I want to get value of id and name from the string given below in php. Can any body help me please.
string(35400) "{"cities":[{"id":"3279","name":"Narasaraopet"},{"id":"1852","name":"Srirangapatna"}
That's not really a valid json (missing ]} at the end), but assuming you removed something from it just to post the question, do it like this:
$json = '{"cities":[{"id":"3279","name":"Narasaraopet"},{"id":"1852","name":"Srirangapatna"}]}';
$decoded = json_decode($json, true);
foreach($decoded['cities'] as $v){
echo 'ID: ' . $v['id'] . '<br>';
echo 'Name: ' . $v['name'];
echo '<br><br>';
}
Output:
ID: 3279
Name: Narasaraopet
ID: 1852
Name: Srirangapatna
To use it as objects, you can ommit the second argument, like so:
$decoded = json_decode($json);
Then you'd access the values object-like:
foreach($decoded->cities as $v){
echo 'ID: ' . $v->id . '<br>';
// ...

Use the function json_decode(), then you'll have an array.

I am very beginner in programmer and I am learning.
I am sorry if my question is too bad.
I want to create variable in php from api content, for example:
This contents is from this URL: http://example.com/api
{"name":"John","age":"20","genre":"male","language":[{"id":"22","name":"english"},{"id":"23","name":"french"}]}
<?php
$content = file_get_contents("http://example.com/api");
$content = str_replace('"', "", $content);
$content = str_replace(":", "=", $content);
$content = str_replace(",", "&", $content);
parse_str($content);
echo $name; //John
echo $age; //20
echo $genre; //male
echo $language //[{id <======== here is my problem
?>
My problem is when I am getting an array like "language", how to fix it?
Thanks for help.
U can use the http://www.php.net/json_decode in two ways :
This is object oriented :
$str = '{"name":"John","age":"20","genre":"male","language":[{"id":"22","name":"english"},{"id":"23","name":"french"}]}';
$json = json_decode($str);
echo 'name: ' . $json->{'name'} .'<br>';
echo 'age: ' . $json->{'age'} .'<br>';
echo 'genre: ' . $json->{'genre'} . '<br>';
foreach($json->{'language'} as $data){
echo 'id: ' . $data->{'id'} . '<br>';
echo 'name: ' . $data->{'name'} . '<br>';
}
As an associative array :
$json = json_decode($str, true);
echo 'name: ' . $json['name'] .'<br>';
echo 'age: ' . $json['age'] .'<br>';
echo 'genre: ' . $json['genre'] . '<br>';
foreach($json['language'] as $data){
echo 'id: ' . $data['id'] . '<br>';
echo 'name: ' . $data['name'] . '<br>';
}
json_decode() will help you to convert the string data to something more accessible:
<?php
// Instead of your fetched data we use static example data in this script
//$content = file_get_contents("http://example.com/api");
$content = '{"name":"John","age":"20","genre":"male","language":[{"id":"22","name":"english"},{"id":"23","name":"french"}]}';
// Convert json data to object
$data = json_decode($content);
// access object properties by using "->" operator
echo $data->name;
echo $data->age;
echo $data->genre;
// language is an array of objects, so let's look at each language object...
foreach($data->language as $lang) {
// ... and extract data using "->" again
echo $lang->id;
echo $lang->name;
}
A live example of this code can be found at http://sandbox.onlinephpfunctions.com/code/6df679c3faa8fff43308a34fb80b2eeb0ccfe47c
As pointed out by #fusionK, the response from the api request is a json string so convert to an object ( or array if preferred ) using json_decode ( json_decode( $data,true ) for an array )
Once it is decoded it is straightforward to access the properties of the object.
<?php
/* capture and decode response from api - creates an object */
$content = json_decode( file_get_contents("http://example.com/api") );
/* using object notation to access properties */
echo $content->name.' '.$content->age.' '.$content->genre;
/* for the language which is an array of objects */
$lang=$content->language;
foreach( $lang as $language ){
$obj=(object)$language;
echo $obj->id.' '.$obj->name;
}
?>
I already view a lot of questions in stackoverflow about my problem, but I didn't find any solution. I don't know where is the problem in my code? I got illegal string offset message at this row:
echo $value["country"] . ", " . $value["competition"] . "<br>";
My full code:
<?php
// file_get_contents call instead
$str = file_get_contents('general.json');
$json = json_decode($str,true);
foreach($json as $key => $value){
echo $value["country"] . ", " . $value["competition"] . "<br>";
}
?>
my json source sample:
["{\"country\":\"America\",\"competition\":\"Copa America\",\"club\":\"BOCA JUNIORS\"}","{\"country\":\"Germany\",\"competition\":\"Bundesliga\",\"club\":\"HANNOVER\"}","{\"country\":\"Asia\",\"competition\":\"JLeague\",\"club\":\"NAGOYA\"}"]
If I view format of the data with var_dump($json) then I see it is an Array. With var_dump($value) then I see there is a string. Please help for me where is the problem in my code, why could not echo value country and value competition?
