mysqli_stmt::fetch -- mysqli_stmt_fetch — Fetch results from a prepared statement into the bound variables
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).
Value | Description |
---|---|
true |
Success. Data has been fetched |
false |
Error occurred |
null |
No more rows/data exists or data truncation occurred |
If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR
) and the requested operation fails,
a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT
,
a mysqli_sql_exception is thrown instead.
Example #1 Object-oriented style
<?php$mysqli = new mysqli("localhost", "my_user", "my_password", "world");/* check connection */if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}$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();?>
Example #2 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);?>
