' need distinguish them. intuitive thoughts use port number in ip packet. if have other suggestion, welcome. i have found the similar question here , not using apache now. , may hard me config maybe causing other more complex questions. might make simple question com

i using jnetpcap analyze pcap files. know how addresses when encounter ip header if(packet.hasheader(ip)&&packet.hasheader(tcp)&&tcp.flags_syn()) { sip = packet.getheader(ip).source(); sourceip = org.jnetpcap.packet.format.formatutils.ip(sip); but don't know how address when have icmp header. tried this else if(packet.hasheader(icmp)) { sip=packet.getheader(icmp).source(); sourceip = org.jnetpcap.packet.format.formatutils.ip(sip); but apparently, isn't valid. ideas? thank in advance update: used if(packet.hasheader(ip, 1)) { sip=ip.source(); sourceip = org.jnetpcap.packet.format.formatutils.ip(sip);} but got error: exception in thread "main" java.lang.nullpointerexception @ diplomatiki.ex2.main(ex2.java:83) line 83 contains command: sip=packet.getheader(ip,1).source(); i tried hit mark's advice, , added system.out.println(packet.getstate().todebugstring());

there object in php named $item , , in object have properties of title , title_cn, title_tw and create function auto generate properties based on language, coding this: <?= $item->title . set_lang(); ?> and function: function set_lang() { $ci =& get_instance(); $lang = $ci->session->userdata('site_lang'); if ($lang == "english") { return ""; } else if ($lang == "zh_tw") { return "_tw"; } else if ($lang == "zh_cn") { return "_cn"; } } however, name not generated correctly, $item->title append string of lang code, e.g. my title 1234_tw, titleabc_cn etc... how dynamic generate properties ? fo helping you should first concatenate $item->title onto set_lang() , place in variable. you can use variable call right property on obj. example $itemlangtitle = $item->title . set_lang(); echo $item->$itemlangtitle

i have array , need pass each element of array parameters function. say: $var = array("var2","var3","var4"); //pass each element new parameter function call_to_function ($var2, $var3, $var4); //however, if number of array element change can $var = array("var2","var3"); call_to_function ($var2,$var3); the problem here is, how build dynamic number of parameters , call function. use: php function mysqli_stmt::bind_param , takes multiple parameters. , need derive parameters arrray. is there way it? this should work you: first need create array references corresponding variables. can foreach loop below: foreach($var $v) { $bindvalues[] = &$$v; } after can use call_user_func_array() call function bind variables. here depends if use procedural or oop style: procedural: call_user_func_array("mysqli_stmt_bind_param", array_merge([$stmt, $types], $bindvalues)); oop: call_user_func_arr
