(posted this in the scripting forum as well, but figured it should go here) So, what's going on is this:
For our program, we had to create our own shell, and if the user pressed ctrl-c just at the cmdline, then this signal would be ignored, but if there is a foreground process running, let's... (0 Replies)

mysqli_use_result
MYSQLI_USE_RESULT(3) 1 MYSQLI_USE_RESULT(3)mysqli::use_result - Initiate a result set retrieval
Object oriented style
SYNOPSIS
mysqli_result mysqli::use_result (void )
DESCRIPTION
Procedural style
mysqli_result mysqli_use_result (mysqli $link)
Used to initiate the retrieval of a result set from the last query executed using the mysqli_real_query(3) function on the database con-
nection.
Either this or the mysqli_store_result(3) function must be called before the results of a query can be retrieved, and one or the other
must be called to prevent the next query on that database connection from failing.
Note
The mysqli_use_result(3) function does not transfer the entire result set from the database and hence cannot be used functions such
as mysqli_data_seek(3) to move to a particular row within the set. To use this functionality, the result set must be stored using
mysqli_store_result(3). One should not use mysqli_use_result(3) if a lot of processing on the client side is performed, since this
will tie up the server and prevent other threads from updating any tables from which the data is being fetched.
RETURN VALUES
Returns an unbuffered result object or FALSE if an error occurred.
EXAMPLES
Example #1
mysqli::use_result example
Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$query = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";
/* execute multi query */
if ($mysqli->multi_query($query)) {
do {
/* store first result set */
if ($result = $mysqli->use_result()) {
while ($row = $result->fetch_row()) {
printf("%s
", $row[0]);
}
$result->close();
}
/* print divider */
if ($mysqli->more_results()) {
printf("-----------------
");
}
} while ($mysqli->next_result());
}
/* 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
", mysqli_connect_error());
exit();
}
$query = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";
/* execute multi query */
if (mysqli_multi_query($link, $query)) {
do {
/* store first result set */
if ($result = mysqli_use_result($link)) {
while ($row = mysqli_fetch_row($result)) {
printf("%s
", $row[0]);
}
mysqli_free_result($result);
}
/* print divider */
if (mysqli_more_results($link)) {
printf("-----------------
");
}
} while (mysqli_next_result($link));
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
