We can implement ckeditor with image uploading in PHP simply. if you want to use ckeditor in your PHP project and you also want to add file uploading as well then you can do easily to follow bellow step.
In this example i use ckeditor with KCFinder for image uploading. KCFinder through we can file upload easily using their api. If you don't know about ckeditor and KCFinder then no issue you can add simple way.
Now, i will give you few step to set ckeditor with file uploading and you will easily apply this. this is a very simple to browse your image, file etc upload.
I was working on my project and implementing KCEditor and CKFinder (the free one) with image upload, but when i tried to upload image i found error like "you don't have permissions to upload files".
So, i though maybe issue for folder permission because i used ubuntu OS. i gave whole ckfinder folder give full permission 777 and also give ckeditor folder too. but same error. At last i found how to solve it. So if you have also fetch this error then you have to open config.php file in conf folder of ckfinder and disabled equal to give false.
