I have this JSON string
{"ticker":{"high":736.45099,"low":681,"avg":708.725495,"vol":13038780.63684,"vol_cur":18382.55965,"last":726,"buy":726,"sell":724.5,"updated":1388242741,"server_time":1388242743}}
How can i get the "last" parameter after doing json_decode()?
Do like this
<?php
$json='{"ticker":{"high":736.45099,"low":681,"avg":708.725495,"vol":13038780.63684,"vol_cur":18382.55965,"last":726,"buy":726,"sell":724.5,"updated":1388242741,"server_time":1388242743}}';
$json_arr=json_decode($json,true);
echo $json_arr['ticker']['server_time'];//"prints" 1388242743 which is the last param "server time"
Use json_decode with parameters json string and TRUE.When TRUE, returned objects will be converted into associative arrays.
<?php
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json, true));
?>

need your help on this one...
I'm trying to create a code that will get a .txt file and convert all text content to json.
here's my sample code:
<?php
// make your required checks
$fp = 'SampleMessage01.txt';
// get the contents of file in array
$conents_arr = file($fp, FILE_IGNORE_NEW_LINES);
foreach($conents_arr as $key=>$value)
{
$conents_arr[$key] = rtrim($value, "\r");
}
$json_contents = json_encode($conents_arr, JSON_UNESCAPED_SLASHES);
echo $json_contents;
?>
I already got the result when i tried to echo the $json_contents
["Sample Material 1","tRAINING|ENDING","01/25/2018 9:37:00 AM","639176882315,639176882859","Y,Y","~"]
but when I tried to echo using like this method $json_contents[0]
I only got per character result.
Code
Result
hope you can help me on this one..
thank you
As PHP.net says
"Returns a string containing the JSON representation of the supplied value."
As you are using $json_contents[0] this will return the first char of the json string.
You can do this
$conents_arr[0]
Or convert your json string to PHP array using
$json_array = json_decode($json_contents, true);
echo $json_array[0];
It is happening because $json_contents is a string. It might be json string but it's string so string properties will apply here and hence when you echo $json_contents[0] it gives you first character of the string. You can either decode the encoded json string to object like below:
$json = json_decode($json_contents);
echo $json[0];
or echo it before the json_encode:
echo $conents_arr[0];
$json_contents = json_encode($conents_arr, JSON_UNESCAPED_SLASHES);
json_encode() function takes an array as input and convert it to json string.
echo $json_contents; just print out the string.
if you want to access it you have to decode the JSON string to array.
//this convert array to json string
$json_contents = json_encode($conents_arr, JSON_UNESCAPED_SLASHES);
//this convert json string to an array.
$json_contents = json_decode($json_contents, true);
//now you can access it
echo $json_contents[0];
I have an array in string given below.
$string="
"Status":true,
"ReVerifiedCount":1,
"ProfilePrefix":"INVTRK"
";
How I can get array from this string same as it exists in string.
<?php
$string='{
"Status":true,
"ReVerifiedCount":1,
"ProfilePrefix":"INVTRK"
}';
$data=json_decode($string,true);
print_r($data);
I formated your string-json the right way. Your double quotes and the missing brackets were creating the main problem as your input was not a valid json.
Output is this:
Array ( [Status] => 1 [ReVerifiedCount] => 1 [ProfilePrefix] => INVTRK )
First your String looks like a json string.
$string='{
"Status":true,
"ReVerifiedCount":1,
"ProfilePrefix":"INVTRK"
}';
This is the correct form.
To parse it use json_decode from PHP
$parsedArray = json_decode($string, true);
Here is a link to the doc : http://php.net/manual/en/function.json-decode.php
I'm having troubles with json_decode in PHP:
I have this on file:
{1: ['oi','oi'], 2: ['foo','bar']}
And this is my php code:
<?php
$string = file_get_contents("quizen.json"); // the file
$json = json_decode($string);
echo $json[1][0]
?>
But the echo returns anything, I used var_dump, and I get NULL!
What's the problem?
The issue is that your file is not valid JSON since it uses single quotes for strings and has integers as object keys:
{1: ['oi','oi'], 2: ['foo','bar']}
Also, since the JSON is an object, you should decode it to an associative array using json_decode($string, true).
According to the JSON spec:
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array.
Also, the object keys need to be strings.
If you change the single quotes to double quotes and edit your PHP's decode_json call to decode to an associative array, it should work. For example:
JSON:
{"1": ["oi","oi"], "2": ["foo","bar"]}
PHP:
<?php
$string = file_get_contents("quizen.json"); // the file
$json = json_decode($string, true); // set to true for associative array
echo $json["1"][0];
?>
Is there anything that i print the string without the array information?
(Without this: a:1:{i:0;s:4011:" ";} )?
The whole array must be in single variable and printed. Foreach doesn't help, neither print(array[0]).
You can use json_encode() which will give you less verbose string representation:
<?php
$a = array('a', 'bb' => 'ccc');
echo json_encode($a);
// outputs {"0":"a","bb":"ccc"}
You can use
echo json_encode($array);
This will print a json encoded string.
For you to decode it you can use
json_decode(json encoded string);
You can see docs of php about json encode and json decode
How can I parse json array string to array on php
'[{"a": "1", "b": "2"}, {"a": "3"}]'
seems json_decode allows parse only objects but not arrays. Should it be manually parsed to array before using json_decode?
Seems problem in string. I get a variable with json, and if I output it, looks like the json is valid
echo($jsonvar); //result [{"title":"Home","id":"/","url":"/"}]
but when I try parse string from the variable, the result is nothing even when string is trimmed
echo('[{"title":"Home","id":"/","url":"/"}]', true); //nice parsed array
echo($jsonvar, true); //nothing
echo(trim($jsonvar, " \t\n\r\0\x0B"), true); //nothing
Pass the true as a second parameter to your json_decode() to parse the json string to array.
$json='[{"a": "1", "b": "2"}, {"a": "3"}]';
$arr= json_decode($json,true);
print_r($arr);
You can get the json into array by using the true flag in json_decode()
<?php
$str = '[{"a": "1", "b": "2"}, {"a": "3"}]';
$arr=json_decode($str,true);
print_r($arr);
