = <<<EOD
print(a)
EOD;
$python = new Python();
$python->assign("a", $a);
$python->eval($code);... you can use assign method in php to let python know that php variable, codes above output:
{'a': 'b', 'c': 'd'}
$a = ["a" => "b", "c" => "d"];
$code = <<<EOD
def dofunc(arg1, arg2):
print("Python Output")
print(arg1)
print(arg2)
return {"Python": {"a": arg1, "b": arg2}}
after = "abcd"
EOD;
$python = new Python();
$python->eval($code);
$python->assign("tmp", $a);
var_dump("PHP Here...", $python->dofunc($a, "py::tmp"));... you can call functions defined in Python as-is-a $python->method(), codes above output:
Python Output
{'a': 'b', 'c': 'd'}
{'a': 'b', 'c': 'd'}
string(11) "PHP Here..."
array(1) {
'Python' =>
array(2) {
'a' =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
'b' =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
}
}
Here, We can also use these ways to call functions defined in Python:
var_dump("PHP Here...", $python->call("dofunc", [$a, "py::tmp"]));
var_dump("PHP Here...", $python->call("dofunc(after, tmp)"));this will output:
Python Output
{'a': 'b', 'c': 'd'} // $a in php
{'a': 'b', 'c': 'd'} // tmp in python which assigned by php
string(11) "PHP Here..."
array(1) {
'Python' =>
array(2) {
'a' =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
'b' =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
}
}
Python Output
abcd // after in python
{'a': 'b', 'c': 'd'} // tmp in python which assigned by php
string(11) "PHP Here..."
array(1) {
'Python' =>
array(2) {
'a' =>
string(4) "abcd"
'b' =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
}
}
$code = <<<EOD
tmp = {'a': 'b', 'c': 'd'}
print("Python begin")
print(dofunc(tmp))
print("Python end")
EOD;
$python = new Python();
$python->def("dofunc", function($param) {
echo __function__ . " in PHP: Get params from Python :" . PHP_EOL;
echo var_export($param, true) . PHP_EOL;
return [
"php" => $param
];
});
$python->eval($code);... you can call php funciton in python as-is-a real python function, codes above output:
Python begin
{closure} in PHP: Get params from Python :
array (
0 =>
array (
'a' => 'b',
'c' => 'd',
),
)
{'php': [{'a': 'b', 'c': 'd'}]}
Python end
if you like, you can also call that function using the php way, like this:
var_dump($python->dofunc("py::tmp", "phpString"));this will output:
{closure} in PHP: Get params from Python :
array (
0 =>
array (
'a' => 'b',
'c' => 'd',
),
1 => 'phpString',
)
array(1) {
'php' =>
array(2) {
[0] =>
array(2) {
'a' =>
string(1) "b"
'c' =>
string(1) "d"
}
[1] =>
string(9) "phpString"
}
}
