OK, let's open "modules/Top/index.php" and now will find code line like:
| Code: |
$result9 = sql_query("SELECT pollID, pollTitle, timeStamp, voters FROM ".$prefix."_poll_desc $querylang order by voters DESC limit 0,$top", $dbi);
|
And just add "p" char to "$querylang" so it will be "$queryplang".
Final result:
| Code: |
$result9 = sql_query("SELECT pollID, pollTitle, timeStamp, voters FROM ".$prefix."_poll_desc $queryplang order by voters DESC limit 0,$top", $dbi);
|
That's all. Enjoy and have a nice day  |

I use very simple handmade php script, which will read in php script file, then searches for all variables and finally lists them all with frequency of using. Result is something like:
$mid --> 12 times
$buf --> 39 times
$restr --> 1 times
It is primitive utility, but helpful. |

It is written for private use and therefore the code is a mess 
Try to write something similar, this is simple. |

As i said before, code is a mess, because it was meant for private use.
But here it is:
| Code: |
<?php
if(empty($_REQUEST['file']))
{
?>
<HTML>
<HEAD>
<TITLE>Select file to analyze...</TITLE>
</HEAD>
<BODY>
<CENTER><br><br><br>
<H3>Enter filename ...</H3>
<FORM action="test.php" method="POST">
<INPUT type="text" name="file" length="40">
<INPUT type="submit" name="do" value="Analyze now!">
</FORM>
</CENTER>
</BODY>
</HTML>
<?php
}
else
{
if(!is_file('./'.$file.'.php'))
{
die('file can not be open, sorry...');
}
else
{
$lines = file('./'.$file.'.php');
$buf = '';
foreach ($lines as $line_num => $line)
{
$buf .= trim($line);
}
//-------------------------------------------------
$params = array();$offset = 0;
$buf = explode('$',$buf);
$nr = 0;
for ( $i = 1; $i < count($buf); $i ++ )
{
$buf2 = $buf[$i];
$len = strlen($buf2);
$len2 = 0;
for ( $j = 0; $j < $len; $j ++ )
{
$buf3 = substr($buf2,$j,1);
if(!is_var_char($buf3))
{
$len2 = $j;
$j += $len;
}
}
if($len2 > 0)
{
$buf3 = substr($buf2,0,$len2);
$old = 0;
for($j=0;$j<count($params);$j++)
{
if($params[$j][0] == $buf3)
{
$params[$j][1] ++;
$old = 1;
$j += count($params);
}
}
if($old == 0)
{
$params[$nr][0] = $buf3;
$params[$nr][1] = 1;
$nr ++;
}
}
}
sort($params);
for($i=0;$i<count($params);$i++)
{
echo '<br> $'.$params[$i][0].' --> '.$params[$i][1];
}
}
}
//---------------------------------------------------------------------------------------
function is_var_char( $buf )
{
$nr = ord( $buf );
if( ($nr > 64 && $nr < 91 ) || ($nr > 96 && $nr < 123) || ($nr > 47 && $nr < 58) || ($nr == 95) )
{
return true;
}
return false;
}
?>

waraxe, thx for the script, primitive .. but what can i say , it COOL
thx one more time,
so you just found the variable with minimum used
eg:
$wew --> 12 times
$buf --> 39 times
$we --> 1 times
is it $we is $wew
so is it possible to do something nasty with that variable
once again, THX |
