In this step, first, we need to get the image type by using the PHP function getimagesize(), which is used for getting an entire list of image properties, including width, height and etc. For example, imagecreatefromjpeg(), imagecreatefromgif(), imagecreatefrompng(), used to get the resource identifier for JPEG, GIF and PNG images. These functions are used appropriately based on the type of image given for resizing. In PHP, there are various functions to get an image file resource id. Save resized image into the given target location.įor working on the given image file to be resized, we need to get the resource identifier for reference, as we have done while working with files after getting file resource, or like, getting directory handle to perform PHP directory functions.Get resource id for target image layer.Get the image resource id for the source image.So, a combination of such functions is used to obtain the following steps, which will result in successful image resizing through PHP programming. In PHP, resizing an image, it can be achieved by using a set of PHP functions to create a new image from scratch, with the given dimensions, in which the original image is expected to be resized. If not, we need to resize these images, accordingly. While displaying images for our websites, it is important to ensure that it could be set within our layout boundary.
