mysqli_stmt_store_result

Transfers a result set from a prepared statement (PHP 5)
bool mysqli_stmt_store_result ( mysqli_stmt stmt )

Procedural style:

Object oriented style (method):

mysqli_stmt {
  bool store_result();
}

You must call mysqli_stmt_store_result() for every query that successfully produces a result set (SELECT, SHOW, DESCRIBE, EXPLAIN), and only if you want to buffer the complete result set by the client, so that the subsequent mysqli_stmt_fetch() call returns buffered data.

Note:

It is unnecessary to call mysqli_stmt_store_result() for other queries, but if you do, it will not harm or cause any notable performance in all cases. You can detect whether the query produced a result set by checking if mysqli_stmt_result_metadata() returns NULL.

Parameters

stmt

Procedural style only: A statement identifier returned by mysqli_stmt_init().

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example 1581. Object oriented style

<?php
/* Open a connection */
$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 Name LIMIT 20";
if (
$stmt = $mysqli->prepare($query)) {

   
/* execute query */
   
$stmt->execute();

   
/* store result */
   
$stmt->store_result();

   
printf("Number of rows: %d.\n", $stmt->num_rows);

   
/* free result */
   
$stmt->free_result();

   
/* close statement */
   
$stmt->close();
}

/* close connection */
$mysqli->close();
?>


Example 1582. Procedural style

<?php
/* Open a connection */
$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 Name LIMIT 20";
if (
$stmt = mysqli_prepare($link, $query)) {

   
/* execute query */
   
mysqli_stmt_execute($stmt);

   
/* store result */
   
mysqli_stmt_store_result($stmt);

   
printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt));

   
/* free result */
   
mysqli_stmt_free_result($stmt);

   
/* close statement */
   
mysqli_stmt_close($stmt);
}

/* close connection */
mysqli_close($link);
?>


The above example will output:

Number of rows: 20.
