警告

本扩展模块是实验性的。该模块的行为，包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

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).

例子 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]; } ?>
