How to Use sha1() Function in PHP 8.2 With Example?

Support PHP Version: PHP 7.1, PHP 7.2, PHP 7.3, PHP 7.4, PHP 8.0, PHP 8.1, PHP 8.2, PHP 8.3 With Latest All Version Support.

In PHP 8.2, the `sha1()` function remains the same as in previous versions. It is used to calculate the SHA-1 hash of a string. Here’s how you can use it with an example:


// String to hash
$string = "Hello, world!";

// Calculating SHA-1 hash
$hash = sha1($string);

// Output the hash
echo "SHA-1 hash of '$string' is: $hash";


When you run this script, it will output something like:

SHA-1 hash of 'Hello, world!' is: 2ef7bde608ce5404e97d5f042f95f89f1c232871

This hash can be used for various purposes like data integrity verification, password hashing (although it’s not recommended for this purpose due to its vulnerability to collision attacks), and more.
