Thanx for everyone. Now I'm little bit ok with ajax. These are my php form and ajax file. I want to check array values in php file using ajax function. I tried just one variable and it didn't work. Could you please tell me when I went wrong?

        }
    } 
	return request;

function add(Name,Gender,PhnNo,Email,Address){
//alert ('test')
if (PhnNo){
	PhnNo= document.getElementById(PhnNo).value
	var regex = /^\d{11}$/;
	if( !PhnNo.match(regex) ) 
 		return "Number is incorrect!!";
	}

Your call to the add() function doesn't have any parameters, so the function won't do anything. There's no reference to the Ajax function. If you want to use PHP code to validate, then there's no point in using JavaScript validation as well. Make an Ajax request to your PHP validation script instead.
