php 生成mysql数据字典代码
由于项目开发用了比较多的表 ，为了快速获取数据字典，通过php代码的方式来获取表结构和表注释。代码如下：
<?php /** * 生成mysql数据字典 */ header ( "Content-type: text/html; charset=utf-8" ); // 配置数据库 $dbserver = "localhost"; $dbusername = "数据库用户名"; $dbpassword = "数据库密码"; $database = "数据库名称"; // 其他配置 $title = '数据字典'; $mysql_conn = @mysql_connect ( "$dbserver", "$dbusername", "$dbpassword" ) or die ( "Mysql connect is error." ); mysql_select_db ( $database, $mysql_conn ); mysql_query ( 'SET NAMES utf8', $mysql_conn ); $table_result = mysql_query ( 'show tables', $mysql_conn ); // 取得所有的表名 while ( $row = mysql_fetch_array ( $table_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}'"; $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}'"; $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 foreach ( $tables as $k => $v ) { // $html .= '<p><h2>'. $v['TABLE_COMMENT'] . ' </h2>'; $html .= '<table border="1" cellspacing="0" cellpadding="0" align="center">'; $html .= '<caption>' . $v ['TABLE_NAME'] . ' ' . $v ['TABLE_COMMENT'] . '</caption>'; $html .= '<tbody><tr><th>字段名</th><th>数据类型</th><th>默认值</th> <th>允许非空</th> <th>自动递增</th><th>备注</th></tr>'; $html .= ''; foreach ( $v ['COLUMN'] as $f ) { $html .= '<tr><td class="c1">' . $f ['COLUMN_NAME'] . '</td>'; $html .= '<td class="c2">' . $f ['COLUMN_TYPE'] . '</td>'; $html .= '<td class="c3"> ' . $f ['COLUMN_DEFAULT'] . '</td>'; $html .= '<td class="c4"> ' . $f ['IS_NULLABLE'] . '</td>'; $html .= '<td class="c5">' . ($f ['EXTRA'] == 'auto_increment' ? '是' : ' ') . '</td>'; $html .= '<td class="c6"> ' . $f ['COLUMN_COMMENT'] . '</td>'; $html .= '</tr>'; } $html .= '</tbody></table></p>'; } // 输出 echo '<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>' . $title . '</title> <style> body,td,th {font-family:"宋体"; font-size:12px;} table{border-collapse:collapse;border:1px solid #CCC;background:#6089D4;} table caption{text-align:left; background-color:#fff; line-height:2em; font-size:14px; font-weight:bold; } table th{text-align:left; font-weight:bold;height:26px; line-height:25px; font-size:16px; border:3px solid #fff; color:#ffffff; padding:5px;} table td{height:25px; font-size:12px; border:3px solid #fff; background-color:#f0f0f0; padding:5px;} .c1{ width: 150px;} .c2{ width: 130px;} .c3{ width: 70px;} .c4{ width: 80px;} .c5{ width: 80px;} .c6{ width: 300px;} </style> </head> <body>'; echo '<h1 style="text-align:center;">' . $title . '</h1>'; echo $html; echo '</body></html>'; ?>
