I want to see if an item with a specific "name" key, (for example "Fervor ADC") exists in it, in order to use it for a membership verification. How can I look for it knowing that the array can have more values? The [0] to [4] here are the number of pages and it varies from 1 to 20.

Answer 1

//Will comes to know value exist or not in array
echo in_array_r("Fervor ADC", $array) ? 'found' : 'not found';
//function to find a value exist or not in array.
function in_array_r($needle, $haystack, $strict = false) {
foreach ($haystack as $item) {
if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) {
return true;
}
}
return false;
}

Answer 2

Initialize a result and search term
$result = null;
$searchName = "Fervor ADC"
Loop over the values in the 'pages' key:
foreach ($your_array['36694730']['pages'] as $x) {
// if you find one that matches your search term, set your result to that one
if ($x['name'] == $searchName) {
$result = $x;
// then stop the loop; you're done.
break;
}
}
Then if you just want to verify that it exists
if ($result)
will work. And if you end up needing to do anything else with the data associated with that name, then you'll have it available in $result.
