有时候我们拿到别人的数据库，却没有数据字典，这个php小程序帮你轻松解决。

代码是网上找到的，当然，这段代码也仅仅是生成了数据字典，视图，存储过程等等是木有的哦。

<?php
/**
 * 生成mysql数据字典
 */

//配置数据库
$dbserver   = "127.0.0.1";
$dbusername = "root";
$dbpassword = "";
$database      = "";
//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 id="v-TABLE-COMMENT">". $v["TABLE_COMMENT"] . " </h2>";
    $html .= "<table  border="1" cellspacing="0" cellpadding="0" align="center">";
    $html .= "<caption>" . $v["TABLE_NAME"] ."  ". $v["TABLE_COMMENT"]. "</caption>";
    $html .= "<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 .= "</table></p>";
}

//输出
echo "<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>".$title."</title>
<style>
body,td,th {font-family:"宋体"; font-size:12px;}
table{border-collapse:collapse;border:1px solid #CCC;background:#efefef;}
table caption{text-align:left; background-color:#fff; line-height:2em; font-size:14px; font-weight:bold; }
table th{text-align:left; font-weight:bold;height:26px; line-height:26px; font-size:12px; border:1px solid #CCC;}
table td{height:20px; font-size:12px; border:1px solid #CCC;background-color:#fff;}
.c1{ width: 120px;}
.c2{ width: 120px;}
.c3{ width: 70px;}
.c4{ width: 80px;}
.c5{ width: 80px;}
.c6{ width: 270px;}
</style>
</head>
<body>";
echo "<h1 id="title">".$title."</h1>";
echo $html;
echo "</body></html>";

?>
