刚写的MySQL数据库结构文档生成器(V1.0)

phplover 2004-06-11 01:42:40

由于客户需要数据库结构文档，平时也没有写文档的习惯，所以写得比较很匆忙，如果大家发现bug，请即时回复或者给我短消息

为了方便，代码集中在一个文件中，可直接运行：
<?
ob_start();
error_reporting(0);
@set_time_limit(1000);

//---------------------------------参数配置-------------------------------------
$para_entry_key = "Author:Liu JH"; //加密解密key
$para_table_field = array( //名称，宽度(px)
'Field' => array('字段名称',120),
'Type' => array('类型',70),
'Scope' => array('范围',80),
'Default' => array('默认值',80),
'Peroperty' => array('属性',60),
'Memo' => array('字段说明',180),
);
$para_table_index = array(
'Type' => array('索引类型',60),
'KeyName' => array("名称",150),
'KeyField' => array("字段",250),
);
//表格样式定义
$para_table_style['innerHTML'] = "<TABLE border=1 cellspacing=0 cellpadding=0 borderColor=#000000 bordercolordark=#000000 style='border-collapse:collapse;font-size:12px'>";
