Retrieve name-value pair into PHP array - php

I need some help. I have a variable containing this string;
[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"},{"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]
I need to retrieve the id and value for each pair and make it any array in PHP.

You can use json_decode and pass the second param as true so it returns an array like this
$json = '[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"},{"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]';
$decoded = json_decode($json,true);
print_r($decoded);
Working Example
Output would be
Array
(
[0] => Array
(
[id] => 17
[value] => 123456789
)
[1] => Array
(
[id] => 18
[value] => 2012-06-13
)
[2] => Array
(
[id] => 19
[value] => Kampala
)
[3] => Array
(
[id] => 20
[value] => 1
)
.......
)
Which you can loop through using foreach like.
foreach($decoded as $de){
// access id with $de['id']
// access value with $de['value']
}

You have got an json string. You can convert it to an array by using function json_decode
Check this code .
$str = '[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"}, {"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]';
$array = json_decode($str);
foreach($array as $temp){
echo "ID : ".$temp->id."\t Value: ".$temp->value;
echo "<br />";
}

How can I put JSON to MySQL with PHP loop?

I have JSON like this (from nested sorting)
[
{"id":13},{"id":14},
{"id":15,
"children":[
{"id":16},{"id":17},{"id":18}
]
},
{"id":19},{"id":20},
{"id":21,
"children":[
{"id":22}
]
}
]
how I PHP loop to put this JSON in MySQL
Thank you.
As with any valid JSON format string, you can use PHP's built-in json_decode to convert it into a parsable object and then loop through those parameters. In this case, from the JSON string you've given (which seems to be an array)
$array = json_decode($string);
foreach ($array as $val) {
//The object $val will be:
"id":13
}
If it's nested, you would do another foreach loop and detect for the property that needs to be looped. For example you could do this in a variety of ways (check for the "children" property, loop through the $val properties and check if it is an array, if it is then loop through that). Inside this foreach loop iteration, you can insert it, or do execute whatever statement you need to get it inside MySQL
Your question is pretty vague on the format and way you want it inserted. I'd suggest showing some code you've tried so other people can help you and know what direction you're going in. (that's probably the reason for the downvote, not mine by the way)
Looping through all the properties of object php
just put your valid json inside json_decode and assign it to a php array as below
//$php_arr = json_decode('YOUR_JSON');
$php_arr = json_decode('[{"id":13},{"id":14},{"id":15,"children":[{"id":16},{"id":17},{"id":18}]},{"id":19},{"id":20},{"id":21,"children":[{"id":22}]}]');
/*comment the following 3 lines when done*/
echo "<pre>";
print_r($php_arr);
echo "</pre>";
/*comment the above 3 lines when done*/
output
Array
(
[0] => stdClass Object
(
[id] => 13
)
[1] => stdClass Object
(
[id] => 14
)
[2] => stdClass Object
(
[id] => 15
[children] => Array
(
[0] => stdClass Object
(
[id] => 16
)
[1] => stdClass Object
(
[id] => 17
)
[2] => stdClass Object
(
[id] => 18
)
)
)
[3] => stdClass Object
(
[id] => 19
)
[4] => stdClass Object
(
[id] => 20
)
[5] => stdClass Object
(
[id] => 21
[children] => Array
(
[0] => stdClass Object
(
[id] => 22
)
)
)
)
Now as you have PHP array do what ever you want like
foreach($php_arr as $arr){
if(!isset($arr['children'])){
$q = "insert into tbl(id) values('".$arr['id']."')";
}else{
//your logic
}
}
You need to use json_decode function to decode JSON data. Then use foreach loop to manipulate data.
Try example
$str = '
[{"id":13},{"id":14},{"id":15,"children":[{"id":16},{"id":17},{"id":18}]},{"id":19},{"id":20},{"id":21,"children":[{"id":22}]}]
';
$json = json_decode($str);
//var_dump($json);
foreach ($json as $item)
{
//The object $val will be:
echo $item->id."<br />";
//You INSERT query is here
//echo "INSERT INTO table (field) VALUE ($item->id)";
$query = mysqli_query($conn, "INSERT INTO table (field) VALUE ($val->id)");
}

