PHP - PHP en Javascript

Hola!
Tengo un menu armado enteramente en javascript, queria saber si se puede colocar variables de php en el javascript....para aclarar les doy el ejemplo
<
script language="JavaScript1.2">
<!--
stm_bm(["menu1c0b",700,"","blank.gif",0,"","",0,0,19,19,1000,1,0,0,"","",83886139,0,1,1,"default","hand",""],this);
stm_bp("p0",[1,4,0,0,1,3,7,7,100,"",-2,"",-2,40,2,3,"#999999","#000000","",0,0,0,"#000000"]);
stm_ai("p0i0",[0,"Sistema de Puntaje","","",-1,-1,0,"","_self","","","","",7,13,0,"","",0,0,0,0,1,"#BDD888",0,"#000000",0,"","",3,3,1,1,"#AECC74","#AECC74","#000000","#FFFFFF","bold 8pt Verdana","bold 8pt Verdana",0,0],150,0);
stm_aix("p0i1","p0i0",[0,"Mis Datos","","",-1,-1,0,"editacontacto.php?ID_Contacto=

En cualquier parte de tu archivo .php puedes colocar codigo php siempre y cuando esten dentro de sus tags

<?php ?>
