Converting one value in array to UPPER case

I am collecting data from the form. Before I put collected data That I got from $_POST[‘array’]) into a MySQL database I want to convert one of the values (let’s say value 1 in the array) in the array to upper case. How can it be done?

Below is the snippet of my code that I use to put data into a dtabase.

[code]

$result=exequery(“Select * from $tablename”, $tablename, $dbname);

$flds = mysql_num_fields($result);
$qry=” “;
$query = “Insert into $tablename Values( “;
for ($x =0; $x < $flds; $x++){

if(is_array($array[$x])){
$mval=””;
for($m=0; $m < count($array[$x]); $m++){
if($m+1 == count($array[$x])){
$mval.= AddSlashes($array[$x][$m]);

}else{
$mval.= AddSlashes($array[$x][$m]).”,”;
}
$fval = $mval;
}
}else{
$fval = AddSlashes($array[$x]);
}
$qry .= “‘$fval'”;
if ($x < $flds-1){
$qry.= “, “;
}
}
$query .= $qry.”)”;

$result=exequery($query, $tablename, $dbname);
if($result){
return $result;
}else{
return false;
}
