Use the string functions:http://www.php.net/manual/en/ref.strings.phpYou can use strlen to check the length of something, you can use trim to strip spaces at the beginning and ending of a string, replace characters, etc. To check a phone number, you might want to remove spaces, parenthese, dashes, periods, etc, then make sure the remaining string is a certain number of characters. You can use is_numeric to make sure they're all numbers. You can use filter_var to check the email address.http://www.php.net/manual/en/function.filter-var.php

(1)first you should check for the null values for each fieldget all the data into variables $var=$_POST['formelenetName']; you can use $_GET if method="get" in the form or $_REQUEST(this may work with both post and get) but i recommend you use form submision method as post.it is more secure. use $_POST if method="post"then check $var=""you may write a function for this or you may use big conditional check using if statement.if($var==""){print "enter a value";}check all the variable(2) validate password and confirmpassword$pass=$_POST['pass'];$cnfrpass=$_POST['cnfrpass'];if($pass==$cnfrpass){////}(3)use regular expressions to validate email,mobile number,phone numberwrite the regular expression as you write in javascript assign it to a variable $patternint ereg ( string $pattern , string $string )$string is may be email,mobile number or phone number you receive from the form submission.refer http://www.php.net/manual/en/function.ereg.php for further assistant with regular expression and ereg() function
