How to adpated a javascrip with php...

Hi, I have a Javascript that I like to use with PHP/MYSQL, But I don't know how to mix the two... <SCRIPT LANGUAGE = "JavaScript"> bName = navigator.appName; bVer = parseInt(navigator.appVersion); if ((bName == "Netscape" && bVer >= 3) ||

       (bName == "Microsoft Internet Explorer" && bVer >= 4)) br = "n3";

else br = "n2"; if (br == "n3") { boardNum = 0; boardSpeed = 4000; billboards = new Array(); billboards[0] = new Image(); billboards[0].src = "$x"; billboards[1] = new Image(); billboards[1].src = "$x"; billboards[2] = new Image(); billboards[2].src = "$x"; billboards[3] = new Image(); billboards[3].src = "$x"; billboards[4] = new Image(); billboards[4].src = "$x"; billboards[5] = new Image(); billboards[5].src = "$x"; billboards[6] = new Image(); billboards[6].src = "$x"; billboards[7] = new Image(); billboards[7].src = "$x"; } [I like to make $x to be called from the database...] function rotateBoard() { document.billboard.src = billboards[boardNum].src; if (boardNum < billboards.length - 1) { boardNum++; } else { boardNum = 0; } } function jumpBillboard() { window.location.href = url[boardNum]; } </SCRIPT> Thanks for any help you can give...
