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(); ?>
