Bagaimana saya bisa mendapatkan tabel dari database di php?

Sejauh ini Anda telah mempelajari cara membuat database dan tabel serta memasukkan data. Sekarang saatnya mengambil data yang telah disisipkan pada tutorial sebelumnya. Pernyataan SQL SELECT_ digunakan untuk memilih record dari tabel database. Sintaks dasarnya adalah sebagai berikut

PILIH nama_kolom1, nama_kolom2, nama_kolom DARI nama_tabel;

Mari kita membuat kueri SQL menggunakan pernyataan SELECT, setelah itu kita akan mengeksekusi kueri SQL ini dengan meneruskannya ke fungsi PHP mysqli_query() untuk mengambil data tabel

Pertimbangkan tabel database orang kami memiliki catatan berikut

+----+------------+-----------+----------------------+
| id | first_name | last_name | email                |
+----+------------+-----------+----------------------+
|  1 | Peter      | Parker    | [email protected] |
|  2 | John       | Rambo     | [email protected]   |
|  3 | Clark      | Kent      | [email protected]   |
|  4 | John       | Carter    | [email protected]  |
|  5 | Harry      | Potter    | [email protected] |
+----+------------+-----------+----------------------+

Kode PHP dalam contoh berikut memilih semua data yang disimpan dalam tabel orang (menggunakan karakter asterisk (*) di tempat nama kolom memilih semua data dalam tabel)

Penjelasan Kode (Procedural style)

Pada contoh di atas, data yang dikembalikan oleh fungsi mysqli_query() disimpan dalam variabel $result. Setiap kali

2. Nilai penghitung loop ini menentukan berapa kali loop harus dijalankan

Bagaimana cara mendapatkan daftar tabel database di php?

Kita dapat menampilkan daftar tabel yang ada di database dengan menggunakan fungsi mysql_list_tables() . Koneksi harus dibuat sebelum pemanggilan fungsi ini. Pointer hasil yang dikembalikan oleh fungsi ini digunakan oleh fungsi mysql_tablename() untuk menampilkan nama tabel.

Bagaimana cara mengambil data dari database di php dan ditampilkan di tabel?

php $koneksi=mysql_connect('localhost', 'root', 'password');

Bagaimana cara mendapatkan data dari database di php?

Ambil atau Ambil Data Dari Basis Data di PHP .
PILIH nama_kolom DARI nama_tabel
$query = mysql_query("pilih * dari namatabel", $koneksi);
$koneksi = mysql_connect("localhost", "root", "");
$db = mysql_select_db("perusahaan", $koneksi);
$query = mysql_query("pilih * dari karyawan", $koneksi);

Bagaimana cara mendapatkan semua tabel dari MySQL di php?

Sekarang kita akan menunjukkan cara mengaitkannya dengan kode PHP untuk menampilkan semua tabel database MySQL. Jadi, pertama kita harus connect ke database. Setelah ini, kita membuat variabel $showtables yang menanyakan database untuk semua tabel. Setelah ini, kita menggunakan while loop ke low melalui semua tabel .
