Description:

Very simple logic. Here you go;


Reproduce code:

if($_GET['param']=='') $_GET['param'] = "I am changed forever.";
echo "Should print: " . $_GET['param'] . "<br>\n";

import_request_variables("g", "g_");
echo "And... !: " . $g_param . "<br>\n";


Expected result:
----------------
Should print: I am changed forever.
And... !: I am changed forever.

Should print: I am changed forever.
And... !:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Only the actual values supplied via GPC can be imported.

I am sorry to re-open this bug but it is very very similar to this one.

Reproduce code:
---------------
foreach($_POST as $key => $value) {
  $_POST[$key] = trim($value);
  $_POST[$key] = strip_tags($value);
  $_POST[$key] = mysql_real_escape_string($value);
}


Expected result:
----------------
The code above should; trim, strip_tags and mysql_real_escape_string to the original values but it only applies the last function in foreach, which is mysql_real_escape_string.

When i replace the trim() line to the end, it only trims and so on..

I think same goes for _GET and _COOKIE values as well.

I am terribly sorry.

Since the $value contains original, this was such an amateurish bug report.
