get the md5 hash of a binary file in php

To get the md5 hash of a binary file in PHP, you can use the hash_file function. This function calculates the hash value using the specified algorithm for a given file.

main.php
$file_path = '/path/to/binary/file';
$md5_hash = hash_file('md5', $file_path);
echo $md5_hash;
95 chars
4 lines

In the code above, the $file_path variable holds the path to the binary file you want to calculate the md5 hash for. The hash_file function takes two parameters: the algorithm to use for calculating the hash (in this case, 'md5'), and the path to the file.

After the hash_file function is called, the $md5_hash variable will contain the md5 hash of the binary file. This value can be used for various purposes, such as verifying the integrity of the file.
