Checking if URL of image is valid or exist.

[andyhajime]

Hello all,

 

I'm currently doing this Facebook connect module for my website. With the FBconnect, it creates a user profile on my mysql, which stores only the Facebook userid, the full name, and the thumbnail url of this user.

 

Currently the code works well except for this 'image url checking'.

this is my fb profile image url: http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs349.snc4/41540_772137439_5612219_q.jpg

 

when I've added a 'XXX' at the back ( http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs349.snc4/41540_772137439_5612219_qXXX.jpg ). It returns a blank instead.

 

On Facebook, some accounts are not genuine and they might the deleted sooner or later. So I'm trying to figure out a php script or functions which detect if the image is not the 'XXX' version.

 

I've tried using getimagesize() or file_get_contents() but still won't work.

 

any ideas?

does getimagesize() return anything? if it returns a low value you could tell your script only to display the image if its over a certain value

Could try

<?php

$info = @getimagesize("http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs349.snc4/41540_772137439_5612219_q.jpg");
if	(isset($info["mime"]))
echo "yay it exists" . "<br />";
else
echo "nope it doesnt exist" . "<br />";


$info = @getimagesize("http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs349.snc4/41540_772137439_5612219_qXXX.jpg");
if	(isset($info["mime"]))
echo "yay it exists" . "<br />";
else
echo "nope it doesnt exist" . "<br />";
