How to Convert a String to a Number in PHP
Use Type Casting
As we know PHP does not require or support explicit type definition in variable declaration. However, you can force a variable to be evaluated as a certain type using type casting.
Let's try out the following example to understand how this works:
<?php
$num = "2.75";
// Cast to integer
$int = (int)$num;
echo gettype($int); // Outputs: integer
echo $int; // Outputs: 2
// Cast to float
$float = (float)$num;
echo gettype($float); // Outputs: double
echo $float; // Outputs: 2.75
?>
