Type Casting to Integers in PHP

Let's say, for example, we have a string with digits:

php<?php
  $test = '1';
  var_dump($test);
?>

Let's convert it to an integer. For this, we will use the special command int, like this:

php<?php
  $test = (int) '1';
  var_dump($test); // will output 1 - a number
?>

You can use the type casting command directly in the function call:

php<?php
  var_dump((int) '1');
?>

You can convert the value of a variable:

php<?php
  $test = '1';
  var_dump((int) $test);
?>

php<?php
  $test = '12345';
?>
