Count image files on remote server

[BuildMyWeb]

i need to count the number of image files on a remote server not in my network.  ive come across a suggestion to use

@getimagesize($img_url)

the above works but is really slow.  anyone able to suggest a better method?

It's probably slow because it's on a remote server, which means it has to retrieve the file first before it can run a function on it.

yes cronix.  ive read that it will always be exceedingly slow to use in this manner.  and makes sense.  hence why im looking for an alternative

Use an appropriate library, not this crappy built-in HTTP stuff.

 

PHP supports cURL which is a well known library for HTTP and other protocols. Make parallel HEAD requests (CURLOPT_NOBODY set to true). This way you just ask the webserver for the response code rather than unnecessarily downloading the actual file content. And the requests don't have to wait for each other.

 

Depending on how exactly the counting works, you may also optimize that.

It seems if you want to "count" it, you could just use CURL like this to only examine the file header and if the status returned is 200 than increment a counter or something.
