PHPda kasr sonlarga majburiy o'zgartirish

Endi bizda kasr sonli qator bo'lsin:

php<?php
  $test = '1.2';
  var_dump($test);
?>

Ushbu qatorni songa o'zgartirish uchun float buyrug'idan foydalaning:

php<?php
  $test = (float) '1.2';
  var_dump($test); // 1.2 ni chiqaradi
?>

php<?php
  $test = '12.345';
?>
