mysqli_stmt_fetch

(PHP 5, PHP 7)

mysqli_stmt::fetch -- mysqli_stmt_fetch — Fetch results from a prepared statement into the bound variables

Description

Object oriented style

public mysqli_stmt::fetch ( ) : bool

Procedural style

mysqli_stmt_fetch ( mysqli_stmt $stmt ) : bool

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().

Return Values

**Return Values**
Value	Description
`TRUE`	Success. Data has been fetched
`FALSE`	Error occurred
`NULL`	No more rows/data exists or data truncation occurred

Examples

Example #1 Object oriented style

<?php$mysqli = new mysqli("localhost", "my_user", "my_password", "world");/* check connection */if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}$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);?>
