mysqli_field_count

(no version information, might be only in CVS)

mysqli->field_count -- Returns the number of columns for the most recent query

Syntax

Procedural style:

int mysqli_field_count ( mysqli link )

Object oriented style (method):

class mysqli {

int field_count ( void )

}

Returns the number of columns for the most recent query on the connection represented by the link parameter. This function can be useful when using the mysqli_store_result() function to determine if the query should have produced a non-empty result set or not without knowing the nature of the query.

Return Values

An integer representing the number of fields in a result set

Examples

Example 1. Object oriented style

<?php
$mysqli
= new mysqli("localhost", "my_user", "my_password", "test");

$mysqli->query( "DROP TABLE IF EXISTS friends");
$mysqli->query( "CREATE TABLE friends (id int, name varchar(20))");

$mysqli->query( "INSERT INTO friends VALUES (1,'Hartmut'), (2, 'Ulf')");


$mysqli->real_query($HTTP_POST_VARS['query']);

if (
mysqli_field_count($link)) {
    
/* this was a select/show or describe query */
    
$result = $mysqli->store_result();
    
    
/* process resultset */
    
$row = $result->fetch_row();

    
/* free resultset */
    
$result->close();
}

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

Example 2. Procedural style

<?php
$link
= mysqli_connect("localhost", "my_user", "my_password", "test");

mysqli_query($link, "DROP TABLE IF EXISTS friends");
mysqli_query($link, "CREATE TABLE friends (id int, name varchar(20))");

mysqli_query($link, "INSERT INTO friends VALUES (1,'Hartmut'), (2, 'Ulf')");

mysqli_real_query($link, $HTTP_POST_VARS['query']);

if (
mysqli_field_count($link)) {
    
/* this was a select/show or describe query */
    
$result = mysqli_store_result($link);
    
    
/* process resultset */
    
$row = mysqli_fetch_row($result);

    
/* free resultset */
    
mysqli_free_result($result);
}

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