How to properly encode a multi-dimensional array in php [duplicate] - php

Question

This question already has answers here:
php json_encode not working on arrays partially
(2 answers)
Closed 7 years ago.
I am trying to properly create and encode and array using json_encode php function. The array i am trying to encode is $myarray . From my code if do
$myarray = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval())) ;
then
echo json_encode($myarray) ; // this works but only one item is pushed to my array
if i do
$myarray[] = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval //pushing all elements to array
result is nothing.
what i am missing ?
see full code below on what i have so far done.
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
/*
* Retrieve available Room types.
* TODO
* make accessing ids automatic..
*/
include_once("../../openerp_models.php"); // include file to connect with openerp
date_default_timezone_set('Europe/Moscow'); // Timezone settings
//openerp connection details
require_once("../../connection.php") ;
try {
//we access partner model and domain for customers only
$customer = $connection_model->search('res.partner', 'customer', '=', TRUE);
//
//create an array
$ids = array();
//create a for loop and loop through the ids from search
for($i = 0; $i <= count($customer); $i++ )
{
// assign array values
$ids [] = $customer[$i] ;
}
// read partner with $ids
$customer_details = $connection_model->read('res.partner', $ids);
//loop through the scalavar value
$myarray = null;
// loop through the value returned
foreach ($customer_details as $keys => $values)
{
$value = $values->scalarval();
//Push values to my array
$myarray [] = array(array('name' =>$value['display_name']->scalarval(),'id' => $value['id']->scalarval())) ;
//
}
//Then try to encode $myrray but this fails
$jsonstring = json_encode($myarray);
if ($jsonstring!==false)
{
echo $jsonstring;
} else {
echo 'Could not properly encode $myarray';
}

?>
please help. thank you.

Answer 1

The right way to create the array would be like this:
$myarray = array(
array(
'name' => 'bla',
'id' => 1
), array(
'name' => 'blas',
'id' => 2
)
);
This part of your code is perfectly fine.
$data = array() ; //create new empty array
//loop through the array
foreach($myarray as $keys => $h)
{
$data [] = $h;
}
//encode
echo json_encode($data) ; //this fails silently
If you run the code, it works perfectly fine:
[{"name":"bla","id":1},{"name":"blas","id":2}]

Answer 2

Your foreach() loop creates a new array $data with the same entries (also arrays) as the $myarray contains. So, you could directly encode $myarray like this:
<?php
$myarray = array(
array('name' =>' Agrolait', 'id' => 6 ),
array('name' => 'Agrolait, Michel Fletcher', 'id' => 31 ),
array('name' => 'Agrolait, Thomas Passot', 'id' => 30 )
);
$jsonstring = json_encode($myarray);
if ($jsonstring!==false) {
echo $jsonstring;
} else {
echo 'Could not properly encode $myarray';
}
?>
Which produces this JSON string:
[{"name":" Agrolait","id":6},{"name":"Agrolait, Michel Fletcher","id":31},{"name":"Agrolait, Thomas Passot","id":30}]
json_encodereturns the value FALSE if something went wrong, and the encoded string else. If you check the result from it you at least know when it fails.

Answer 3

Thanks for your suggestion have solved this. My string data was not properly encoded using utf-8 as suggested by http://nl3.php.net/manual/en/function.json-encode.php. Check my answer below
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
/*
* Retrieve available Room types.
* TODO
* make accessing ids automatic..
*/
include_once("../../openerp_models.php"); // include file to connect with openerp
date_default_timezone_set('Europe/Moscow'); // Timezone settings
//openerp connection details
require_once("../../connection.php") ;
try {
//we access partner model and domain for customers only
$customer = $connection_model->search('res.partner', 'customer', '=', TRUE);
//
//create an array
$ids = array();
//create a for loop and loop through the ids from search
for($i = 0; $i <= count($customer); $i++ )
{
// assign array values
$ids [] = $customer[$i] ;
}
// read partner with $ids
$customer_details = $connection_model->read('res.partner', $ids);
//loop through the scalavar value
$myarray = null;
// loop through the value returned
foreach ($customer_details as $keys => $values)
{
$value = $values->scalarval();
$myarray [] = array('name' =>utf8_encode($value['display_name']->scalarval()),'id' => utf8_encode($value['id']->scalarval())) ;
//
//array_push($better, $myarray) ;
}
//echo '<pre>';
//print_r($myarray) ;
//echo '</pre>';
echo json_encode($myarray);
exit;
}
catch(Exception $ex){
print "Error ".$ex.getMessage() ;
