$gen=$_POST['gen'];
 
 
$result = mysqli_query($link, "SELECT count(*) FROM $gen");
$row = mysqli_fetch_array($result, MYSQLI_NUM);
$row[0]++;
$pollname="poll".$gen.$row[0];
echo $pollname; 
 
 
 
echo "subject - ".$subject."<br />op1 - ".$op1."<br />op2 - ".$op2."<br />op3 - ".$op3."<br />op4 - ".$op4."<br />op5 - ".$op5."<br />gen - ".$gen;
 
$sql = "CREATE TABLE $pollname (

Try this, if that doesnt work, tell me what error you are getting.

Vibrazy
$f = "INSERT INTO $pollname (op1,op2,op3,op4,op5,subject,gen) VALUES ('".$op1."','".$op2."','".$op3."','".$op4."','".$op5."','".$subject."','".$gen."')"; 
mysqli_query($link,$f);

Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Day','Valentine's Day','Favorite holiday?','other')' at line 1

$subject = $_POST['subject'];
$op1 = mysql_real_escape_string ($_POST['op1']);
$op2 = mysql_real_escape_string ($_POST['op2']);
$op3 = mysql_real_escape_string ($_POST['op3']);
$op4 = mysql_real_escape_string ($_POST['op4']);
$op5 = mysql_real_escape_string ($_POST['op5']);
$op6 = mysql_real_escape_string ($_POST['op6']);
$op7 = mysql_real_escape_string ($_POST['op7']);
$op8 = mysql_real_escape_string ($_POST['op8']);
$op9 = mysql_real_escape_string ($_POST['op9']);
$op10 = mysql_real_escape_string ($_POST['op10']);
$op11 = mysql_real_escape_string ($_POST['op11']);
$op12 = mysql_real_escape_string ($_POST['op12']);
$gen = mysql_real_escape_string ($_POST['gen']);


Now you can use it in a query

You can also do the following instead of individually changing the values
foreach($_POST as $key => $val){
${$key} = mysql_real_escape_string($val);
}
