Just thought I'd share these helper functions that I use to simplify processing of query
results a bit:
<?php
// For a simple query that should return a single value, this returns just that value (or FALSE) so
you can process it immediately
function db_result_single($result) {
return ($row = mysql_fetch_row($result)) && isset($row[0]) ? $row[0] : false;
}
// Returns the rows as an array of rows
// Providing a key_column gives you access to specific rows (e.g. if
(isset($result_array[$user_id])) ...)
function db_result_array($result, $key_column = null) {
for ($array = array(); $row = mysql_fetch_assoc($result); isset($row[$key_column]) ?
$array[$row[$key_column]] = $row : $array[] = $row);
return $array;
}
// Returns an array of a single column of data that can optionally be keyed from second column (e.g.
an array of user names keyed by user id)
function db_result_array_values($result) {
for ($array = array(); $row = mysql_fetch_row($result); isset($row[1]) ? $array[$row[1]] = $row[0]
: $array[] = $row[0]);
return $array;
}
?>
Naturally, comments are welcome.
