    Little function like If $variable == 0 then echo "--"

    Actually - if you had saved the formatted number before doing the entire echo statements you probably would not be seeing the -- since the formatted resulted would be a string and therefore <>  to a numeric zero.  But you didn't.

    i have both when it's 0. 0--. And i try to hide the 0 when the result is zero. I want to replace it with --.

    1 - do not write code like you just presented to us.  Use separate lines for each statement.  You won't regret it.

    2 - you should not have to enter and exit php mode for a couple lines of php code.  Unless you are poorly structuring your script.  So - break that habit.

    3 - You are asking us to give you an explanation yet we don't know WTH your code is doing to the $max_supply variable.  Are you kidding?

    max_supply is a number. what else? maybe you should go for a forum only for solutions. i will ask somewhere else for help.

    format numbers with a helper / function

    in PHP Coding Help

    Posted · Edited by paulmagm 

    function price_format($price, $decimals = 2) {
    $CI =& get_instance();
    $config = $CI->config->item('mcp');

    $price = (float) $price;
    $formats = ["US" => ['.', ','], "EU" => [',', '.']];
    $decimals = ($price >= 1 || $price == 0) ? $decimals : ($price < 0.000001 ? 8 : 6);
    return number_format($price, $decimals, $formats[$config['num_format']][0], $formats[$config['num_format']][1]);

$coinfeed_coingecko_json = file_get_contents('https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd&ids='.$t['page.content_slug'].'');
$coinfeed_json = json_decode($coinfeed_coingecko_json, false);
$coinfeed_current_price = $coinfeed_json[0]->current_price;
$coinfeed_current_supply = $coinfeed_json[0]->circulating_supply;
$coinfeedprice_change_percentage_24h = $coinfeed_json[0]->price_change_percentage_24h;
$coinfeed_ath = $coinfeed_json[0]->ath;

?>

<?php  echo $coinfeedde = number_format($coinfeed_current_price, 0, '.', '.');  ?>

     

    I created my first api call and now i trying to connect it to my old numbers helper (function price_format).
    How can i connect this function with my new api call? If i replace $price it will not work. Thanks for your time guys.

     <?php 
 
ini_set('max_execution_time', 300);
// $tick = file_get_contents('https://api.coinmarketcap.com/v1/ticker/bitcoin/');
$url ='https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest?limit=2000';// path to your JSON file
$data = file_get_contents($url); // put the contents of the file into a variable
$characters = json_decode($data); // decode the JSON feed
$api_key = 'API KEY';

// echo $characters[0]->name;

foreach ($characters as $character) {
echo '<tr>';
  
echo '<td>' . $character->{'24h_volume_usd'} . '</td>';

echo '</tr></tbody>sdsdf</table>';
}
?>

    The first argument I simply made a change to.  The second arg I added the function to the var you were passing into the function.  Pretty simple, huh?  Of course I am assuming that your var is actually a string.  Correct?

    Now it works. Thank you very much!

    Because of the semi-colon at the end of each declaration and those being declared inside $data.

    You would need to move them outside like so: 

    $content_slug = ucfirst($page['content_slug']);
$content_title = ucfirst($page['content_title']);
$data = [
	'title' => "{$content_slug} ({$content_title}) ",
	'meta.description' => $description,
	'page' => $page,
];
return $app->render($template, $data);
}

     

    That works now. Thank you very much!

    Thanks make sense. But crashed my site. But why? This is the hole context then. 

      $data = [
            $content_slug = ucfirst($page['content_slug']);
            $content_title = ucfirst($page['content_title']);
            'title' => "{$content_slug} ({$content_title}) ",
            'meta.description' => $description,
            'page' => $page,
        ];

        return $app->render($template, $data);
    }

    <progress value="document.getElementById('demo')" max="1000"> <script> document.getElementById("demo").innerHTML = document.querySelector('progress').value = (100 + 50) * 3; </script>
