Bug description: provide a function to get caller scope variables
Description:
------------
Provide a function to get variables from caller scope.
I knew ticket 47454, 40339, 34210 are similar,
but this is indeed a useful function that was overlooked.
Reproduce code:
---------------
Currently:
$name="myname";
$value="lk,jdsk'jlkjdf";
function safe($sql)
{$sql=strtr($sql, array('"'=>'\"', '\\'=>'\\\\'));
return 'return "'.preg_replace(array('/\{#(.*?)\}/'),
array('".addslashes($\1)."'), $sql).'";';
}
$sql="insert into z_test (name, value) values ('{$name}', '{#value}')";
mysql_query(eval(safe($sql)));
If we have function get_caller_vars() in caller's scope:
(similar to get_defined_vars() in current scope)
$name="myname";
$value="lk,jdsk'jlkjdf";
function mysql_query_safe($sql)
{extract(get_caller_vars());
$sql=strtr($sql, array('"'=>'\"', '\\'=>'\\\\'));
return 'return "'.preg_replace(array('/\{#(.*?)\}/'),
array('".addslashes($\1)."'), $sql).'";';
$sql=eval($sql);
mysql_query($sql);
}
$sql="insert into z_test (name, value) values ('{$name}', '{#value}')";
mysql_query_safe($sql);
Expected result:
----------------
We have a function to get variables in caller scope.
Actual result:
--------------
No such function.
