How do you convert a string to an integer in PHP with Example?

Hello Friends Today, through this tutorial, I will tell you How do you convert a string to an integer using PHP With Example? In PHP, you can convert a string to an integer using the `(int)` casting or by using the `intval()` function. Here’s an example demonstrating both methods:

<?php
// Using (int) casting
$stringNumber = "123";
$intValue = (int)$stringNumber;
echo $intValue; // Output: 123

// Using intval() function
$stringNumber = "456";
$intValue = intval($stringNumber);
echo $intValue; // Output: 456
?>

Both `(int)` casting and `intval()` function convert a string representing a number to an integer. However, it’s worth noting that `(int)` casting is generally faster, while `intval()` allows more options such as specifying the base for conversion.
