mysqli_stmt.bind_param
MYSQLI_STMT.BIND_PARAM(3) 1 MYSQLI_STMT.BIND_PARAM(3)mysqli_stmt::bind_param - Binds variables to a prepared statement as parameters
Object oriented style
SYNOPSIS
bool mysqli_stmt::bind_param (string $types, mixed &$var1, [mixed &$...])
DESCRIPTION
Procedural style
bool mysqli_stmt_bind_param (mysqli_stmt $stmt, string $types, mixed &$var1, [mixed &$...])
Bind variables for the parameter markers in the SQL statement that was passed to mysqli_prepare(3).
Note
If data size of a variable exceeds max. allowed packet size (max_allowed_packet), you have to specify b in $types and use
mysqli_stmt_send_long_data(3) to send the data in packets.
Note
Care must be taken when using mysqli_stmt_bind_param(3) in conjunction with call_user_func_array(3). Note that
mysqli_stmt_bind_param(3) requires parameters to be passed by reference, whereas call_user_func_array(3) can accept as a parameter a
list of variables that can represent references or values.
PARAMETERS
o $
stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).
o $types
- A string that contains one or more characters which specify the types for the corresponding bind variables:
Type specification chars
+----------+---------------------------------------------------+
|Character | |

| | Description |
| | |

| i | |
| | |
| | corresponding variable has type integer |
| | |
| d | |
| | |
| | corresponding variable has type double |
| | |
| s | |
| | |
| | corresponding variable has type string |
| | |
| b | |
| | |
| | corresponding variable is a blob and will be sent |
| | in packets |
| | |
+----------+---------------------------------------------------+
o $var1
- The number of variables and length of string $types must match the parameters in the statement.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Object oriented style
<?php
$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$stmt = $mysqli->prepare("INSERT INTO CountryLanguage VALUES (?, ?, ?, ?)");
$stmt->bind_param('sssd', $code, $language, $official, $percent);
$code = 'DEU';
$language = 'Bavarian';
$official = "F";
$percent = 11.2;
/* execute prepared statement */
$stmt->execute();
printf("%d Row inserted.
", $stmt->affected_rows);
/* close statement and connection */
$stmt->close();
/* Clean up table CountryLanguage */
$mysqli->query("DELETE FROM CountryLanguage WHERE Language='Bavarian'");
printf("%d Row deleted.
", $mysqli->affected_rows);
/* close connection */
$mysqli->close();
?>
Example #2
Procedural style
<?php
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (!$link) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$stmt = mysqli_prepare($link, "INSERT INTO CountryLanguage VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($stmt, 'sssd', $code, $language, $official, $percent);
$code = 'DEU';
$language = 'Bavarian';
$official = "F";
$percent = 11.2;
/* execute prepared statement */
mysqli_stmt_execute($stmt);
printf("%d Row inserted.
", mysqli_stmt_affected_rows($stmt));
/* close statement and connection */
mysqli_stmt_close($stmt);
/* Clean up table CountryLanguage */
mysqli_query($link, "DELETE FROM CountryLanguage WHERE Language='Bavarian'");
printf("%d Row deleted.
", mysqli_affected_rows($link));
/* close connection */
mysqli_close($link);
?>
The above examples will output:
1 Row inserted.
1 Row deleted.
