PHP生成数据字典

通过php代码生成MySQL数据字典，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   = "127.0.0.1";
$dbusername = "root";
$dbpassword = "root";
$database   = "demodb";

//其他配置
$mysql_conn = @mysql_connect($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);

$no_show_table = array();    //不需要显示的表
$no_show_field = array();   //不需要显示的字段

//取得所有的表名
while($row = mysql_fetch_array($table_result)){
	if(!in_array($row[0],$no_show_table)){
		$tables[]['TABLE_NAME'] = $row[0];
	}
}
//替换所以表的表前缀
if(!empty($_GET['prefix'])){ 
	$prefix = 'wxaj';
	foreach($tables as $key => $val){
		$tableName = $val['TABLE_NAME'];
		$string = explode('_',$tableName);
		if($string[0] != $prefix){  
			$string[0] = $prefix;  
			$newTableName = implode('_', $string);  
			mysql_query('rename table '.$tableName.' TO '.$newTableName);  
		}
	}
	echo "替换成功！";exit();
}

//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 column_name FROM ';
    $sql .= 'INFORMATION_SCHEMA.`KEY_COLUMN_USAGE` ';
    $sql .= 'WHERE ';
    $sql .= "table_name = '{$v['TABLE_NAME']}'  AND constraint_name = 'PRIMARY'";
    $pk_result = mysql_query($sql, $mysql_conn);
    $pks = [];
    while ($t = mysql_fetch_array($pk_result) ) {
        $pks[] = $t['column_name'];
    }
    $tables[$k]['PRIMARY_KEY'] = $pks;

    $sql  = 'SELECT * FROM ';
    $sql .= 'INFORMATION_SCHEMA.COLUMNS ';
    $sql .= 'WHERE ';
    $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database}'";

    $fields = [];
    $field_result = mysql_query($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) {
    $html .= '	<h3>' . ($k + 1) . '、' . $v['TABLE_COMMENT'] .'  （'. $v['TABLE_NAME']. '）</h3>'."\n";

    foreach ($v['COLUMN'] as $f) {

			$no_show_field[$v['TABLE_NAME']] = array();
