本文实例讲述了PHP实现获取并生成数据库字典的方法。分享给大家供大家参考，具体如下：
$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);$html = '';// 循环所有表//print_r($tables);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>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 .= '<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>'; } $html .= '</tbody></table></p>';}/* 生成word *///header ( "Content-type:application/vnd.ms-word" );//header ( "Content-Disposition:attachment;filename={$database['DB_NAME']}数据字典.doc" );/* 生成excel*///header ( "Content-type:application/vnd.ms-excel" );//header ( "Content-Disposition:attachment;filename={$database['DB_NAME']}数据字典.xls" );// 输出echo ' <meta charset="utf-8"> <title>自动生成数据字典</title> <style> body,td,th {font-family:"宋体"; font-size:12px;} table,h1,p{width:960px;margin:0px auto;} table{border-collapse:collapse;border:1px solid #CCC;background:#efefef;} table caption<span style="color:transparent">~来1源gaodai#ma#com搞*代#码1网</span><abbr>搞代gaodaima码</abbr>{text-align:left; background-color:#fff; line-height:2em; font-size:14px; font-weight:bold; } table th{text-align:left; font-weight:bold;height:26px; line-height:26px; font-size:12px; border:1px solid #CCC;padding-left:5px;} table td{height:20px; font-size:12px; border:1px solid #CCC;background-color:#fff;padding-left:5px;} .c1{ width: 150px;} .c2{ width: 150px;} .c3{ width: 80px;} .c4{ width: 100px;} .c5{ width: 100px;} .c6{ width: 300px;} </style> <body>';echo '<h1 style="text-align:center">'.$database['DB_NAME'].'数据字典</h1>';echo '<p style="text-align:center;margin:20px auto">生成时间：' . date('Y-m-d H:i:s') .

希望本文所述对大家PHP程序设计有所帮助。
