mysqli_stmt::get_result
mysqli_stmt_get_result
Gets a result set from a prepared statement as a mysqli_result object
Description
Object-oriented style
public mysqli_resultfalse mysqli_stmt::get_result()
mysqli_resultfalse mysqli_stmt_get_result(mysqli_stmt $statement
)
Note:
Available only with mysqlnd.
Note:
This function cannot be used together
with mysqli_stmt_store_result. Both of these functions
retrieve the full result set from the MySQL server.
Parameters
-
statement
-
Procedural style only: A mysqli_stmt object
returned by mysqli_stmt_init.
Return Values
Returns false
on failure. For successful queries which produce a result set, such as SELECT, SHOW, DESCRIBE
or
EXPLAIN
, mysqli_stmt_get_result will return
a mysqli_result object. For other successful queries, mysqli_stmt_get_result will
return false
. The mysqli_stmt_errno function can be
used to distinguish between the two reasons for false
; due to a bug, prior to PHP 7.4.13,
mysqli_errno had to be used for this purpose.
Errors/Exceptions
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.
Examples
Example #1 Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = $mysqli->prepare($query);
$stmt->bind_param("s", $continent);
$continentList = array('Europe', 'Africa', 'Asia', 'North America');
foreach ($continentList as $continent) {
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_array(MYSQLI_NUM)) {
foreach ($row as $r) {
print "$r ";
}
print "\n";
}
}
Example #2 Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, Population, Continent FROM Country WHERE Continent=? ORDER BY Name LIMIT 1";
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_bind_param($stmt, "s", $continent);
$continentList= array('Europe', 'Africa', 'Asia', 'North America');
foreach ($continentList as $continent) {
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
while ($row = mysqli_fetch_array($result, MYSQLI_NUM)) {
foreach ($row as $r) {
print "$r ";
}
print "\n";
}
}
The above examples will output
something similar to:
Albania 3401200 Europe
Algeria 31471000 Africa
Afghanistan 22720000 Asia
Anguilla 8000 North America
