curl multi update

I need updates to a curl function, which is ATTACHED: Current function is passed array of url's and uses curl multi to download and save page to file. My webserver can handle 250 curl requests at once. If you want to rewrite function, is ok as long as it does what it currently shows and the new items below. Basically needs to receive urls and etag or last modified date and save page if newer than last etag or last modified data or update db with error code if [login to view URL] items below, I need the error code or date or etag etc to be in a variable somehow so that I can insert it into database using id field. Just insert comment before and after where need to insert mysqli statement and show what the variable is called (probably obvious but maybe not) like //insert mysqli here to update etag or last_modified date when newer than what is in database //$http_code //is the variable to return the error code if an error exists for a specific url request //$etag //is the variable to return the current etag //end of insert mysqli I need the following added to the function: 0. function currently receives array of id=>url, instead needs to pass following fields in row from query result (id,url,etag,last_modified). 1. before it creates new file, check to see if error from header if > 400 code, should not create file and should give code to update database and fclose if fopen was used, don't save page and close everything for this url. If bad request like bad url etc, must do same thing except return error code. Also if ($content_length == 0) should return error "99999". 2. Read header info and if ETag == $db['etag'] don't save page and close everything for this url. if !ETAG then if Last-Modified == $db['last_modified'] don't save page and close everything for this url. 3. at end of script before it returns from last item in array needs to update database to change satus so just put mysqli comment block for it. 4. Add to enable http proxy as option, I will probably just use one version for db_result that don't need proxy and then one version for db_result that requires proxy and sleep(15) if from same host; comment this entire block so I know what to comment out for db_result where no proxy required. 5. set options as an array instead of individual curl_setopt if possible, add cookiefile => cookie.txt. Needs to handle https also. max_redirects 3,
