mysqli_fetch_object

Fetches one row of data from the result set and returns it as an object, where each property represents the name of the result set’s column. Each subsequent call to this function will return the next row within the result set, or null if there are no more rows.

If two or more columns of the result have the same name, the last column will take precedence and overwrite any previous data. To access multiple columns with the same name, mysqli_fetch_row() may be used to fetch the numerically indexed array, or aliases may be used in the SQL query select list to give columns different names.

Note: This function sets the properties of the object before calling the object constructor.

Note: Field names returned by this function are case-sensitive.

Note: This function sets NULL fields to the PHP null value.

Parameters

The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.

An optional array of parameters to pass to the constructor for class objects.

Return Values

Returns an object representing the fetched row, where each property represents the name of the result set’s column, null if there are no more rows in the result set, or false on failure.

Changelog

Version Description
8.0.0 constructor_args now accepts [] for constructors with 0 parameters; previously an exception was thrown.

Examples

Example #1 mysqli_result::fetch_object() example

mysqli_report ( MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT );
$mysqli = new mysqli ( «localhost» , «my_user» , «my_password» , «world» );

$query = «SELECT Name, CountryCode FROM City ORDER BY ID DESC» ;

$result = $mysqli -> query ( $query );

/* fetch object array */
while ( $obj = $result -> fetch_object ()) printf ( «%s (%s)\n» , $obj -> Name , $obj -> CountryCode );
>

mysqli_report ( MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT );
$link = mysqli_connect ( «localhost» , «my_user» , «my_password» , «world» );

$query = «SELECT Name, CountryCode FROM City ORDER BY ID DESC» ;

$result = mysqli_query ( $link , $query );

/* fetch associative array */
while ( $obj = mysqli_fetch_object ( $result )) printf ( «%s (%s)\n» , $obj -> Name , $obj -> CountryCode );
>

The above examples will output something similar to:

Pueblo (USA) Arvada (USA) Cape Coral (USA) Green Bay (USA) Santa Clara (USA)

mysql_fetch_row

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

Description

Returns a numerical array that corresponds to the fetched row and moves the internal data pointer ahead.

Parameters

The result resource that is being evaluated. This result comes from a call to mysql_query() .

Return Values

Returns an numerical array of strings that corresponds to the fetched row, or false if there are no more rows.

mysql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.

Examples

Example #1 Fetching one row with mysql_fetch_row()

$result = mysql_query ( «SELECT id,email FROM people WHERE » );
if (! $result ) echo ‘Could not run query: ‘ . mysql_error ();
exit;
>
$row = mysql_fetch_row ( $result );

echo $row [ 0 ]; // 42
echo $row [ 1 ]; // the email value
?>

Notes

Note: This function sets NULL fields to the PHP null value.

  • mysql_fetch_assoc() — Fetch a result row as an associative array
  • mysql_fetch_object() — Fetch a result row as an object
  • mysql_data_seek() — Move internal result pointer
  • mysql_fetch_lengths() — Get the length of each output in a result
  • mysql_result() — Get result data

User Contributed Notes 4 notes

Maybe worth pointing out that all the fields returned by this (and other?) calls are returned with type string. This had me puzzled for quite some time.

require ‘prhlavicka.php’ ;
pis_hlavicku ( ‘Vypis článků’ );

require_once ‘db.php’ ;
$kom = new server ();
$sql = $kom -> query ( «SELECT autor,nazev,obsah FROM `Clanky_Sadek`» );
while ( $data = mysql_fetch_row ( $sql )) ECHO ‘
—AUTOR—
‘ . $data [ 0 ]. ‘
__NÁZEV ČLÁNKU__
‘ . $data [ 1 ]. ‘
..OBSAH ČLÁNKU..
‘ . $data [ 2 ]; >

to print an array, simply use print_r(array name)

like this:
$myrow = mysql_fetch_row($result);
echo «

";
print_r($myrow);
echo "

«;

this will output the array in a readable form, with the index, too. Don’t forget the ‘pre’ tags or the output will be on a single line.

$esi = mysql_list_tables ( $db ); $ris = mysql_fetch_row ( $esi );
//example: $db has >= 1 tabs
echo var_dump ( $ris );
//echoes only array(1). solution:
while( $ris = mysql_fetch_row ( $esi )) echo $ris [ 0 ];
/*debug:
$ris=array(«1st_tab»); . $ris=array(«n_tab»);$ris=false;*/
while ( $ris []= mysql_fetch_row ( $esi ));
//debug:$ris=array(array(«1st_tab»), . array(«n_tab»));
echo $ris [ n ][ 0 ]; //echo:»n_tab»
echo $ris [ 0 ][ n ]; //echo:array | null
?>
