imageresoulution() is an inbuilt function in PHP that is used to get or set the resolution of an image in dots per inch. If no optional parameters are given, then the current resolution is returned as an indexed array. If one of the optional parameters is given, then it will set both the width and height to that parameter.The resolution is only used as meta information when the images are read from and written to formats supporting this kind of information (currently PNG and JPEG). It does not affect any drawing operations. The 96 DPI (dots per inch) is the ... Read More
