php - Call to undefined method mysqli_stmt::fetchColumn() -

-

I'm trying to get the number of rows returning from a SQL query 

  Need_once ("inc / db_const.php"); $ Date = $ _ receive ['date_rdv']; $ Mysqli = new mysqli (DB_HOST, DB_USER, DB_PASS, DB_NAME); If ($ mysqli-> connect_errno) {echo " mysql error does not {$ mysqli-> connect_errno}: {$ mysqli-> connect_error}  "; Go out(); } $ Query_check = "Select number (*) from plan_cl where date_plannig =?"; $ Statement_check = $ mysqli-> Ready ($ query_check); $ Statement_check-> Bind_param ('s', $ date); $ Statement_check-> Executed (); $ Rdv_verif = $ statement_check-> FetchColumn (); Echo $ rdv_verif;

But this gives me this error 

  r: call the undefined method mysqli_stmt :: fetchColumn ()

Anyone can give me some solution to solve this problem

any Mysqli_stmt :: fetchColumn is not () View in MySQLi This is a PDO method.

To use MySQLi 

  $ rdv_verif = $ statement_check-> Mysqli_stmt_num_rows (); Echo $ rdv_verif;

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
