cubrid_field_len — 获取指定字段的最大长度
resultresult 来自对 cubrid_execute() 的调用。
field_offset数字字段偏移量。 field_offset 从 0 开始。如果 field_offset 不存在，也会发出 E_WARNING 级别错误。
示例 #1 cubrid_field_len() 示例
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$result = cubrid_execute($conn, "SELECT * FROM game WHERE host_year=2004 AND nation_code='AUS' AND medal='G'");
$column_names = cubrid_column_names($result);
$column_types = cubrid_column_types($result);
printf("%-30s %-30s %-15s\n", "Column Names", "Column Types", "Column Maxlen");
for($i = 0, $size = count($column_names); $i < $size; $i++) {
$column_len = cubrid_field_len($result, $i);
printf("%-30s %-30s %-15s\n", $column_names[$i], $column_types[$i], $column_len);
}
cubrid_disconnect($conn);
?>以上示例将输出
Column Names Column Types Column Maxlen host_year integer 11 event_code integer 11 athlete_code integer 11 stadium_code integer 11 nation_code char 3 medal char 1 game_date date 10
