I have an array $arr_name which prints out
{"name" => "tom", "age" => 10}, {"name" => "jack", "age" => 11}
how do i get it to print the desired output using php ?
Desired Output in JSON is as follows
{
"Students" : [ {"name" => "tom", "age" => 10}, {"name" => "jack", "age" => 11}
]
}
Sorry but i find this very very confusing and have spent the last 2 hrs trying to get "Students" key asssigned to have a value with the contents of $arr_name
PHP already has a built in function to convert an array into JSON:
json_encode
Here simple example given below like:
Put your array place of $put_your_array in loop:
$output=array();
foreach ($put_your_array as $key => $value) {
$output['Students'][]=array(
'name'=>$value['name'],
'age'=>$value['age']
);
}
echo json_encode($output);
And get output would you seem like json format...
the easiest way to do that, loop through the array then assign it to new array
Ex:
$new_array=array();
foreach(your array as $key => $val)
{
$new_array['Students'][] = $val;
}
return json_encode($new_array);

I am trying to encode an associative array in php
$data = array(
"firstName" => $_POST["firstName"],
"lastName" => $_POST["lastName"],
"email" => $_POST["email"],
"telephone" => $_POST["telephone"]
);
however the output is in string format and not in array format.
string(98) "{"firstName":"rob","lastName":"shelford","email":"some#domain.co.uk","telephone":"01245454545"}"
The output needs to have the square brackets so the receiving server can read the data correctly.
Is there another syntax for the $data array I need to use?
EDIT 1
The offical PHP documentation https://www.php.net/manual/en/function.json-encode.php
states that
echo "Normal: ", json_encode($a), "\n";
can be used to output
Normal: ["<foo>","'bar'","\"baz\"","&blong&","\u00e9"]
however when I try to use the "\n" flag, I receive an error
EDIT 2
The entire data I wish to convert
$data = array(
"applicants" => array(
"firstName" => $_POST["firstName"],
"lastName" => $_POST["lastName"],
"email" => $_POST["email"],
"telephone" => $_POST["telephone"]
),
"buyerType" => $_POST["buyerType"],
"organisationId" => "xxxxxxxxxx",
"introducerId" => "0",
"introducerBranchId" => "0",
"introducerNegotiatorId" => "0",
);
EDIT 3
I have made it work by passing this into json_encode() :
$data = array(
"applicants"=> [
array(
"email"=> $_POST["email"],
"firstName"=> $_POST["firstName"],
"lastName"=> $_POST["lastName"],
"telephone"=> $_POST["telephone"]
)
],
"buyerType" => $_POST["buyerType"],
"organisationId" => "xxxxxxxxxx",
);
I have also removed the unnecessary lines in the above example
EDIT 4
The actual output I was expecting, and actually got, after implementing EDIT3
string(138) "{"applicants":[{"email":"some#domain.co.uk","firstName":"rob","lastName":"test","telephone":"01200000000"}],"buyerType":"Purchase"}"
If you want nested array to be encoded with square brackets surrounded, just put it in an array in php.
$data['applicants'] = [$data['applicants']];
echo json_encode($data);
FYI indexed array [1,2] will be encoded to json list [1,2], and associative array ['x'=>1,'y'=>2] will be encoded to json object {"x":1,"y":1}.

I have an array with following elements:
$arr = array(
'nick' => "blabla",
'pass => "blabla2"'
);
I would like to convert it somehow to strings, the first string would be the value of nick - "blabla", the second string would be the value of pass - "blabla2"
Thank you.
If you want to convert elements of the array to separate string variables you can use extract function to import elements from an array to variables. For example:
$arr = array(
'nick' => "blabla",
'pass' => "blabla2"
);
extract($arr);
echo $nick, ' ', $pass;
$arr = [
'nick' => "blabla",
'pass' => "blabla2"
];
$string_one=$arr['nick'];
$string_two=$arr['pass'];

In My Web Application I am Using Json. I Need to create following Format of Json File in PHP.
{
"title": "A cool blog post",
"clicks": 4000,
"children": null,
"published": true,
"comments": [
{
"author": "Mister X",
"message": "A really cool posting"
},
{
"author": "Misrer Y",
"message": "It's me again!"
}
]
}
Here is the solution:
Open Google
Type PHP JSON
hit Enter
Click the 1st result
Replace the values from PHP examples with json_encode with your own values
json_encode will encode a PHP array as a JSON array.
As the exmaple on that link shows:
<?php
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
echo json_encode($arr);
// {"a":1,"b":2,"c":3,"d":4,"e":5}

Hi I need to generate json code with php like this http://api.androidhive.info/contacts/
You are looking for json_encode(). Passing an associative array to it will return a JSON representation.
http://us1.php.net/json_encode
You can use an multi-dimensional array with the json_encode function to achieve this structure.
$var = array(
"contacts" => array (
array(
"id" => 1,
"name" => "foo"
),
array(
"id" => 2,
"name" => "bar"
)
)
);
echo json_encode($var);

I have an array in PHP $array which has elements like
$array['id'].. $array['name'] $array['class']
I have another array called $array1 which has element only $array1['uid'].
I want to match these two array on the basis of $array['id'] and $array['uid']
such that I want to get elements $array['id'] not equal to $array['uid']`
Is there any builtin function in PHP, I can do that in for each loop with my custome function , but is there any function?
Input is if $array has id=2,4,5,6 and $array has uid=2,4 then I should get $array id=5,6
Data in $array looks like this
{
"name": "abc",
"id": "37402526"
},
{
"name": "def",
"id": "506768590"
},
{
"name": "hij",
"id": "526405977"
}
And $array 1 like this
{
"id": "37402526"
},
{
"id": "506768590"
},
{
"
"id": "526405977"
}
If you can rewrite your code, to have the id's in array keys, than you could use array_diff_key():
$array = array(
'12' => array('name' => 'abc'),
'34' => array('name' => 'def')
);
$array2 = array('12' => true);
$result = array_diff_key($array, $array2);
Otherwise you can use array_udiff():
function my_id_cmp($a, $b) {
return strcmp($a['id'], $b['id']);
}
$result = array_udiff($array, $array1, 'my_id_cmp');
If your input is just in the format you used as example, then it is simple :
$array['id'] = implode(',', array_diff(explode(',', $array['id']), explode(',', $array1['uid'])));
