php getimagesize of dynamically created picture

由 眉间皱痕 提交于 2019-12-13 04:34:27
问题 I am trying to determine if image.php is valid picture file. It may be or may be not because if DB has information about resized picture it is going to be valid - image.php will resize original picture and print it to the screen. There is also alternative - there is no filename information in database and it can result error message or error picture. I'd like to get dimensions of image and if it is width = 0 and height = 0 then print error message. I was trying to do it with getimagesize but

问题 I am trying to use getimagesize with URL and with http everything is fine. However when trying to use function on https url I am getting "Read error" Notice and false as result. I checked and I have OpenSSL 0.98 installed on the server (so it should be working with https as well). I know that I can download the image first and then use it but it seems to me like this should work and that I am missing something. Could you please provide me with some solution (other than downloading the image

问题 This question already has answers here : How to scrape websites when cURL and allow_url_fopen is disabled (4 answers) Closed 6 years ago .

Automatically adding width and height attributes to <img> tags with a PHP function

由 耗尽温柔 提交于 2019-12-10 20:44:45
问题 What I want is a function I can run on user input that will intelligently find and add the width and height attributes to any <img> tag in a blob of HTML so as to avoid page-reflowing issues while images load. I am writing the posting script for a PHP forum, where a user's input is sanitised and generally made nicer before writing it to the database for later display. As an example of what I do to make things nicer, I have a script that inserts alt attributes into images like so: Here are two
