显示使用PHP的MySQL数据库中的所有表? [英] Show all tables inside a MySQL database using PHP?

问题描述

我正在尝试显示数据库中的所有表.我已经尝试过了:

I'm trying to show all the tables in my database. I've tried this:

$sql = "SHOW TABLES";
$result = $conn->query($sql);
$tables = $result->fetch_assoc();
foreach($tables as $tmp)
{
    echo "$tmp <br>";
}

但是它只给我一个我知道有2个数据库的表名.我在做什么错了?

but it only gives me one table name in a database I know has 2. What am I doing wrong?

推荐答案

如何获取表格

1. SHOW TABLES

How to get tables

1. SHOW TABLES

mysql> USE test;
Database changed
mysql> SHOW TABLES;
+----------------+
| Tables_in_test |
+----------------+
| t1             |
| t2             |
| t3             |
+----------------+
3 rows in set (0.00 sec)

2. SHOW TABLES IN db_name

mysql> SHOW TABLES IN another_db;
+----------------------+
| Tables_in_another_db |
+----------------------+
| t3                   |
| t4                   |
| t5                   |
+----------------------+
3 rows in set (0.00 sec)

3.使用信息模式

mysql> SELECT TABLE_NAME
       FROM information_schema.TABLES
       WHERE TABLE_SCHEMA = 'another_db';
+------------+
| TABLE_NAME |
+------------+
| t3         |
| t4         |
| t5         |
+------------+
3 rows in set (0.02 sec)

到OP

您仅获取了1行.像这样修复:

to OP

you have fetched just 1 row. fix like this:

while ( $tables = $result->fetch_array())
{
    echo $tmp[0]."<br>";
}

我认为，information_schema会比SHOW TABLES

and I think, information_schema would be better than SHOW TABLES

SELECT TABLE_NAME
FROM information_schema.TABLES 
WHERE TABLE_SCHEMA = 'your database name'

while ( $tables = $result->fetch_assoc())
{
    echo $tables['TABLE_NAME']."<br>";
}
