Brightness and Contrast values apply changes to the input image. They are not absolute settings. A brightness or contrast value of zero means no change. Positive values increase the brightness or contrast and negative values decrease the brightness or contrast.
Where do I begin? Make sure you assign your constructor a state public, private, or protected. Where are all these extra properties coming from? And its not defined as a class property, so I can't even be sure this is supposed to be here. The class you provide does not extend a parent class, so it isn't from there.
It just appeared in invoke out of no where.
It looks like you've either copy-pasted this all together, or had a collaboration with someone else and you've crossed your naming schemes. They should be renamed as such or vice-versa. It is probably easier to rename where they are defined, less to change, but up to you.
If it returns something other than a boolean, then it is doing too much and needs to be separated into multiple functions.
Arrays and loops are your best friend for repititive code. Dry is a good concept unless taken to extreme I'll add the loop in as a matter of preference even though a tad bit less efficient. It also automates similar tasks for any parameters you wish to throw at it so that if that task should ever need to change, you'll only ever have to do so once.
Or should you ever wish to add to it, you only need to add a parameter to an array. Where did you hear that DRY is inefficient? I admit abusing it could get ridiculous, but you have to go out of your way to accomplish that.
Anyways, here's what I have for your update. You still have that issue with variables and properties appearing out of thin air. Though I, personally, would switch that around. I like imagining my variables like this to be asking a question "validated?
But thats a preference. Another thing I just noticed. You are declaring your properties like so: First of all, these are cosidered bad form, mostly because they are impossible to track and make your code unuseable by anyone but you.
Not really, but pretty damn close, not even IDE's can track these. Here it is explained in code, hopefully more clear. You have a couple of really long statements that could be made more legible. There are a few ways you can do this. The simplest is to bring the parameters out of the method call and convert them to variables in the local scope.
This is pretty common and helps clean up code quite a bit. PHP does not care about whitespace, so you can drop long statements like this to new lines and indent to your hearts content. Those are numbers that appear out of thin air and could mean anything. Much like those variable variables I mentioned earlier, they are almost impossible to track down.
To you, as the author, you probably know what these are at a glance. But to someone reading your code for the first time, they will not have a clue. This could even be you in a few months after you've started working on other projects. Take a look at the code above.
Those zeroes "0" and empty strings '' don't mean anything. Declare them and set them as variables so people know what they do.Factory method to create a new Amazon S3 client using an array of configuration options. I would like to validate that an array has and only has "a", "b", and "c" as associate keys, and that the values are either integers or either NULL or 0 (what ever is easier).

Sep 17, · I can't believe I haven't come across this in all of my PHP programming (or my brain is currently locked) I need to delete an array from an array that i'm traversing through with a foreach.
The tree is loaded with the URL 'torosgazete.com'. The child nodes to be loaded dependent on the parent node state. When expand a closed node, if the node has no child nodes loaded, it will send node id value as the http request parameter named 'id' to server via the URL defined above to retrieve child nodes.
