Sample PHP Code

<?php
include_once 'path_to_phpjasperxml/PHPJasperXML.inc.php';//in this case, phpjasperxml is your submodule from github

$PHPJasperXML = new PHPJasperXML("en","TCPDF"); //if export excel, can use PHPJasperXML("en","XLS OR XLSX"); 
//$PHPJasperXML->debugsql=true;	
$PHPJasperXML->arrayParameter = array('para1'=>'1','para2'=>'2');
$PHPJasperXML->load_xml_file('file1.jrxml'); //if xml content is string, then $PHPJasperXML->load_xml_string($templatestr);
//$PHPJasperXML->sql = $sql;  //if you wish to overwrite sql inside jrxml
$dbdriver="mysql";//natively is 'mysql', 'psql', or 'sqlsrv'. the rest will use PDO driver. for oracle, use 'oci'

$PHPJasperXML->transferDBtoArray(DBSERVER,DBUSER,DBPASS,DBNAME,$dbdriver);
$PHPJasperXML->outpage('I');  //$PHPJasperXML->outpage('I=render in browser/D=Download/F=save as server side filename according 2nd parameter','filename.pdf or filename.xls or filename.xls depends on constructor');
