php function to resize an image
Article Introduction：The most direct way to resize images using PHP is to use the GD library. 1. Load the original image; 2. Create a new canvas of the specified size; 3. Copy and resample the original image onto the new canvas. If the aspect ratio needs to be maintained, the target size is dynamically adjusted by calculating the aspect ratio. After the adjustment is completed, you can choose to output the image to the browser or save it to a file and use imagedestroy() to free up memory. When processing PNG images, transparent channel support is required. Make sure the GD library is enabled and verify the file type and size before processing uploaded images.

PHP base64_encode and base64_decode example
Article Introduction：Base64 encoding is used in PHP to convert binary data into string format for easy transmission or storage. 1. The base64_encode() function is often used to process the transmission of images, file contents or special characters, such as embedding PNG icons into HTML dataURI to display; 2. The base64_decode() function is used to restore encoded data, such as decoding user information in the API interface; 3.
