本文執行個體講述了PHP實現擷取並產生資料庫字典的方法。分享給大家供大家參考，具體如下：
<?php/** * 產生mysql資料字典 */header("Content-type:text/html;charset=utf-8");// 設定資料庫$database = array();$database['DB_HOST'] = 'localhost';$database['DB_NAME'] = 'test';$database['DB_USER'] = 'root';$database['DB_PWD'] = '';$mysql_conn = @mysql_connect("{$database['DB_HOST']}", "{$database['DB_USER']}", "{$database['DB_PWD']}") or die("Mysql connect is error.");mysql_select_db($database['DB_NAME'], $mysql_conn);$result = mysql_query('show tables', $mysql_conn);mysql_query("set names utf8");// 取得所有表名while ($row = mysql_fetch_array($result)){ $tables[]['TABLE_NAME'] = $row[0];}// 迴圈取得所有表的備忘及表中列訊息foreach($tables as $k => $v){ $sql = 'SELECT * FROM '; $sql .= 'information_schema.TABLES '; $sql .= 'WHERE '; $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database['DB_NAME']}'"; $table_result = mysql_query($sql, $mysql_conn); while ($t = mysql_fetch_array($table_result)) { $tables[$k]['TABLE_COMMENT'] = $t['TABLE_COMMENT']; } $sql = 'SELECT * FROM '; $sql .= 'information_schema.COLUMNS '; $sql .= 'WHERE '; $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database['DB_NAME']}'"; $fields = array(); $field_result = mysql_query($sql, $mysql_conn); while ($t = mysql_fetch_array($field_result)) { $fields[] = $t; } $tables[$k]['COLUMN'] = $fields;}mysql_close($mysql_conn);$html = '';// 迴圈所有表//print_r($tables);foreach($tables as $k => $v){ $html .= '<table border="1" cellspacing="0" cellpadding="0" align="center">'; $html .= '<caption>表名：' . $v['TABLE_NAME'] .
