Examples

Example 1509. 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();
?>


Example 1510. 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);
?>


The above example will output:

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
