Beispiele

Beispiel 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, SurfaceArea from Country ORDER BY Code LIMIT 5";

if (
$result = $mysqli->query($query)) {

  
/* Get field information for all columns */
  
while ($finfo = $result->fetch_field()) {

      
/* get fieldpointer offset */
      
$currentfield = $result->current_field;

      
printf("Column %d:\n", $currentfield);
      
printf("Name:    %s\n", $finfo->name);
      
printf("Table:    %s\n", $finfo->table);
      
printf("max. Len: %d\n", $finfo->max_length);
      
printf("Flags:    %d\n", $finfo->flags);
      
printf("Type:    %d\n\n", $finfo->type);
   }   
  
$result->close();
}

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

Beispiel 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, SurfaceArea from Country ORDER BY Code LIMIT 5";

if (
$result = mysqli_query($link, $query)) {

  
/* Get field information for all fields */
  
while ($finfo = mysqli_fetch_field($result)) {
 
      
/* get fieldpointer offset */
      
$currentfield = mysqli_field_tell($result);

      
printf("Column %d:\n", $currentfield);
      
printf("Name:    %s\n", $finfo->name);
      
printf("Table:    %s\n", $finfo->table);
      
printf("max. Len: %d\n", $finfo->max_length);
      
printf("Flags:    %d\n", $finfo->flags);
      
printf("Type:    %d\n\n", $finfo->type);
   }
  
mysqli_free_result($result);
}

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

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

Column 1:
Name:     Name
Table:    Country
max. Len: 11
Flags:    1
Type:     254

Column 2:
Name:     SurfaceArea
Table:    Country
max. Len: 10
Flags:    32769
Type:     4
