本文實(shí)例講述了PHP實(shí)現(xiàn)獲取并生成數(shù)據(jù)庫字典的方法。分享給大家供大家參考，具體如下：

/**

* 生成mysql數(shù)據(jù)字典

*/

header("Content-type:text/html;charset=utf-8");

// 配置數(shù)據(jù)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];

}

// 循環(huán)取得所有表的備注及表中列消息

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 = '';

// 循環(huán)所有表

//print_r($tables);

foreach($tables as $k => $v)

{

$html .= '

$html .= '
