How can PHP_Compat from PEAR be used to address compatibility issues between PHP versions?

PHP_Compat from PEAR can be used to address compatibility issues between different PHP versions by providing functions and constants that may not be available in older versions of PHP. This allows developers to write code that can run on multiple versions of PHP without having to worry about compatibility issues. 

require_once 'PHP/Compat.php';
PHP_Compat::loadFunction('array_combine');
$array1 = array('a', 'b', 'c');
$array2 = array(1, 2, 3);
$result = array_combine($array1, $array2);
print_r($result);
