What are common challenges faced when installing Zend Framework in PHP applications?

One common challenge faced when installing Zend Framework in PHP applications is setting up the autoloader correctly to load the necessary classes and files. To solve this issue, make sure to include the Zend Framework library in your project's include path and configure the autoloader to load classes from the Zend namespace.

// Include the Zend Framework library in your project
set_include_path(get_include_path() . PATH_SEPARATOR . '/path/to/ZendFramework/library');

// Configure the autoloader to load classes from the Zend namespace
spl_autoload_register(function($class) {
    if (strpos($class, 'Zend\\') === 0) {
        require str_replace('\\', '/', $class) . '.php';
    }
});
