这篇文章主要介绍了PHP实现生成数据字典功能,涉及php针对mysql常见的连接、数据表查询、遍历、table表格构成等相关操作技巧,需要的朋友可以参考下
说了这么多废话了，终于开始写代码了：
<?php/*** 生成mysql数据字典*///配置数据库$dbserver = "127.0.0.1";$dbusername = "账号";$dbpassword = "密码";$database = "数据库";//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) { <div>……本2文来源gaodai.ma#com搞##代!^码@网3</div><code>搞代gaodaima码</code> $html .= '<tr><td class="c1">' . $f['COLUMN_NAME'] .
