(PHP 5, PHP 7)
Fetch results from a prepared statement into the bound variables
bool mysqli_stmt::fetch ( void )
Object oriented style
Procedural style
Fetch the result from a prepared statement into the variables bound by mysqli_stmt_bind_result().
Note:
Note that all columns must be bound by the application before calling mysqli_stmt_fetch().
Note:
Data are transferred unbuffered without calling mysqli_stmt_store_result() which can decrease performance (but reduces memory cost).
Parameters:
stmt
Procedural style only: A statement identifier returned by mysqli_stmt_init().
Returns:
Value | Description |
---|---|
TRUE | Success. Data has been fetched |
FALSE | Error occurred |
NULL | No more rows/data exists or data truncation occurred |
Examples:
Object oriented style
<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5"; if ($stmt = $mysqli->prepare($query)) { /* execute statement */ $stmt->execute(); /* bind result variables */ $stmt->bind_result($name, $code); /* fetch values */ while ($stmt->fetch()) { printf ("%s (%s)\n", $name, $code); } /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>
Procedural style
<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5"; if ($stmt = mysqli_prepare($link, $query)) { /* execute statement */ mysqli_stmt_execute($stmt); /* bind result variables */ mysqli_stmt_bind_result($stmt, $name, $code); /* fetch values */ while (mysqli_stmt_fetch($stmt)) { printf ("%s (%s)\n", $name, $code); } /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>
The above examples will output:
Rockford (USA) Tallahassee (USA) Salinas (USA) Santa Clarita (USA) Springfield (USA)
