msql_fetch_array — Fetch row as array
$result
[, int $result_type
] )msql_fetch_array() is an extended version of msql_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.
An important thing to note is that using msql_fetch_array() is NOT significantly slower than using msql_fetch_row(), while it provides a significant added value.
resultresource 型的结果集。此结果集来自对 msql_query() 的调用。
result_type
A constant that can take the following values:
MSQL_ASSOC, MSQL_NUM, and
MSQL_BOTH with MSQL_BOTH being
the default.
Returns an array that corresponds to the fetched row, or FALSE if
there are no more rows.
Example #1 msql_fetch_array() example
<?php
$con = msql_connect();
if (!$con) {
die('Server connection problem: ' . msql_error());
}
if (!msql_select_db('test', $con)) {
die('Database connection problem: ' . msql_error());
}
$result = msql_query('SELECT id, name FROM people', $con);
if (!$result) {
die('Query execution problem: ' . msql_error());
}
while ($row = msql_fetch_array($result, MSQL_ASSOC)) {
echo $row['id'] . ': ' . $row['name'] . "\n";
}
msql_free_result($result);
?>
