Delete an element from curl-json

I can get data from a website with CURL and I can convert this data to json.

I want to remove an element from json.

Output:

{
        "test":{
            "numbers":
                [
                       "1",
                       "27",
                       "32",
                       "1",
                       "94",
                       "1",
                       "8"
                ]
        }
}

I want to remove "1" from my json. How can I do that? Thank you for your help.

my code:

<?php
function Curlconnect($start,$end,$website) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $website);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $website = curl_exec($ch);
    preg_match_all('@'.$start.'(.*?)'.$end.'@si',$website,$ver);
    return $ver[1];
    curl_close($ch);
}

function nt($start,$bit,$data,$a) {
    preg_match_all('@'.$start.'(.*?)'.$bit.'@si',$data,$ver);
    return $ver[1];
}

$url = 'http://www.url.com';
$getdata  = Curlconnect('<h4','h4>',$url);
$jsonData = ["data"];
$jsonData["numbers"] = [];
for ($a=0; $a<count($getdata); $a++) {
    $printdata = nt('>','</',$getdata[$a],$a);
    $jsonData["test"]["numbers"][] = $printdata[0];
}

echo json_encode($jsonData);
?>

You can use array_search() to look for a value in an array (your $jsonData["test"]["numbers"] array), and use unset() to remove the value from the array.

Because there are multiple "1" values, and array_search() only returns the first key found, you'll need to use a while loop to ensure you find all the values to remove.

function remove_value_from_array ($val, $array)
{
    while ( ($key = array_search($array, $val)) !== false)
    {
        unset($array[$key]);
    }

    return $array;
}

$jsonData["test"]["numbers"] = remove_value_from_array($jsonData["test"]["numbers"], "1");

Edit: I've remembered a simpler way - and a way that allow you to search for multiple values. You can simply use array_diff() to search for values, and remove them.

// Remove a single value of "1"
$jsonData["test"]["numbers"] = array_diff($jsonData["test"]["numbers"], array(1));

// Remove multiple values, of "1", "2", "5", and the word "test"
$jsonData["test"]["numbers"] = array_diff($jsonData["test"]["numbers"], array(1, 2, 5, "test"));
