In PHP, how do I hash strings in a memory-efficient way?

This guide explains how to hash strings in PHP in a memory-efficient manner, leveraging built-in functions to ensure performance and security.

To hash a string in a memory-efficient way using PHP, you can utilize the `password_hash()` and `password_verify()` functions. These functions are designed for securely hashing passwords but can also be used for general string hashing. Here's an example:

<?php // Original string $string = "Hello, world!"; // Hash the string securely $hashedString = password_hash($string, PASSWORD_DEFAULT); // Output the hashed string echo "Hashed string: " . $hashedString; // Verify the hashed string if (password_verify($string, $hashedString)) { echo "String matches the hashed value."; } else { echo "String does not match the hashed value."; } ?>
