call php file from javascript -


hi have searched web can't work. i'm trying call file databaseupdated.php (placed in same folder index.php file) function called every 10 seconds.

if place following in index.php

<script type='text/javascript'>updateboolean();</script>;

the function runned thats not problem, problem php file not read.

the file databaseupdated.php

<body> <?php  echo ("<script type='text/javascript'>updateboolean();</script>;");  ?> </body>

and here functions in javascript

 $(document).ready(function(){         setinterval(function() {         $.get("databaseupdated.php");//can't work obvious reason (and yes have jquery working)?         return false;                 }, 10000);     });        function updateboolean(){         alert("database updated");         document.location.reload(true);     }

thanks in advance =)

_________________________________________________________________________________________

when do

alert(data); in below function result image show

$(document).ready(function(){             setinterval(function() {                $.get('databaseupdated.php', function(data) {                alert('load performed.');                alert(data);                eval(data);             });         }, 5000);    });

enter image description here

but "eval(data)" doesn't seem work

$.get("databaseupdated.php"); // return contents of file scripts in file not executed. execute them need eval(). try  $.get('databaseupdated.php', function(data) {        eval(data);     });

also, may require change php file following:

echo ("updateboolean();");

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).