The problem is that you have json that has been encoded twice, both the array and the elements in the array.
You should avoid doing that, but if you cannot change the source, you need to decode the values as well:
<?php
// file_get_contents call instead
$str = file_get_contents('general.json');
$json = json_decode($str,true);
foreach($json as $key => $value){
// decode the $value string
$value = json_decode($value, true);
echo $value["country"] . ", " . $value["competition"] . "<br>";
}
?>
An example.
I have a JSON file called from an URL. I've checked and I'm getting the the data from the URL.
I've tried a lot, but I can't get the loop foreach to work - what is wrong?
<?php
$url = 'http://banen.klintmx.dk/json/ba-simple-proxy.php?url=api.autoit.dk/car/GetCarsExtended/59efc61e-ceb2-463b-af39-80348d771999';
$json= file_get_contents($url);
$data = json_decode($json);
$rows = $data->{'contents'};
foreach($rows as $row) {
echo '<p>';
$FabrikatNavn = $row->{'contents'}->{'FabrikatNavn'};
$ModelNavn = $row->{'contents'}->{'ModelNavn'};
$PrisDetailDkk = $row->{'contents'}->{'PrisDetailDkk'};
echo $FabrikatNavn . $ModelNavn . ' Pris ' . $PrisDetailDkk;
echo '</p>';
}
?>
The actual problem is you trying to access content object again. Just change your foreach snippet with,
foreach ($rows as $row) {
echo '<p>';
$FabrikatNavn = $row->FabrikatNavn;
$ModelNavn = $row->ModelNavn;
$PrisDetailDkk = $row->PrisDetailDkk;
echo $FabrikatNavn . $ModelNavn . ' Pris ' . $PrisDetailDkk;
echo '</p>';
}
DEMO.
Use json_decode($data, true) so that it parses the JSON content into a PHP array. So it will be something like
$rows = $data['contents'];
foreach($rows as $row) {
echo '<p>';
$FabrikatNavn = $row['contents']['FabrikatNavn'];
$ModelNavn = $row['contents']['ModelNavn'];
$PrisDetailDkk = $row['contents']['PrisDetailDkk'];
echo $FabrikatNavn . $ModelNavn . ' Pris ' . $PrisDetailDkk;
echo '</p>';
}
Take a look at using json_decode($json, true) as this will convert the data to an associative array which seems to be the way you are approaching the solution.
Check the output by printing with var_dump() or print_r()
Try like this
$data = json_decode($json,true); //decode json result as array and thenloop it
print '<pre>';
print_r($data);
foreach($data as $row){
//do something here
}
simple script gets a json file, strips out extraneous headers, and tried to access a single key/value with no luck. anyone?
CODE
$postURL = "http://case42.com/ogle/GetTarget.php?targetid=32feaf056b8c46e4a6f5500b6289cf59";
$json = file_get_contents($postURL);
echo "original response = <P>" . $json ."<HR>";
$strip = "target_record";
$mypos = strpos($json, $strip);
$json = substr($json,$mypos+15);
echo "My Trimmed json is: <P>" . $json."<HR>";
$obj = json_decode($json, true);
echo "<P>The print _ r of the trimmed json prints:<P> " . print_r ($json);
echo "<HR>";
echo "using \"\$obj->{'target_id'}\" to get name give me this: ".$obj->{'name'}."<HR>";
The results are:
original response =
GET
d41d8cd98f00b204e9800998ecf8427e
Mon, 16 Dec 2013 10:36:23 GMT
/targets/32feaf056b8c46e4a6f5500b6289cf59{"target_record":{"target_id":"32feaf056b8c46e4a6f5500b6289cf59","name":"Francesca Grace","width":300.0,"active_flag":true,"tracking_rating":5,"reco_rating":""},"status":"success","result_code":"Success","transaction_id":"23029749e4984e2d92dbfb5ff44f8834"}
My Trimmed json is:
{"target_record":{"target_id":"32feaf056b8c46e4a6f5500b6289cf59","name":"Francesca Grace","width":300.0,"active_flag":true,"tracking_rating":5,"reco_rating":""},"status":"success","result_code":"Success","transaction_id":"b427cb1f89544b4c85332ca0ad174848"}
The print_r of the trimmed json prints:
1
using "$obj->{'target_id'}" to get name give me this:
try this:
$postURL = "http://case42.com/ogle/GetTarget.php?targetid=32feaf056b8c46e4a6f5500b6289cf59";
$json = file_get_contents($postURL);
echo "original response = <P>" . $json ."<HR>";
$strip = "target_record";
$mypos = strpos($json, $strip);
$json = substr($json,$mypos-2);
echo "My Trimmed json is: <P>" . $json."<HR>";
$obj = json_decode($json, true);
echo "<P>The print _ r of the trimmed json prints:<P> " . print_r ($json);
echo "<HR>";
echo "using \"\$obj->{'target_id'}\" to get name give me this: ".$obj['tagret_record']['name']."<HR>";
Simple solution: using "true" in the json_decode converts the object to an associative array. Items inside are then accessed at $Array[$key][key].