Extract specific values from JSON Array php

I have a JSON Array
[0] => Array
(
[stage_id] => 80
[yieldVal] => Array
(
[0] => Array
(
[datajson] => [{"name":"doi","value":"215"},{"name":"dateofpollinationstops","value":"Date of Pollination Stops~23-3-2015"}]
)
[1] => Array
(
[datajson] => [{"name":"doi","value":"698"},{"name":"dateofpollinationstops","value":"Date of Pollination Stops~23-3-2015"}]
)
)
)
I need to extract the values from this Array
[0] => Array
(
[stage_id] => 80
[yieldVal] => Array
(
[doi_value] => 215
[doi_value] => 698
)
)
I have tried decoding the JSON. But unable to continue further.
$phpArray = json_decode($res['datajson'], true);
How to extract the values and assign the key.
EDIT : My final output should be
[0] => Array
(
[stage_id] => 80
[yieldVal] => 913 //215+698 -> Extracting values from [datajson]
)
One thing that may of tripped you up is that your datajson string is:
`[{"name":"doi","value":"215"},{"name":"dateofpollinationstops","value":"Date of Pollination Stops~23-3-2015"}]`
The square brackets mean that json_decode will create an array from the objects.
Anyway, try this...should give you the exact output you asked for:
$yieldVal = 0;
foreach ($res['yieldVal'] as $key => $arr) {
$decode = json_decode($arr['datajson']);
$yieldVal = $yieldVal + $decode[0]->value;
}
$newArray = array (
'stage_id' => $res['stage_id'],
'yieldVal' => $yieldVal
);
//var_dump($newArray);
echo "<pre>".print_r($newArray, true)."</pre>";
You should be able to get the value with:
$doi_value = $phpArray[0]['value'];
You can then sum them, push them onto a resulting array, or whatever.

Retrieving values from multi level array

Hi would love some help on how to perform this. Cause so far what I'm doing now is failing.
this is the sample output of json turned to array.
Array
(
[0] => Array
(
[0] => Array
(
[value] => lit-PR-00-Preparing-Precise-Polymer-Solutions.html
)
)
[1] => Array
(
[0] => Array
(
[value] => 90Plus
)
)
[2] => Array
(
[0] => Array
(
[value] => Particle Size Analyzer
)
)
)
So far this is what I got so far and It's still not outputting the value I need. Would appreciate some help on what I'm doing wrong thanks.
$decode = json_decode($row['elements'], true);
echo '<pre>';
//print_r($decode);
print_r(array_values($decode));
echo '</pre>';
echo ($value['0'][1][value]);
$decode = json_decode($row['elements'], true);
// iterate through array
foreach($decode as $array_row) {
echo $array_row[0]['value'];
}
// display specific row #2
echo $decode[2][0]['value'];
PHP Arrays

