php生成mysql数据库数据字典的程序代码,比较实用,具体代码如下:
<?php header('Content-type:text/html;charset=utf-8'); /** * 生成mysql数据字典 * * @author www.phpernote.com<403656085@qq.com> */ //配置数据库 $dbserver="localhost"; $dbusername="root"; $dbpassword="root"; $database='test'; //其他配置 $title=$database.' 数据库数据字典'; $mysql_conn=@mysql_connect("$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 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.='<table border="1" cellspacing="0" cellpadding="0" align="center">'; $html.='<caption>'.$v['TABLE_COMMENT'].'(<span class="cr">'. $v['TABLE_NAME'].'</span>)</caption>'; $html.='<tbody><tr><th width="120">字段名</th><th width="120">数据类型</th><th width="120">默认值</th> <th width="65">允许非空</th> <th width="360">备注</th></tr>'; $html.=''; foreach($v['COLUMN'] AS $f){ $html.='<tr><td>'.$f['COLUMN_NAME'].'</td>'; $html.='<td>'.$f['COLUMN_TYPE'].'</td>'; $html.='<td>'.$f['COLUMN_DEFAULT'].'</td>'; $html.='<td>'.$f['IS_NULLABLE'].'</td>'; $html.='<td>'.$f['COLUMN_COMMENT'].($f['EXTRA']=='auto_increment'?',自动递增':'').'</td>'; $html.='</tr>'; } $html.='</tbody></table></p>'; } //输出 echo '<html> <head> <title>'.$title.'</title> <style> body,td,th{font-family:"宋体"; font-size:12px;} table{border-collapse:collapse;border:1px solid #CCC;background:#efefef;} 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:26px; font-size:12px; border:1px solid #CCC;} table td{height:20px; font-size:12px; border:1px solid #CCC;background-color:#fff;} table caption,table td,table th{padding:0px 3px;} #version{text-align:center;margin:0 auto;} .cr{color:#ff0033;} </style> </head> <body>'; echo '<h1>'.$title.'</h1>'; echo $html; $version='<p id="version">made by <a href="http://www.phpernote.com" target="_blank">www.phpernote.com</a></p>'; echo '<p> </p>'.$version.'<p> </p></body></html>';
