Overview

PHP Image Lib is a lightweight library for validating and manipulating images in a simple and consistent way.
It provides essential tools for checking image integrity, validating binary content, resizing images, and inspecting image properties.

The library allows you to:

• Validate whether a file is a valid image
• Verify the integrity of image binary data
• Resize images with optional cropping and forced resizing
• Validate image dimensions before processing
• Detect and retrieve image file extensions

With its straightforward API, this library is ideal for handling user-uploaded images, enforcing image constraints, generating thumbnails, and preparing images for web applications.

This library helps ensure image safety and consistency while keeping image processing fast and easy to integrate.

To see a working example, open index.php on your server.

Usage

include __DIR__ . "/lib/ImageHandler.php";

$ImageHandler = new ImageHandler();

$status = $ImageHandler->isImageValid($file_path); //checks if a file is an image
$status = $ImageHandler->isImageBinaryValid($file_path); //checks if a file is an binary image
$status = $ImageHandler->imageResize($src_path, $dst_path, $width, $height, $crop = false, $force_resize = false); //resizes an image file to another file
$status = $ImageHandler->areImageMeasuresValid($file_path, $width, $height, $crop = false); //check if images are valid, like if we are cropping a file, then the desired dimensions must be smaller than the current image dimensions.
$extension = $ImageHandler->getFileExtension($file_path); //get the image file extension
