When I use the code below:
print_r($jsoni);
$badge_url = "http://api.steampowered.com/ISteamUserStats/GetGlobalAchievementPercentagesForApp/v0002/?gameid=841370%3Fkey&steamids=76561198108211948&fbclid=IwAR0B4wUlosbqFElHBJw-AkLwb3mGsv42xKdtrEAarDmD97Ur3AprrkW4tCk";
$jsoni = json_decode(file_get_contents($badge_url), true);
I get the following as a result:
Array
(
[achievementpercentages] => Array
(
[achievements] => Array
(
[0] => Array
(
[name] => GAME_GREEN_LIGHT
[percent] => 70.9000015259
)
[1] => Array
(
[name] => CAREER_EARN_BADGE
[percent] => 62.2999992371
)
How can I get it so that it only shows the name and the percentage?
print_r($jsoni['achievementpercentages']['achievements'])
You could loop through the decoded data to create an associative array with the achievement names as keys and the percentages as values:
$achievements = [];
foreach($jsoni['achievementpercentages']['achievements'] as $achievement)
$achievements[$achievement['name']] = $achievement['percent'];
Which outputs:
Array
(
[GAME_GREEN_LIGHT] => 70.9000015259,
[CAREER_EARN_BADGE] => 62.2999992371
)
So im now using the following code.
<?php
$achievements = [];
foreach($jsoni['achievementpercentages']['achievements'] as $achievement)
$achievements[$achievement['name']] = $achievement['percent'];
print_r($achievements);
?>
wich results in
Array ( [GAME_GREEN_LIGHT] => 70.9000015259 [CAREER_EARN_BADGE] => 62.2999992371
how do i get it to show a list from top to bottom instead of in a cluster of text?
Thanks for the help!
Hi would love some help on how to perform this. Cause so far what I'm doing now is failing.
this is the sample output of json turned to array.
Array
(
[0] => Array
(
[0] => Array
(
[value] => lit-PR-00-Preparing-Precise-Polymer-Solutions.html
)
)
[1] => Array
(
[0] => Array
(
[value] => 90Plus
)
)
[2] => Array
(
[0] => Array
(
[value] => Particle Size Analyzer
)
)
)
So far this is what I got so far and It's still not outputting the value I need. Would appreciate some help on what I'm doing wrong thanks.
$decode = json_decode($row['elements'], true);
echo '<pre>';
//print_r($decode);
print_r(array_values($decode));
echo '</pre>';
echo ($value['0'][1][value]);
$decode = json_decode($row['elements'], true);
// iterate through array
foreach($decode as $array_row) {
echo $array_row[0]['value'];
}
// display specific row #2
echo $decode[2][0]['value'];
PHP Arrays
I have tried to use PHP decode to parse my JSON string below into an array so I can extract the current and day for both channels from the file.
my json file owl_output.json looks like..
{"channels":{"0":[{"current":1288,"units":"w"},{"day":31278.57,"units":"wh"}],"1": [{"current":660,"units":"w"},{"day":9191.11,"units":"wh"}]}}
I'am only ever getting one result displayed, the php code I have managed to get working is below
<?php
$string = file_get_contents('owl_output.json');
$data = json_decode($string,true);
print_r($json);
foreach ($data['channels']['0'] as $data)
{
echo $data ['current'];
}
?>
This only display the current for channel 0. If I try to add additional fields it doesn't display
echo $data ['current']['day']; ( doesn't work )
Can someone advise how I can display current and day for both channels 0 & 1 ?
My aim is to display this in a html page at the end and to keep polling the json file?
The array it displays is below
Array
(
[channels] => Array
(
[0] => Array
(
[0] => Array
(
[current] => 1288
[units] => w
)
[1] => Array
(
[day] => 31278.57
[units] => wh
)
)
[1] => Array
(
[0] => Array
(
[current] => 660
[units] => w
)
[1] => Array
(
[day] => 9191.11
[units] => wh
)
)
)
)
Can anyone offer any assistance with this ?
Thanks
The variable $data is conflicting:
Used to store the data, and used in the foreach loop. Rename the $data variable in the foreach for example:
<?php
$string = file_get_contents('owl_output.json');
$data = json_decode($string,true);
print_r($json);
foreach ($data['channels'] as $channel)
{
echo $channel[0]['current'];
echo $channel[1]['day'];
}
?>
I did edit since there was an other error because there is not 'current' in every record.
Conflict on $data reference in loop and bad array indexes :
foreach ($data['channels'] as $channel)
{
echo $channel[0]['current'];
echo $channel[1]['day'];
}
foreach ($data['channels'] as $chanel)
{
echo $chanel[0]['current'];
echo $chanel[1]['day'];
}
I need some help. I have a variable containing this string;
[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"},{"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]
I need to retrieve the id and value for each pair and make it any array in PHP.
You can use json_decode and pass the second param as true so it returns an array like this
$json = '[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"},{"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]';
$decoded = json_decode($json,true);
print_r($decoded);
Working Example
Output would be
Array
(
[0] => Array
(
[id] => 17
[value] => 123456789
)
[1] => Array
(
[id] => 18
[value] => 2012-06-13
)
[2] => Array
(
[id] => 19
[value] => Kampala
)
[3] => Array
(
[id] => 20
[value] => 1
)
.......
)
Which you can loop through using foreach like.
foreach($decoded as $de){
// access id with $de['id']
// access value with $de['value']
}
You have got an json string. You can convert it to an array by using function json_decode
Check this code .
$str = '[{"id":"17","value":"123456789"},{"id":"18","value":"2012-06-13"}, {"id":"19","value":"Kampala"},{"id":"20","value":"1"},{"id":"21","value":"500g"},{"id":"22","value":"Emirrets"},{"id":"23","value":"q"},{"id":"24","value":"q"},{"id":"25","value":"q"},{"id":"26","value":"q"},{"id":"27","value":"q"},{"id":"28","value":"q"},{"id":"29","value":"2"},{"id":"30","value":"987654321"},{"id":"45","value":"1"},{"id":"46","value":"1"}]';
$array = json_decode($str);
foreach($array as $temp){
echo "ID : ".$temp->id."\t Value: ".$temp->value;
echo "<br />";
}
I have this code:
$id = new matrix(array(0=>array(1,0.5,3), 1=>array(2,1,4), 2=>array(1/3,1/4,1)));
$soma = $id->times($id)->sumRows();
That outputs this:
matrix Object ( [numbers] => Array ( [0] => Array ( [0] => 12.75 [1] => 22.3333333333 [2] => 4.83333333333 ) ) [numColumns] => 3 [numRows] => 1 )
and:
$total = $id->times($id)->sumRows()->sumTotal($id);
That outputs this:
matrix Object ( [numbers] => Array ( [0] => Array ( [0] => 39.9166666667 ) ) [numColumns] => 3 [numRows] => 1 )
Now, i am trying to make:
foreach ($soma as $value){
$final = (int)$value/(int)$total;
print_r ((int)$final);
}
The output will be 000.
Must be:
12.75/39.9166666667 = 0,3269230769230769
22.3333333333 / 39.9166666667 = ...
and so on
Thanks!
Just some ideas, without really knowing much about the matrix class...
All those (int)s should probably be (float)s, as you seem to want a non-int answer.
$value is itself an object, so you'll probably need to use $value['numbers'][0][0 or 1 or 2]. Same goes for $total.
the issue is solved :
