In need to get lastmodified date for webpage for other websites in internet via http reponse or through other techniques..

 

I did it something like this:

$conn = @fopen($httpAddress);
$meta = stream_get_meta_data ($conn);

Code (markup):

This returns an array of the metadata, and Last Modified is in a subarray called "wrapper_data" with key 4:

echo $meta['wrapper_data'][4];

Code (markup):

This also contains the words "Last-Modified: ", so you can do:

$dateForHumans = preg_replace('#Last-Modified: #', '', $meta['wrapper_data'][4]);
$LastModified = strtotime($dateForHumans);

Code (markup):

Not sure if that is what you are looking for but works for me. Check the code, cos I copied it from some script of mine, the variable names might be mixed up or something.

 

Wow! I was searching these codes.
