Passing 'string' value to Python Scripts

Hi, I'm looking for a way to pass the string value to my Python Script. My Python script looks like this,

Code:

name = raw_input("Enter your name: ")
print name

And my PHP code is like this:

PHP Code:


		
			
<?php 

echo "HelloPython!!";

$output = null;

exec('python HelloPython.py', $output, $return);

print_r($output);

print_r($return);

?>





<form action="test.php" method="post">

Query Name: <input type ="text" name="Qname">



<input type="submit" value="Confirm">

</form>

What I want to do is I want to enter my name from my PHP page and send that name value to Python script which is 'name'= raw_input("Enter your name here:").
Can somebody please help me find out how can I do this, thank you so much.

You need to feed something to stdin but exec() won't let you do that. proc_open will.

Untested.

PHP Code:


		
			
 $input = "HelloPython!!"; // you might need a newline



$desc = array(

    0 => array("pipe", "r"),

    1 => array("pipe", "w"),

    2 => STDOUT

);

$pipes = array();

$p = proc_open("python HelloPython.py", $desc, $pipes);

if ($p) {

    fwrite($pipes[0], $input);

    fclose($pipes[0]);

    $output = stream_get_contents($pipes[1]);

    fclose($pipes[1]);



    print_r($output);

    proc_close($p);

} else {

    echo "Could not run script";

}

Thank you for your reply. I dunno why but it doesn't work somehow. I've seen many tutorials like this too, but i still don't understand quite well.

I'm not sure but I checked $p like this:

PHP Code:


		
			
<?php 



$input = "My name"; 



$desc = array( 

    0 => array("pipe", "r"), 

    1 => array("pipe", "w"), 

    2 => STDOUT 

); 

$pipes = array(); 

$p = proc_open("python HelloPython.py", $desc, $pipes); 

echo "It's here";

if ($p) { 

    echo "OK"; 

} else { 

    echo "Could not run script"; 

}  

?>

I still got the same result "Could not run script", so maybe something is not right on "$p", but I'm not sure now what is it
