• 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'] . '&nbsp;</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">&nbsp;' . $f ['COLUMN_DEFAULT'] . '</td>';
            $html .= '<td class="c4">&nbsp;' . $f ['IS_NULLABLE'] . '</td>';
            $html .= '<td class="c5">' . ($f ['EXTRA'] == 'auto_increment' ? '是' : '&nbsp;') . '</td>';
            $html .= '<td class="c6">&nbsp;' . $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{  150px;}
    .c2{  130px;}
    .c3{  70px;}
    .c4{  80px;}
    .c5{  80px;}
    .c6{  300px;}
    </style>
    </head>
    <body>';
    echo '<h1 style="text-align:center;">' . $title . '</h1>';
    echo $html;
    echo '</body></html>';
    
    ?>
