ingres_fetch_array

(PHP 4 >= 4.0.2, PHP 5)

ingres_fetch_array -- Fetch a row of result into an array

Description

array ingres_fetch_array ( [int result_type [, resource link]] )

Avvertimento

Questa funzione è SPERIMENTALE. Ovvero, il comportamento di questa funzione, il nome di questa funzione, in definitiva tutto ciò che è documentato qui può cambiare nei futuri rilasci del PHP senza preavviso. Siete avvisati, l'uso di questa funzione è a vostro rischio.

ingres_fetch_array() Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

This function is an extended version of ingres_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.

If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you must use the numeric index of the column or make an alias for the column.

<?php

ingres_query("select t1.f1 as foo t2.f1 as bar from t1, t2");
$result = ingres_fetch_array();
$foo = $result["foo"];
$bar = $result["bar"];

?>

result_type can be INGRES_NUM for enumerated array, INGRES_ASSOC for associative array, or INGRES_BOTH (default).

Speed-wise, the function is identical to ingres_fetch_object(), and almost as quick as ingres_fetch_row() (the difference is insignificant).

Esempio 1. ingres_fetch_array() example

<?php
ingres_connect($database, $user, $password);

ingres_query("select * from table");
while ($row = ingres_fetch_array()) {
    echo $row["user_id"];  // using associative array
    echo $row["fullname"];
    echo $row[1];          // using enumerated array
    echo $row[2];
}
?>
