Q:

Show all tables inside a MySQL database using PHP?

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>";
}

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

A:

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. Using information schema
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)

to OP
you have fetched just 1 row. fix like this:
while ( $tables = $result->fetch_array())
{
    echo $tmp[0]."<br>";
}

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>";
}

A:

Try this:
SHOW TABLES FROM nameOfDatabase;
