Thinkphp processes base64 images

{Code...} How to apply the {code...} to the example given by tp, and how to use thinkphp to process the $ result? For example, I want to change the width and height of a piece and then upload it to the server. Thank you!

$ Url = ''// network Image address; $ curl = curl_init ($ url); curl_setopt ($ curl, CURLOPT_URL,''); curl_setopt ($ curl, CURLOPT_REFERER, ''); curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1); $ result = curl_exec ($ curl); // header ('content-type: image/JPEG '); // echo $ result; return $ result;

How to apply the example given by tp

$ Image = \ think \ Image: open ('. /image.png '); // returns the image width $ width = $ image-> width (); // returns the image height $ height = $ image-> height (); // the type of the returned image $ type = $ image-> type (); // The mime type of the returned image $ mime = $ image-> mime (); // returned image size array 0 image width 1 image height $ size = $ image-> size ();

How can I use thinkphp to process the $ result? For example, I want to change the width and height of a piece and then upload it to the server.
Thank you!

This is the native package I installed on the internet. for your reference, it is actually very simple. it is to decode the base64 bit and save it locally.
I will generate the following code.
As for the image size you mentioned, I am using it. you can either use the js plug-in before Upload to allow users to complete the upload, or use PHP to operate the image after you generate it locally. Only local files can be operated on by the server.

/*** Save the 64-bit encoded image */function saveBase64Image ($ base64_image_content) {if (preg_match ('/^ (data: \ s * image \/(\ w + ); base64,)/', $ base64_image_content, $ result) {// Image suffix $ type = $ result [2]; // save location -- image name $ image_name = date ('his '). str_pad (mt_rand (1, 99999), 5, '0', STR_PAD_LEFT ). ". ". $ type; $ image_url = '/uploads/image /'. date ('ymmd '). '/'. $ image_name; if (! Is_dir (dirname ('. '. $ image_url) {mkdir (dirname ('. '. $ image_url); chmod (dirname ('. '. $ image_url), 0777); umask ($ oldumask);} // decodes $ decode = base64_decode (str_replace ($ result [1], '', $ base64_image_content )); if (file_put_contents ('. '. $ image_url, $ decode) {$ data ['code'] = 0; $ data ['imagename'] = $ image_name; $ data ['URL'] = $ image_url; $ data ['MSG '] =' saved successfully! ';} Else {$ data ['code'] = 1; $ data ['imagename'] = ''; $ data ['URL'] = ''; $ data ['MSG '] = 'image saving failed! ';}} Else {$ data ['code'] = 1; $ data ['imagename'] = ''; $ data ['URL'] = ''; $ data ['MSG '] = 'base64 image format error! ';} Return $ data ;}

Save images as image.png
Use the image class of thinnkphp to delete the temporary image.
