How do I convert a string to a number in PHP?

Question

I want to convert these types of values, `'3'`, `'2.34'`, `'0.234343'`, etc. to a number. In JavaScript we can use `Number()`, but is there any similar method available in PHP? Input Output '2' 2 '2.34' 2.34 '0.3454545' 0.3454545

Answer 1

You can cast any compatible string to int or float.

Here's an example:

<?php

$stringNumber = "20.1";

$StringTofloat = (float)$stringNumber;

$stringToNumber = (int)$stringNumber;

print_r($stringToNumber); // 20

print_r("\n");

print_r($StringTofloat); // 20.1

?>
