Description

Procedural style:

int maxdb_stmt_param_count ( resource stmt )

Object oriented style (property):

class stmt {

int param_count

}

maxdb_stmt_param_count() returns the number of parameter markers present in the prepared statement.

Example

Esempio 1. Object oriented style


<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

if ($stmt = $maxdb->prepare("SELECT name FROM hotel.city WHERE name=? OR state=?")) {

   $marker = $stmt->param_count;
   printf("Statement has %d markers.\n", $marker);

   /* close statement */
   $stmt->close();
}

/* close connection */
$maxdb->close();
?>

Esempio 2. Procedural style


<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

if ($stmt = maxdb_prepare($link, "SELECT name FROM hotel.city WHERE name=? OR state=?")) {

   $marker = maxdb_stmt_param_count($stmt);
   printf("Statement has %d markers.\n", $marker);

   /* close statement */
   maxdb_stmt_close($stmt);
}

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

Statement has 2 markers.
