I am trying to sent response in that form
{"files":[{"webViewLink":""},{"webViewLink":""}]}
But I'm getting response like that
{"files":[{"webViewLink":"""}]}{"files":[{"webViewLink":"""}]}
Here is my PHP code:
<?php
$idtemp = extractfiles($fol_id, $email);
foreach ($idtemp['items'] as $val) {
$id = $val['id'];
$val = array(
"webViewLink" => 'https://drive.google.com/file/d/'.$val['id'].'/view?usp=drivesdk"'
);
$enc = json_encode($val);
$val = '{"files":['.$enc.']}';
echo($val);
Please help me to fix code i need response in that way
{"files":[{"webViewLink":""},{"webViewLink":""}]}
You should no do $val = '{"files":['.$enc.']}';
Use json_encode to make json, don't do it manual
Create an object with desired keys outside the loop
Push anything to the desired array
Convert to json
<?php
$idtemp = extractfiles($fol_id, $email);
$json = (object) [
"files" => []
];
foreach ($idtemp['items'] as $val) {
$json->files[] = (object) [
"webViewLink" => 'https://drive.google.com/file/d/'.$val['id'].'/view?usp=drivesdk"'
];
}
$json = json_encode($json);
echo($json);
If I use some dummy values to create an example, the output is:
{
"files": [
{
"webViewLink": "https://drive.google.com/file/d/1/view?usp=drivesdk\""
},
{
"webViewLink": "https://drive.google.com/file/d/2/view?usp=drivesdk\""
},
{
"webViewLink": "https://drive.google.com/file/d/3/view?usp=drivesdk\""
}
]
}
As you can test in this online demo
I am new in php, please help with my code.
I am trying to create PHP json for IOS app. Json should looks like this
{"items": [
{
"ID":12,
"name1":"some name",
"name2":"some name2"
},
{
"ID":13,
"name1":"another name",
"name2":"another name2"
},] }
Here is my PHP code part
$keys = array(ID, name1, name2);
while ($row = mysqli_fetch_array($result))
{
extract($row);
$values = array($row['ID'], $row['name1'], $row['name2']);
$response = array_combine($keys, $values);
header('Content-Type: application/json, charset=utf-8');
echo json_encode($response, JSON_UNESCAPED_UNICODE);
}
This gives me result like this
{
"ID":12,
"name1":"some name",
"name2":"some name2"
}
{
"ID":13,
"name1":"another name",
"name2":"another name2"
}
Can anybody help me with this?
Thanks in advance.
You need to build your array, and then encode the JSON outside of the loop for a start;
$keys = array(ID, name1, name2);
$items = array();
while ($row = mysqli_fetch_array($result))
{
extract($row);
$values = array($row['ID'], $row['name1'], $row['name2']);
$item = array_combine($keys, $values);
$items[] = $item;
}
header('Content-Type: application/json, charset=utf-8');
echo json_encode(array("items"=>$items), JSON_UNESCAPED_UNICODE);
Here we build up an array of your items into $items, and then encode them all outside of the loop.
Seems you are new or really don't know something about json yet
but i'll try to help you
just simply stored it in associative array an assign items as it's index
$response = array(
'items' => array_combine($keys, $values)
);
header('Content-Type: application/json, charset=utf-8');
echo json_encode($response, JSON_UNESCAPED_UNICODE);
I am having a string below
$string = ot>4>om>6>we>34>ff>45
I would like the JSON output be like
[{"name":"website","data":["ot","om","we","ff"]}]
and
[{"name":"websitedata","data":["4","6","34","45"]}]
what I've tried
$query = mysql_query("SELECT month, wordpress, codeigniter, highcharts FROM project_requests");
$category = array();
$category['name'] = 'website';
$series1 = array();
$series1['name'] = 'websitedata';
while($r = mysql_fetch_array($query)) {
$category['data'][] = $r['month'];
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
print json_encode($result, JSON_NUMERIC_CHECK);
but the above code is applicable only if the data are present in rows from a mysql table, what i want is achieve the same result with the data from the above string. that is
$string = ot>4>om>6>we>34>ff>45
NEW UPDATE:
I would like to modify the same string
$string = ot>4>om>6>we>34>ff>45
into
json output:
[
{
"type" : "pie",
"name" : "website",
"data" : [
[
"ot",
4
],
[
"om",
6
],
[
"we",
34
]
]
}
]
I have updated the answer please check the json part, I would like the php code.
