PHPda SQL so'rov orqali sonini hisoblash

COUNT buyrug'i yordamida tanlovdagi qatorlar sonini hisoblash mumkin.

Keling, masalan, jadvaldagi barcha foydalanuvchilarni hisoblaylik:

php<?php
  $query = "SELECT COUNT(*) FROM users";
?>

Endi esa, maoshi 900 ga teng bo'lgan hammadagi sonini hisoblaylik:

php<?php
  $query = "SELECT COUNT(*) FROM users WHERE salary=900";
?>