Illegal string offset in array

I use a library for Synchronize a local WebSQL DB to a server specifically https://github.com/orbitaloop/WebSqlSync.
I use PHP: 5.4.7,
When I try to get the array values ​​as follows, I get the message
Illegal string offset 'clientes'
the $obj var is:
Array
(
[info] =>
[data] => Array
(
[clientes] => Array
(
)
[conceptos_gastos] => Array
(
)
[formaspago] => Array
(
[0] => Array
(
[idFormaPago] => 10
[FormaPago] => qwerqwe
[Dias] => 1
[Cuotas] => 1
[last_sync_date] =>
)
)
[listaprecios] => Array
(
)
[producto] => Array
(
)
[repartidores] => Array
(
)
[tipodocumento] => Array
(
)
[vehiculos] => Array
(
)
[zonas] => Array
(
)
)
)
this is the loop
foreach ($obj as $row => $value) {
echo $row["clientes"]["fomaspago"]["FormaPago"];
}
eternally grateful for any help
it seems to be
$row["data"]["clientes"] // which is an empty array
or
$row["data"]["formaspago"][0]["FormaPago"] // which should output "qwerqwe"
The element $row["clientes"]["fomaspago"]["FormaPago"]; does indeed not exist - look at the output: the 1st row "info" does not have that index, the 2nd row "data" has "clientes" and also "fomasgapo", but does not have a "clientes" "fomasgapo".
You need to either structure your data differently or loop through it differently...
thanks to all but the only way that worked was as follows:
foreach($obj->data->formaspago as $formaspago) {
print " id ".$formaspago->idFormaPago;
print " Formapago ".$formaspago->FormaPago;
print " dias ".$formaspago->Dias;
print " cuotas ".$formaspago->Cuotas;
print " lastsyncdate ".$formaspago->last_sync_date;
}
foreach($obj->data->clientes as $formaspago) {
print " id ".$formaspago->IdCliente;
print " Cliente ".$formaspago->Cliente;
}

Getting an array from object using SimpleXMLElement

I'm having some problems getting the array in these objects. When I print_r(), the following code is printed. $message_object is the name of the object.
SimpleXMLElement Object
(
[header] => SimpleXMLElement Object
(
[responsetime] => 2012-12-22T14:10:09+00:00
)
[data] => SimpleXMLElement Object
(
[id] => Array
(
[0] => 65233
[1] => 65234
)
[account] => Array
(
[0] => 20992
[1] => 20992
)
[shortcode] => Array
(
[0] => 3255
[1] => 3255
)
[received] => Array
(
[0] => 2012-12-22T11:04:30+00:00
[1] => 2012-12-22T11:31:08+00:00
)
[from] => Array
(
[0] => 6121843347
[1] => 6121820166
)
[cnt] => Array
(
[0] => 24
[1] => 25
)
[message] => Array
(
[0] => Go tramping wellington 11-30
[1] => Go drinking Matakana 2pm
)
)
)
I'm trying to get the id arrays out of the objects with a foreach:
foreach($message_object->data->id AS $id) {
print_r($id);
}
The following reply is sent:
SimpleXMLElement Object ( [0] => 65233 ) SimpleXMLElement Object ( [0] => 65234 )
How do I get the value of [0] or am I going about this wrong? and is there a way to loop though the results and get the object keys?
I have tried to echo $id[0] but it returns no result.
When you use print_r on a SimpleXMLElement there comes magic in between. So what you see is not actually what is there. It's informative, but just not the same as with normal objects or arrays.
To answer your question how to iterate:
foreach ($message_object->data->id as $id)
{
echo $id, "\n";
}
to answer how to convert those into an array:
$ids = iterator_to_array($message_object->data->id, 0);
As this would still give you the SimpleXMLElements but you might want to have the values you can either cast each of these elements to string on use, e.g.:
echo (string) $ids[1]; # output second id 65234
or convert the whole array into strings:
$ids = array_map('strval', iterator_to_array($message_object->data->id, 0));
or alternatively into integers:
$ids = array_map('intval', iterator_to_array($message_object->data->id, 0));
You can cast the SimpleXMLElement object like so:
foreach ($message_object->data->id AS $id) {
echo (string)$id, PHP_EOL;
echo (int)$id, PHP_EOL; // should work too
// hakre told me that this will work too ;-)
echo $id, PHP_EOL;
}
Or cast the whole thing:
$ids = array_map('intval', $message_object->data->id);
print_r($ids);
Update
Okay, the array_map code just above doesn't really work because it's not strictly an array, you should apply iterator_to_array($message_object->data_id, false) first:
$ids = array_map('intval', iterator_to_array$message_object->data->id, false));
See also: #hakre's answer.
You just need to update your foreach like this:
foreach($message_object->data->id as $key => $value) {
print_r($value);
}
