You can use array_map, if you have fixed keys:

<?php

$category = array('available', 'notavailable' );
$values = array(1, 2 );

$array = array_map(function($category, $value) {
    return ['category' => $category, 'value'=>$value];
}, $category, $values);

echo "<pre>";
var_dump(json_encode($array));
echo "</pre>";

Output:

string(74) "[{"category":"available","value":1},{"category":"notavailable","value":2}]"
