php - Encode to JavaScript object, function get replaced -


i have issue on highcharts project , charts options saving in database . printing on chart using following code . let me explain issue using sample code .

echo 'var options69 = '.$highcharts_json_options; echo php_eol; echo 'var options69_func = '. json_encode( $functions); echo php_eol;  echo '$(document).ready(function() {'; echo php_eol; echo '      chart69 = new highcharts.chart(                  $.extend(true, options69, options69_func)              );'; echo php_eol; echo '});';

the issue $functions not converts correct javascript object . here example of code of $functions 

$functions = array(     'chart' => array(         'events' => array(             'click' => "function(){inboxmenu(this.options);}"         )      ),     'tooltip' => array(         'formatter' => "function(){             return '<b>'+ this.series.name + ':</b>'+ this.y;         }"     ) );

currently, json_encode( $functions) outputs 

var options69_func = {     "chart": {         "events": {             "click": "function(){inboxmenu(this.options);}"         }     },     "tooltip": {         "formatter": "function(){return '<b>'+ this.series.name + ':<\/b>'+ this.y;}"     } }

but need value var options69_func like

var options69_func = {     "chart": {         "events": {             "click": function(){                 inboxmenu(this.options);              }         }     },     "tooltip": {         "formatter": function(){             return '<b>'+ this.series.name + ':<\/b>'+ this.y;         }     } }

then chart click event or formatter works .. these values coming dynamically server database . add callback function json_encode ?

i added php generated js code http://jsfiddle.net/u9w6x/

i won't using eval function.. on client side

after options69_func, if want excute function "click", can try this: eval('('+options69_func.tooltip.click+')'+'();');

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
