Check if specific array value isset PHP

Question

I have a slider for news items and doing a loop to get post info for each. Works fine but I am stuck with one paramater that is returned by json and I loop trough it again . the $xtras parameter returns some additional values one of them is additional intro text. I need to check if this value isset otherwise I need to return default intro text.

problem I have is that if $xtra_values->id 44 does not exists I get the intro text from previous post instead that post $post['intro']

$xtras returns stdClass Object like this

stdClass Object
(
    [id] => 1
    [value] => 38
)
stdClass Object
(
    [id] => 28
    [value] => 1
)
stdClass Object
(
    [id] => 44
    [value] => This is extra intro text
)

and this is my loop

foreach ($post_array as $key=> $posts){

    $xtras  = json_decode($posts['xtra']);

     foreach($xtras as $key=> $xtra_values){

        if($xtra_values->id == 44){
           $intro_text = $xtra_values->value;
        }else{
           $intro_text = $post['intro'];
        }     

     }




      echo $post['title'];.'<br />';
      echo $intro_text;
}

Any help is appreciated. Thank you!

foreach ($post_array as $key=> $posts){

$xtras  = json_decode($posts['xtra']);
$intro_text = null;


 foreach($xtras as $key=> $xtra_values){

    if($xtra_values->id == 44){
       $intro_text = $xtra_values->value;
    }     

 }
if($intro_text == null){
       $intro_text = $post['intro'];
    }

same as from mgraph , does not work and $xtra_values->id is always set since it returns more than 1 stdClass Object, in both cases now I get only $post[intro]

is $xtra_values an array of StdClasses?

worenga Over a year ago

foreach($xtras as $key $xtra_values){ to foreach($xtras as $key => $xtra_values){ typo?

Benn Over a year ago

yes just typo , what I need is to check if $xtra_values->id == 44 is set , not if $xtra_values->id is set but dont know how to check for that only

Benn Over a year ago

try:

if(isset($xtra_values->id) && $xtra_values->id >= 0 && $xtra_values->id == 44){
