用過dedecms系統(tǒng)的朋友都會(huì)看到在后臺(tái)的數(shù)據(jù)表管理中我們可以在后臺(tái)看到表的數(shù)據(jù)表結(jié)構(gòu)及字符長(zhǎng)度了,下面我也整理了一個(gè)PHP生成MySQL數(shù)據(jù)字典數(shù)據(jù)表結(jié)構(gòu)例子,大家一起來(lái)看看.

程序代碼如下:

<?php

/**

* 生成mysql數(shù)據(jù)字典

*/

// 配置數(shù)據(jù)庫(kù)

$database = array();

$database['DB_HOST'] = '127.0.0.1';

$database['DB_NAME'] = 'test';

$database['DB_USER'] = 'testuser';

$database['DB_PWD'] = '123456';

$mysql_conn = @mysql_connect("{$database['DB_HOST']}", "{$database['DB_USER']}", "{$database['DB_PWD']}") or die("Mysql connect is error.");

mysql_select_db($database['DB_NAME'], $mysql_conn);

$result = mysql_query('show tables', $mysql_conn);

mysql_query('SET NAME GBK', $mysql_conn);

// 取得所有表名

while ($row = mysql_fetch_array($result))

{

$tables[]['TABLE_NAME'] = $row[0];

}

// 循環(huán)取得所有表的備注及表中列消息

foreach($tables as $k => $v)

{

$sql = 'SELECT * FROM ';

$sql .= 'INFORMATION_SCHEMA.TABLES ';

$sql .= 'WHERE ';

$sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database['DB_NAME']}'";

$table_result = mysql_query($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['DB_NAME']}'";

$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 = '';

// 循環(huán)所有表

foreach($tables as $k => $v)

{

$html .= '<table border="1" cellspacing="0" cellpadding="0" align="center">';

$html .= '<caption>表名：' . $v['TABLE_NAME'] . ' ' . $v['TABLE_COMMENT'] . '</caption>';

$html .= '<tbody><tr><th>字段名</th><th>數(shù)據(jù)類型</th><th>默認(rèn)值</th><th>允許非空</th><th>自動(dòng)遞增</th><th>備注</th></tr>';

$html .= '';

foreach($v['COLUMN'] AS $f)

{

  $html .= '<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>';  //開源軟件:Vevb.com

  $html .= '<td class="c6">' . $f['COLUMN_COMMENT'] . '</td>';

  $html .= '</tr>';

}

$html .= '</tbody></table></p>';

}

// 輸出

echo '<html>

    <meta charset="utf-8">
