mysqli_bind_param
(PHP 5 CVS only)
mysqli_bind_param -- Binds variables to a prepared statement as parameters
Description
bool
mysqli_bind_param ( object stmt, array types, mixed var1 [, mixed var2, ...])
mysql_bind_param() is used to bind variables for the parameter markers in the SQL statement that was passed to mysql_prepare(). The array types specifies the types for the diffrent bind variables. Valid array values are MYSQLI_BIND_INT, MYSQLI_BIND_DOUBLE, MYSQLI_BIND_STRING and MYSQLI_SEND_DATA.
Note: If data size of a variable exceeds max. allowed package size (max_allowed_package), you have to specify MYSQLI_SEND_DATA and use mysqli_send_long_data() to send the data in packages.
The number of variables and array values must match the number of parameters in the statement.
Example 1. Prepared statements Procedural style: <?php
/* connect to database */
$link = mysqli_connect("localhost", "mysql_user", "mysql_password", "mydb") or
die("Could not connect: " . mysqli_connect_error());
/* create mytable */
mysqli_query($link, "CREATE TABLE mytable (a int, b int, c varchar(30))");
/* prepare statement and bind variables for insert statements */
$stmt = mysqli_prepare($link, "INSERT INTO mytable VALUES (?, ?, ?)");
mysqli_bind_param($stmt, array(MYSQLI_BIND_INT, MYSQLI_BIND_INT,
MYSQLI_BIND_STRING), $a, $b, $c);
$a = 1;
$b = 2;
$c = "I prefer OpenSource software";
/* execute prepared statement */
mysqli_execute($stmt);
/* close statement and connection */
mysqli_close_stmt(stmt);
mysqli_close(link);
?> |
Object oriented style: <?php
/* connect to database */
$mysql = mysqli_connect("localhost", "mysql_user", "mysql_password", "mydb") or
die("Could not connect: " . mysqli_connect_error());
/* create mytable */
$mysql->query("CREATE TABLE mytable (a int, b int, c varchar(30))");
/* prepare statement and bind parameters */
$stmt = mysql->prepare("INSERT INTO mytable VALUES (?, ?, ?)");
$stmt->bind_param(array(MYSQLI_BIND_INT, MYSQLI_BIND_INT,
MYSQLI_BIND_STRING), $a, $b, $c);
$a = 1;
$b = 2;
$c = "I prefer opensource software";
/* execute prepared statement */
$stmt->execute();
/* close statement and connection */
$stmt->close();
$mysql->close();
