Does PHP version 4.4.4 have try catch blocks? Or are they not untill PHP 5?

No. PHP5 >

Dang, any suggestions for this?

[code]
try {
    $db_percent = mysql_result($balancefeeresult,0,"percentcharge");
    $db_amount = mysql_result($balancefeeresult,0,"amount");
}catch (Exception $e) {
$exception = "true";
}
if($exception != "true"){
$db_percent = ($db_percent * .01);
$charge = ($db_percent * $db_amount);
}else{
$charge = NULL;
}[/code]

What i want to do, is if no amount comes out of db then set charge to null

[acp26b]

got it!
[code]
$balancefeenumber = mysql_numrows($balancefeeresult);
if(!$balancefeenumber){
$charge = 0;
}else{
$db_percent = mysql_result($balancefeeresult,0,"percentcharge");
$db_amount = mysql_result($balancefeeresult,0,"amount");
$db_percent = ($db_percent * .01);
$charge = ($db_percent * $db_amount);
}[/code]
