PHPda SQL so'rov orqali sonini hisoblash
COUNT buyrug'i yordamida
tanlovdagi qatorlar sonini hisoblash mumkin.
Keling, masalan, jadvaldagi barcha foydalanuvchilarni hisoblaylik:
<?php
$query = "SELECT COUNT(*) FROM users";
?>
Endi esa, maoshi
900 ga teng bo'lgan hammadagi sonini hisoblaylik:
<?php
$query = "SELECT COUNT(*) FROM users WHERE salary=900";
?>
