PHP - Helper Functions

helpers.php

<?php

if (! function_exists('join_paths')) {
    /**
     * Join two or more paths together
     */
    function join_paths(string ...$paths): string
    {
        $first = array_shift($paths);

        $paths = array_filter(
            array_map(fn (string $p) => trim($p, DIRECTORY_SEPARATOR), $paths)
        );

        return join(DIRECTORY_SEPARATOR, [rtrim($first, DIRECTORY_SEPARATOR), ...$paths]);
    }
}

if (! function_exists('unzip')) {
    /**
     * Unzip the given filename
     *
     * This function will attempt to unzip the given zip file name into the given location, but if the location
     * is not provided, we'll use the file directory.
     *
     * @param string $filename The file name of the ZIP file
     * @param ?string $to The location where to extract the content
     * @return void
     */
    function unzip(string $filename, string $to = null): void
    {
        if (! extension_loaded('zip')) {
            throw new \RuntimeException('Extension [ext-zip] not found');
        }

        $zip = new \ZipArchive();
        $to ??= dirname($filename);

        try {
            $zip->open($filename);

            $zip->extractTo($to);
        } finally {
            $zip->close();
        }
    }
}

These are the most common functions I use in my projects, and because I don't to create a package just for helper functions, I decided to create this Gist to keep track of them.
