PHP实现获取并生成数据库字典的方法

本文实例讲述了PHP实现获取并生成数据库字典的方法。分享给大家供大家参考，具体如下：

<?php/** * 生成mysql数据字典 */header（"Content-type:text/html;charset=utf-8"）;// 配置数据库$database = array（）;$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"] = $row[0];}// 循环取得所有表的备注及表中列消息foreach（$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）;$html = "";// 循环所有表//print_r（$tables）;foreach（$tables as $k => $v）{$html .= "<table border="1" cellspacing="0" cellpadding="0" align="center">";$html .= "<caption>表名：" . $v["TABLE_NAME"] .
