Thread: Resize Upload Images in PHP

Hi. I am working in live project where I use PHP programming language. In my project one form is there in that form image upload function is there. Using this function user upload their image. I want Resize Upload Images. It is possible? If possible please give me proper code for that. Thank you.

PHP has the capacity to upload files such as documents or images using the multiple form-data protocol. Here’s the code to convert, scale and write out a scaled JPG image.

Code:

/*== where storing tmp img file ==*/
 = tempnam("/tmp" "MKPH");
 = "/scaled.jpg";

/*== CONVERT IMAGE TO PNM ==*/
if ( == "jpg") { system("djpeg  >"); } 
else { echo("Extension Unknown. Please only upload a JPEG image."); exit(); } 

/*== scale image using pnmscale and output using cjpeg ==*/
system("pnmscale -xy 250 200  | cjpeg -smoo 10 -qual 50 >");
