What common issue arises when using the ssh2_connect function with PHP 7.2 compared to PHP 5.6?

When using the ssh2_connect function with PHP 7.2, a common issue that arises is the lack of support for the ssh2 extension in PHP 7.2 by default. To solve this, you need to manually install the ssh2 extension for PHP 7.2 using PECL.

// Check if the ssh2 extension is loaded
if (!extension_loaded('ssh2')) {
    // Install the ssh2 extension for PHP 7.2
    if (!defined('SSH2_STREAM_STDIO')) {
        define('SSH2_STREAM_STDIO', 1);
    }
    pecl_install('ssh2');
    echo "SSH2 extension installed successfully.";
}
