Referencing PHP from an ext JavaScript file

[Richlad]

I'm having some trouble trying to get my tweets on the header of my site using an ext PHP file, referenced from a JavaScript tag - I have included the header reference in the PHP file and output as last line is javascript encompassing the echo. \[code\]<?phpHeader("content-type: application/x-javascript");//Get Latest Tweetfunction latest_tweet($username,$tweetnumber){ $url = "http://search.twitter.com/search.atom?q=from:$username&rpp=10"; $xml = simplexml_load_file($url); $tweettitle = $xml->entry[$tweetnumber]->title; $mytweet = $xml->entry[$tweetnumber]->content; $firstChar = substr($tweettitle, 0, 1); //Exclude @ replies if($firstChar == "@"){ //If this tweet is an @ reply move on to the previous one while ($firstChar == "@"){ $tweetnumber++; $tweettitle = $xml->entry[$tweetnumber]->title; $mytweet = $xml->entry[$tweetnumber]->content; $firstChar = substr($tweettitle, 0, 1); if($firstChar != "@"){ //If the previous tweet is not an @ reply output it return $mytweet; } } } else { //If first tweet is not an @ reply output it return $mytweet; }}//End Get Latest Tweet//outputecho "document.write(latest_tweet('mikedeveloper', 0))";?>\[/code\]
