Using a variable in a PHP MySQL Query -

i user variable inside of php mysql query represent clause so:

$where= name=mark , address=4;  $query= "select * clients $where"; 

am doing correct? if not, correct so?

your php method correct, need single quotes around string in sql , need wrap string php variable quotes, variable should this:

$where = "name = 'mark' , address = 4"; $query = "select * clients {$where}";
