-    errors through the traditional error reporting mechanism used by PHP 5,
-    most errors are now reported by throwing Error exceptions."

-
-    Skip this check for PHP 5.6 in order to support PHP 7.x
-
-    Catch Exception and Error separately to support both versions.
-
-    Example:
-
-    <code>
-		try {
-			// Run your code here
-		} catch(Error $e) {
-			// Handle errors (PHP 7.0+)
-		} catch(Exception $e) {
-			// Handle exceptions (PHP 5.6+)
-		}
