有時候沒有資料庫字典設計文件，根據現有的資料庫註釋進行生成一份
<?php header('content-type:text/html;charset=utf-8'); define('DB_HOST','192.168.11.7'); define('DB_USER','root'); define('DB_PASS','centos'); define('DB_NAME','new_admin'); define('DB_PORT',3306); define('DB_CHAR','utf8'); define('APPNAME','new_admin'); $dbh = new PDO("mysql:host=".DB_HOST.":".DB_PORT.";dbname=".DB_NAME,DB_USER,DB_PASS); $dbh->exec('set names ' . DB_CHAR); $sth = $dbh->prepare("SHOW TABLE STATUS FROM " . DB_NAME); $sth->execute(); $array = $sth->fetchAll(PDO::FETCH_ASSOC); $tab_count = count($array); echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="zh"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>'.APPNAME.'--資料字典</title> <style type="text/css"> table caption, table th, table td { padding:0.1em 0.5em 0.1em 0.5em; margin: 0.1em; vertical-align: top; } th { font-weight: bold; color: black; background: #D3DCE3; } table tr.odd th, .odd { background: #E5E5E5; } table tr.even th, .even { background: #f3f3f3; } .db_table{ border-top:1px solid #333; width: 100%; } .title{font-weight:bold;} </style> </head> <body> <div style="text-align:center;background:#D3DCE3;font-size:19px;"> <b>'.APPNAME.'--資料字典</b> </div> <div style="background:#f3f3f3;text-align:center;">（注：共'.$tab_count.'張表，按ctrl+F查詢關鍵字）</div>'."\n"; for($i=0;$i<$tab_count;$i++){ echo '<ul type="square">'."\n"; echo ' <li class="title">'; echo ($i+1).'、表名：[' . $array[$i]['Name'] .

效果是這樣的
