I'M TRYING TO CHANGE THE FOLLOWING JAVASCRIPT TO PHP, CAN SOMEONE PLEASE GIVE ME A RUN DOWN OF HOW TO GO ABOUT THIS??? THANKS IN ADVANCE
function calculate(num) {
var tax_on = 0;
var tax_to = 0;
num = num.replace(/[^0-9\.]/g,'');
if ( num <= 55000 ) {
tax_on = (num*0.005);
tax_to = (num*0.005);
}
if ( num > 55000 && num <= 250000 ) {
tax_on = (num*0.01)-275;
tax_to = (num*0.01)-275;
}
if ( num > 250000 && num <= 400000 ) {
tax_on = (num*0.015)-1525;
tax_to = (num*0.01)-275;
}
if ( num > 400000 ) {
tax_on = (num*0.02)-3525;
tax_to = (num*0.02)-4275;
}
var Sum = tax_on + tax_to;
document.forms.the_form.tax_on.value = format(tax_on,2);
document.forms.the_form.tax_to.value = format(tax_to,2);
document.forms.the_form.sum.value = format(Sum,2);
}
function calculate_com(num) {
var tax_on2 = 0;
var tax_to2 = 0;
num = num.replace(/[^0-9\.]/g,'');
if ( num <= 55000 ) {
tax_on2 = (num*0.005);
tax_to2 = (num*0.005);
}
else if ( num > 55000 && num <= 250000 ) {

}

document.forms.the_form2.tax_to2.value = format(tax_to2,2);
document.forms.the_form2.Sum2.value = format(Sum2,2);
}
function format(no, dp)
{
dp = Math.pow(10, dp);
var no = (Math.round(no * dp) / dp) + "";
var first = no.split(".");
var tmp = new Array;
var counter = 0;
var start = first[0].length % 3;

for (var i = start ; i < first[0].length ; i += 3)
tmp[counter++] = first[0].substr(i, 3);
first[0] = tmp.join(',');
return "$"+first.join('.');
