PHP JSON Encoding within foreach loop - php

Question

I'm trying to generate the following JSON data:
[
{
"ID": "A1000",
"name": "John Simpson",
"serialID": "S41234",
"tagID": "ABC6456"
},
{
"ID": "B2000",
"name": "Sally Smith",
"serialID": "B5134536",
"tagID": "KJJ451345"
},
{
"ID": "A9854",
"name": "Henry Jones",
"serialID": "KY4239582309",
"tagID": "HYG452435"
}
]
from within a PHP foreach loop which looks like this:
foreach($records as $record) {
$ID = $record->getField('propertyID');
$name = $record->getField('assignedName');
$serialID = $record->getField('serial');
$tagID = $record->getField('tag');
}
I've tried using:
$arr = array('ID' => $ID, 'name' => $name, 'serialID' => $serialID, 'tagID' => $tagID);
which works for each record within the loop, but can't work out the syntax to join them together into a single JSON data string?

Answer 1

Problem:- Your are over-writing your $arr variable each-time inside foreach() loop.That cause the issue.
Solution:- Instead of over-writing, assign values to array like below:-
$arr = []; //create empty array
foreach($records as $record) {
$arr[] = array(
'ID' => $record->getField('propertyID');
'name' => $record->getField('assignedName');
'serialID' => $record->getField('serial');
'tagID' => $record->getField('tag')
);//assign each sub-array to the newly created array
}
echo json_encode($arr);

Answer 2

Add records to some kind of aggregation array and then json_encode it:
$items = [];
foreach($records as $record) {
$items[] = [
'ID' => $record->getField('propertyID'),
'name' = $record->getField('assignedName'),
'serialID' => $record->getField('serial'),
'tagID' => $record->getField('tag'),
];
}
echo json_encode($items);

Answer 3

Try this:
$data= array();
foreach($records as $record) {
$data[] = array(
'ID' => $record->getField('propertyID');
'name' => $record->getField('assignedName');
'serialID' => $record->getField('serial');
'tagID' => $record->getField('tag')
);
}
echo json_encode($data);
Explanation: Make an array, put all the values on one of their numerical index with in the loop, json_enccode() it.

Answer 4

<?php
$ArrayName = array();
foreach($records as $record) {
$ID = $record->getField('propertyID');
$name = $record->getField('assignedName');
$serialID = $record->getField('serial');
$tagID = $record->getField('tag');
$ArrayName[] = array('ID' => $ID, 'name' => $name, 'serialID' => $serialID, 'tagID' => $tagID); //assign each sub-array to the newly created array
}
echo json_encode($ArrayName);

Answer 5

You could use something like array_map() for this:
$result = array_map(function ($record) {
return [
'ID' => $record->getField('propertyID'),
'name' => $record->getField('assignedName'),
'serialID' => $record->getField('serial'),
'tagID' => $record->getField('tag'),
];
}, $records);
echo json_encode($result);

Answer 6

this code will help you:
<?php
$resultArray = array();
foreach($records as $record)
{
$newResultArrayItem = array();
$newResultArrayItem['ID'] = $record->getField('propertyID');
$newResultArrayItem['name'] = $record->getField('assignedName');
$newResultArrayItem['serialID'] = $record->getField('serial');
$newResultArrayItem['tagID'] = $record->getField('tag');
$resultArray[] = $newResultArrayItem;
}
$encodedArray = json_encode($ArrayName);
echo $encodedArray;
?>
