Before I slept last night this was the last thing I remember thinking about. I need to cast $fee to a double!! This works: if ( ereg ( "^(<\!TotalCharges>)([0-9]{1,4})(\.)([0-9]{1,})", $buffer, $regs)) { $fee .=$regs[2]; // Tens or hundreds column $fee .=$regs[3]; // decimal point $fee .=$regs[4]; // Cents echo "$fee"; // 3.17 } If I use $fee=$regs[0]; It doesn't. If $fee actually houses a string of "3.17" why wouldnt that convert when I add it to $sh ($sh += $fee;) ?? like: $sh += "3.17" The manual has an example: $foo = 1 + "10.5"; // $foo is double (11.5) What kinda of string conversion is happening to get a result of $sh = 0; ??? Is this because no conversion took place as per unix strtod? Thanks all for the help! -- Christopher C.M. Allen http://design.driver8.org/ Email: callen@driver8.org
