How Can I Convert a String to a Number in PHP?

Converting a String to a Number in PHP

Unlike JavaScript's Number() method, PHP lacks a direct function to convert strings to numbers. However, PHP allows for type coercion in various situations.

Type Casting for Explicit Conversion

In cases where explicit conversion is required, casting can be employed using the following syntax:

• (int)$string: Converts the string to an integer.
• (float)$string: Converts the string to a floating-point number.

For instance, consider the following conversions:

$num = "3.14";
$int = (int)$num; // Result: 3
$float = (float)$num; // Result: 3.14

PHP's Automatic Type Coercion

In most instances, PHP will automatically coerce types during operations. For example:

$num = "2";
$total = $num + 10; // $total will be 12 (an integer)