regards
You can explode() on the >s, and then loop through the elements:
$string = "ot>4>om>6>we>34>ff>45";
$array1 = [
'name'=>'website',
'data'=>[]
]
$array2 = [
'name'=>'websitedata',
'data'=>[]
]
foreach(explode('>', $string) as $index => $value){
if($index & 1) //index is odd
$array2['data'][] = $value;
else //index is even
$array1['data'][] = $value;
}
echo json_encode($array1); //prints {"name":"website","data":["ot","om","we","ff"]}
echo json_encode($array2); //prints {"name":"websitedata","data":["4","6","34","45"]}
A solution using preg_match_all():
$string = "ot>4>om>6>we>34>ff>45";
preg_match_all('/(\w+)>(\d+)/', $string, $matches);
$array1 = [
'name'=>'website',
'data'=> $matches[1]
];
$array2 = [
'name'=>'websitedata',
'data'=> $matches[2]
];
echo json_encode($array1); //prints {"name":"website","data":["ot","om","we","ff"]}
echo json_encode($array2); //prints {"name":"websitedata","data":["4","6","34","45"]}
Update:
To get the second type of array you wanted, use this:
//since json_encode() wraps property names in double quotes (which prevents the chart script from working), you'll have to build the json object manually
$string = "ot>4>om>6>we>34>ff>45";
preg_match_all('/(\w+)>(\d+)/', $string, $matches);
$data = [];
foreach($matches[1] as $index => $value){
if(isset($matches[2][$index]))
$data[] = '["' . $value . '",' . $matches[2][$index] . ']';
}
$type = 'pie';
$name = 'website';
echo $jsonString = '[{type:"' . $type . '",name:"' . $name . '",data:[' . implode(',', $data) . ']}]'; // prints [{type:"pie",name:"website",data:[["ot",4],["om",6],["we",34],["ff",45]]}]
Update #2:
This code uses explode(), and although it's probably not the most efficient way of doing it, it works.
//since json_encode() wraps property names in double quotes (which prevents the chart script from working), you'll have to build the json object manually
$string = "ot>4>om>6>we>34>ff>45";
$keys = [];
$values = [];
foreach(explode('>', $string) as $key => $value){
if(!($key & 1)) //returns true if the key is even, false if odd
$keys[] = $value;
else
$values[] = $value;
}
$data = [];
foreach($keys as $index => $value){
if(isset($values[$index]))
$data[] = '["' . $value . '",' . $values[$index] . ']';
}
$type = 'pie';
$name = 'website';
echo $jsonString = '[{type:"' . $type . '",name:"' . $name . '",data:[' . implode(',', $data) . ']}]'; // prints [{type:"pie",name:"website",data:[["ot",4],["om",6],["we",34],["ff",45]]}]
This should work, though there are probably better ways to do it.
$string = "ot>4>om>6>we>34>ff>45";
$website = ["name" => "website", "data" => []];
$websiteData = ["name" => "websitedata", "data" => []];
foreach(explode(">", $string) as $i => $s) {
if($i % 2 === 0) {
$website["data"][] = $s;
} else {
$websiteData["data"][] = $s;
}
}
echo json_encode($website);
echo json_encode($websiteData);
A regex alternative:
preg_match_all("/([a-z]+)>(\d+)/", $string, $matches);
$website = ["name" => "website", "data" => $matches[1]];
$websiteData = ["name" => "websitedata", "data" => $matches[2]];
Try this code:
$string = 'ot>4>om>6>we>34>ff>45';
$string_split = explode('>', $string);
$data = array("name" => "website");
$data2 = $data;
foreach ($string_split as $key => $value)
{
if (((int)$key % 2) === 0)
{
$data["data"][] = $value;
}
else
{
$data2["data"][] = $value;
}
}
$json1 = json_encode($data, JSON_NUMERIC_CHECK);
$json2 = json_encode($data2, JSON_NUMERIC_CHECK);
echo $json1;
echo $json2;
Output:
{"name":"website","data":["ot","om","we","ff"]}
{"name":"website","data":[4,6,34,45]}
Regards.
