Execute php code in Python

Example code:

import subprocess

# if the script don't need output.
subprocess.call("php /path/to/your/script.php")

# if you want output
proc = subprocess.Popen("php /path/to/your/script.php", shell=True, stdout=subprocess.PIPE)
script_response = proc.stdout.read()

Using PDO prepared statements:

$placeholders = str_repeat('?, ', count($array)-1) . '?';
$stmt = $pdo->prepare("SELECT * FROM table WHERE field IN ($placeholders)");
$stmt->execute($array);

$placeholders will contain a sequence of ?, ?, ? placeholders, with the same number of ? as the size of the array. Then when you execute the statement, the array values are bound to the placeholders.

Needless to say you should find another solution ASAP. In the meantime you can eval the code like this:

$str = '<h1>Welcome</h1><?php echo $motto?><br/>'; // Your DB content

eval("?> $str <?php ");

I can't stress that enough: eval is dangerous, and application code shouldn't be in the database. Try a template parser like Smarty, Dwoo, or my favorite: Twig.
