Detailed explanation of the steps to generate data dictionary in PHP

This time I will bring you a detailed explanation of the steps to generate a data dictionary in PHP. What are the precautions for generating a data dictionary in PHP? Here is a practical case, let's take a look.

I’m pressed for time recently, and I don’t have time to post a blog. I’d like to take advantage of the time now to share a knowledge point with you. When we are doing development, we may often encounter the problem of analyzing the database and making a data dictionary. Now the benefit is here. You only need to follow the link I sent to easily help you design the data dictionary. You don’t need to download the data dictionary tool. As a developer, you should be able to get this knowledge with just a few lines of code. So I won’t go into nonsense now. Look at the code below. You only need to change your database account and Just enter the password and run it.

After talking so much nonsense, I finally started writing code:

<?php /**
* 生成mysql数据字典
*/
//配置数据库
$dbserver  = "127.0.0.1";
$dbusername = "账号";
$dbpassword = "密码";
$database   = "数据库";
//其他配置
$title = &#39;数据字典&#39;;
$mysql_conn = @mysql_connect("$dbserver", "$dbusername", "$dbpassword") or die("Mysql connect is error.");
mysql_select_db($database, $mysql_conn);
mysql_query(&#39;SET NAMES utf8&#39;, $mysql_conn);
$table_result = mysql_query(&#39;show tables&#39;, $mysql_conn);
//取得所有的表名
while ($row = mysql_fetch_array($table_result)) {
   $tables[][&#39;TABLE_NAME&#39;] = $row[0];
}
//循环取得所有表的备注及表中列消息
foreach ($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></p><h2 id="v-TABLE-COMMENT">'. $v['TABLE_COMMENT'] . ' </h2>';
   $html .= '

';    $html .= '';    $html .= '        ';    $html .= '';    foreach ($v['COLUMN'] AS $f) {      $html .= '';      $html .= '';      $html .= '';      $html .= '';      $html .= '';      $html .= '';      $html .= '';    }    $html .= '

' . $v['TABLE_NAME'] .' '. $v['TABLE_COMMENT']. '

字段名	数据类型	默认值	允许非空	自动递增	备注
' . $f['COLUMN_NAME'] . '	' . $f['COLUMN_TYPE'] . '	' . $f['COLUMN_DEFAULT'] . '	' . $f['IS_NULLABLE'] . '	' . ($f['EXTRA']=='auto_increment'?'是':' ') . '	' . $f['COLUMN_COMMENT'] . '

'; } //输出 echo ' '; echo '

'.$title.'

'; echo $html; echo ''; ?>
