php - Which way is better Extending classes or keeping them separate and creating multiple objects? -

can let me know, when using php classes, best way given kind of scenario : have 2 classes , b, both have different functions both used on same page.

if keep both separate have create 2 objects , use them , if extend have create 1 object. best way? or there other way situation?

you should extend php class if want inherit variables or functions parent. e.g., square, circle, , triangle classes might extend shape.

from sounds of post 2 separate entities, worth having 2 separate classes. memory consumption having class minimal.
