Parse JSON with PHP: Syntax complication - php

Question

I'm getting the following errors:
Notice: Undefined index: value in C:\fileSystemLocation/phpFile.php on line 43
Notice: Undefined index: value in C:\fileSystemLocation/phpFile.php on line 44
when I'm trying to parse the following json data:
"data":[
"phone":[
{"value":"",
"primary":true
}],
"email":[
{"value":"",
"primary":true
}]
]
With the following statements
$response = json_decode($json_response, 1);
// Gets the count of records returned from the api. Used in the for loop to go through response 1 array element at a time.
$count = Count($response['data']);
//create array of the json data we want to export to csv
for ($x=0; $x<$count; $x++)
{
$jsonDataInArray[] = array
(
"phone" => $response['data'][$x]['phone']['value'],
"email" => $response['data'][$x]['email']['value'],
)
}
What is wrong with the syntax of the above 2 statements? I'm wondering if there is any error with my syntax above specifically with "phone" => $response['data'][$x]['phone']['value'],
"email" => $response['data'][$x]['email']['value'],

Answer 1

Looks like your JSON data is missing {} (malformed) and, also, you're using a phone key (alphabetical) on a numerical key array ([]). To use alphabetical keys you have to have a dictionary ({}, key-value arrays). Looks like your JSON should be like this:
{
"data" :
[
{
"phone" :
{
"value" : "",
"primary" : true
},
"email" :
{
"value" : "",
"primary" : true
}
}
]
}
Also remember that the function to count items in an array is count(), not Count() (capitalization matters).
I would do this then:
$jsonDataInArray = array();
$response = json_decode( $json_response, TRUE );
$data = $response['data'];
$count = count( $data );
foreach ( $data AS $index => $object )
{
$values = array(
"phone" => $data[$index]['phone']['value'],
"email" => $data[$index]['email']['value']
);
array_push( $jsonDataInArray, $values );
}

Here's the syntax that worked for me:
"phone" => $response['data'][$x]['phone'][0]['value'],
"email" => $response['data'][$x]['email'][0]['value']
The ending objects in the json data looked like (WARNING: not the whole string of json data, just the end):
"phone":[{"value":"","primary":true}],"email":[{"value":"","primary":true}]
and since there are arrays, I have to include the [0]
The following code:
"phone" => $response['data'][$x]['phone']['value'],
"email" => $response['data'][$x]['email']['value']
Would work with these ending json data objects (WARNING: not the whole string of json data, just the end):
"phone":{"value":"","primary":true},"email":{"value":"","primary":true}

Answer 3

Your syntax inside your loop is wrong. Change:
"email" => $response['data'][$x]['email']['value'],
To:
$email = $response['data'][$x]['email']['value'];
