php - Insert results of multiple tables into one json_encode() -


excuse language mistakes, speak french.

i did research on site , elsewhere, have found didn't solve problem.

i doing site people can post stories. i'm working on page author should able see stories , chapters of each of them.

i query on 2 tables titles of stories , chapters. have table "stories" in there title , summary of each story (and other stuff id , date of publication). , table called "chapters", in there title of each chapter , id of story belong.

i retrieve these items later in html, have this:

story title 1

chapter 1

chapter 2

so json_encode () jsonlint said json invalid. php new me, began learn i'm not writing code correctly.

here code:

<?php session_start(); require_once('connexion_db.php');  if($db=connect()){     $userid = $_session['id'];      $arr = array();      $reqrecits = $db->query('select titre, id recits user_id = '.$userid.'');     $resrecits = $reqrecits->fetchall(pdo::fetch_assoc);      foreach ($resrecits $r){         $recitid = $r['id'];         $recittitre = $r['titre'];          $reqchapitres = $db->query('select id, titre_chapitre chapitres recit_id = '.$r['id'].'');         $reschapitres = $reqchapitres->fetchall(pdo::fetch_assoc);          foreach ($reschapitres $c){             $chaptitre = $c['titre_chapitre'];         }          $arr = array('titre'=>$recittitre,'chapitre'=>$chaptitre);         echo json_encode($arr, json_unescaped_unicode);     }  }else{     echo "bdd non connectée."; } ?>

i tested method proposed here, result worse. don't know :(

thanks help!

it seems you'd want inner loop go more this:

$chaptitre = array(); foreach ($reschapitres $c){   $chaptitre[] = $c['titre_chapitre']; }

so resulting json include chapter titles.

also, stands, you're listing series of unconnected json objects, should single array legal json object.

foreach ($resrecits $r){     $recitid = $r['id'];     $recittitre = $r['titre'];      $reqchapitres = $db->query('select id, titre_chapitre chapitres recit_id = '.$r['id'].'');     $reschapitres = $reqchapitres->fetchall(pdo::fetch_assoc);      $chaptitre = array();     foreach ($reschapitres $c){       $chaptitre[] = $c['titre_chapitre'];     }      $arr[] = array('titre'=>$recittitre,'chapitre'=>$chaptitre); }  echo json_encode($arr, json_unescaped_unicode);

will collect them , output list.

[   {      'titre': 'title 1',     'chaptitre': ['chapter 1', 'chapter 2']   },   {      'titre': 'title 2',     'chaptitre': ['chapter 1', 'chapter 2', 'chapter 3']   }, ]

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).
