mysqli_stmt::bind_result -- mysqli_stmt_bind_result — Binds variables to a prepared statement for result storage
Object oriented style
public mysqli_stmt::bind_result ( mixed &$var , mixed &...$vars ) : bool
Procedural style
mysqli_stmt_bind_result ( mysqli_stmt $stmt , mixed &$var , mixed &...$vars ) : bool
Binds columns in the result set to variables.
When mysqli_stmt_fetch() is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the specified variables var
/vars
.
Note:
Note that all columns must be bound after mysqli_stmt_execute() and prior to calling mysqli_stmt_fetch(). Depending on column types bound variables can silently change to the corresponding PHP type.
A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time mysqli_stmt_fetch() is called.
stmt
Procedural style only: A statement identifier returned by mysqli_stmt_init().
var
The first variable to be bound.
vars
Further variables to be bound.
Returns true
on success or false
on failure.
Example #1 Object oriented style
<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* prepare statement */ if ($stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) { $stmt->execute(); /* bind variables to prepared statement */ $stmt->bind_result($col1, $col2); /* fetch values */ while ($stmt->fetch()) { printf("%s %s\n", $col1, $col2); } /* close statement */ $stmt->close(); } /* 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\n", mysqli_connect_error()); exit(); } /* prepare statement */ if ($stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) { mysqli_stmt_execute($stmt); /* bind variables to prepared statement */ mysqli_stmt_bind_result($stmt, $col1, $col2); /* fetch values */ while (mysqli_stmt_fetch($stmt)) { printf("%s %s\n", $col1, $col2); } /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>
