$get_result[] = ['ID' => $get_data['ID'], 'username' => $get_data['username']];
$return = "true";
}
}
if($return = "false"){
echo false;
}
}

Answer 1

If I understood well your question (I'm not sure), this should work:
foreach($array2 as $array) {
foreach($array1 as $get_data) {
if($array1['media_id'] == $get_data['media_id'] && $array1['userid'] == $get_data['userid']) {
$get_result[] = ['ID' => $get_data['ID'], 'username' => $get_data['username']];
}
}
}
if (count($get_result) == 0) {
$get_result[] = false;
}

Not sure about your real needs, but #gmc gave you (part of ? all ?) what you need IMHO
<?php
$array1 = array (
0 => array ( "ID" => "335", "userid" => "4", "username" => "demo", "media_id" => "117" ),
1 => array ( "ID" => "436", "userid" => "4", "username" => "demo", "media_id" => "118" ),
2 => array ( "ID" => "637", "userid" => "4", "username" => "demo", "media_id" => "19" ),
3 => array ( "ID" => "838", "userid" => "4", "username" => "demo", "media_id" => "20" )
);
$array2 = array (
1 => array ( "ID" => "35", "userid" => "4", "media_id" => "17" ),
2 => array ( "ID" => "36", "userid" => "4", "media_id" => "18" )
);
$get_result = array();
foreach($array2 as $array) {
foreach($array1 as $get_data) {
if( ($array['media_id'] == $get_data['media_id']) && ($array['userid'] == $get_data['userid'])) {
$get_result[] = ['ID' => $get_data['ID'], 'username' => $get_data['username']];
}
}
}
if (count($get_result) == 0) {
echo"false";
}
else {
echo"true"; print_r($get_result); }
?>
/* I modified values to 117 & 118 -> returns "false" */
/* If you set values to 17 & 18 -> returns "true" */
