javascript - call a php variable in createmarker function -

-

i'm parsing php xml file , i'm trying put marker in every $item.
error i'm getting : 'uncaught syntaxerror: unexpected string' in these lines

    function createmarker( '<?php echo $item['temp']; ?>',latlng,cold ) { var marker = createmarker( '<?php echo $item['temp']; ?>',latlng,cold );

here code 

    function initialize() {       var mapoptions = {         zoom: 6,         center: new google.maps.latlng( 38.822590,24.653320 )       };       var map = new google.maps.map(document.getelementbyid('map-canvas'),mapoptions);             <?php foreach ( $item_array $item ) : ?>             var latlng = new google.maps.latlng(parsefloat(<?php echo $item['glat']; ?>),                                                 parsefloat(<?php echo $item['glon']; ?>));             if ( '<?php echo $item["temp"] ?>' >= "18 °c" ) {                 alert('<?php  echo $item["temp"]; ?>');                  var marker = createmarker( '<?php echo $item['temp']; ?>',latlng,cold );             }             <?php endforeach; ?>              var cold  = 'weather_icons/pagetos2.png';             function createmarker( '<?php echo $item['temp']; ?>',latlng,cold ) {                 var marker = new google.maps.marker({                 position: latlng,                 map: map,                 icon: cold                 });                 return marker;             }     }     google.maps.event.adddomlistener(window, 'load', initialize);

any ideas how i'm gonna have succesfull call in createmarker function?

just remove first parameter of function createmarker , work perfectly.

function initialize() {   var mapoptions = {     zoom: 6,     center: new google.maps.latlng( 38.822590,24.653320 )   };   var map = new google.maps.map(document.getelementbyid('map-canvas'),mapoptions);         <?php foreach ( $item_array $item ) : ?>         var latlng = new google.maps.latlng(parsefloat(<?php echo $item['glat']; ?>),                                             parsefloat(<?php echo $item['glon']; ?>));         if ( '<?php echo $item["temp"] ?>' >= "18 °c" ) {             alert('<?php  echo $item["temp"]; ?>');              var marker = createmarker(latlng,cold );         }         <?php endforeach; ?>          var cold  = 'weather_icons/pagetos2.png';         function createmarker( latlng,cold ) {             var marker = new google.maps.marker({             position: latlng,             map: map,             icon: cold             });             return marker;         } } google.maps.event.adddomlistener(window, 'load', initialize);

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
