what I want is delete unset array value and update json object aswell.
foreach ($gdUrl_data as $key => $value) {
$vpstgcount = count($value["vls"]["pstsg"]);
for ($j = 0; $j <$vpstgcount; $j++) {
$minVal = $value["vls"]["pstsg"][$j]["min"];
if ($minVal == 0)
{
unset($value["vls"]["pstsg"][$j]);
}
}
}
$gdUrl_data = json_encode($gdUrl_data);
this will unset the array but not update the json .
function unsetKey($json, $key) {
$json = json_decode($json, true);
unset($json[$key]);
return json_encode($json);
}
$value is a copy of the array element, so when you unset parts of it you're not affecting the original array. If you want it to be the actual array element, use a reference variable:
foreach ($gdUrl_data as &$value) {
foreach ($value["vls"]["pstg"] as $j => $el) {
if ($el["min"] == 0) {
unset($value[$j]);
}
}
}