Try this snippet:
$strings = explode('>', 'ot>4>om>6>we>34>ff>45');
// print_r($string);
$x = 0;
$string['name'] = 'website';
$numbers['name'] = 'websitedata';
foreach ($strings as $s)
{
if ($x == 0) {
$string['data'][] = $s;
$x = 1;
} else {
$numbers['data'][] = $s;
$x = 0;
}
}
print_r(json_encode($string));
echo "<br/>";
print_r(json_encode($numbers));
As usual - it is long winded but shows all the steps to get to the required output.

In PHP, how to get a JSON value from a variable path ?
Here is a sample json and a function with 2 params: a json variable, and path split into keys.
$myjson = json_decode('{
"myKey1": {
"myKey2": {
"myKey3": {
"myKey4": "myfinalvalue"
}
}
}
}');
function getJSONValue($myjson, $pathkey) {
// split path keys by ";"
$myjson-> ?? $pathkey ??
}
echo getJSONValue($myjson, "myKey1;myKey2;myKey3;myKey4");
// Should display "myfinalvalue"
the static equivalent would be to do:
$myjson->myKey1->myKey2->myKey3->myKey4;
I tried:
$myjson->$pathkey
but unfortunately, it doesn't work...
Actually, your question has nothing to do with JSON. This is how you can get a value from a nested object:
function getValue($obj, $path) {
foreach(explode(';', $path) as $key) {
$obj = $obj->$key;
}
return $obj;
}
As for the JSON part, your example is not a valid JSON. It should be like this:
$myjson = json_decode('{
"myKey1": {
"myKey2": {
"myKey3": {
"myKey4": "myfinalvalue"
}
}
}
}');
Also, php objects are case-sensitive, if you have myKey in the object, it should be myKey (and not mykey) in the path string.
function getJSONValue($myjson, array $pathkey) {
foreach($pathkey as $val){
$myjson = $myjson->{$val};
}
return $myjson;
}
$myjson = json_decode('{"myKey1": {"myKey2": {"myKey3": {"myKey4": "myfinalvalue"}}}}');
echo getJSONValue($myjson, ["myKey1","myKey2","myKey3","myKey4"]);
live example: http://codepad.viper-7.com/1G78Fi
Something like this:
function getJSONValue() {
$args = func_get_args();
$json = array_shift($args);
$key = array_shift($args);
$value = $json->$key;
if(is_object($value)) {
array_unshift($args, $value);
return call_user_func_array('getJSONValue', $args);
}
return $value;
}
No error checking.
Seems like you are mixing PHP and JS. check this out to see how to create a Json string, then getting an onject out of it, and accessing keys:
$myjson = json_encode(array(
'myKey1' => array(
'mykey2' => array(
'mykey3' => array(
'myKey4' => "myfinalvalue"
)
)
)
));
$obj = json_decode($string);
echo $obj->myKey1->mykey2->mykey3->myKey4
// "myfinalvalue"
or pasting the json directly:
$obj = json_decode(
'{
myKey1: {
mykey2: {
mykey3: {
myKey4: "myfinalvalue"
}
}
}
}');
echo $obj->myKey1->mykey2->mykey3->myKey4
// "myfinalvalue"

I am querying a database for results and trying to convert them into JSON encodable array where the key will act as the name of the pair and the value is the value. How would I do this in the following code below?
foreach($results as $result) {
foreach( $result as $key => $value ) {
if ($key == 'D')
{
$trimmed = round($value, 4);
}
else
{
$trimmed = trim($value, "\n\r");
}
$array[$i] ="$key"."=>"."$trimmed";
}
$i = 0;
$jret = json_encode($array);
echo $jret;
}
For example:
<?php
$object[0] = array("foo" => "bar", 12 => true);
$encoded_object = json_encode($object);
?>
output:
{"1": {"foo": "bar", "12": "true"}}
dunno what you need and why you mimic PHP code instead of using it, but may be
$array[] = array($key => $trimmed);
is what you are looking for
with
$array[$i][$key] = $trimmed;
you could do
$return = json_encode($object, JSON_FORCE_OBJECT);
at the end
