You can take reference form below example to fetch data from array list using php.

This method is really very easy.

<?php

// you have to Decode the array and store a variable
$GetRecord = json_decode('[{"Name":"Mac","age":"25"},{"Name":"Warner","age":"30"},{"Name":"Cris","age":"22"},{"Name":"Broad", "age":"40"},{"Name":"Joe","age":""}]');


// Loop for find the array value
foreach ($GetRecord as $key => $value) {

    if ($value->Name == Mac && ($value->age == 25 ))
     {

        echo 'success-! Record found ';
        exit;
    }else{
         echo ' Error-! Record not found';
         exit;
    }
}

?>

If name and age exist in given array list then result will come "success-! Record found". If name and age not exist in given array list then result will come "Error-! Record not found".
