php数组是空的不行

I have a dynamically generated array. sometimes it's value is null, when it is null the browser gives an error. therefore I want to check if the array is empty. when array is empty i use

echo var_dump($myarray); 

then browser echoing following

i want to identify this kind of situation i use

  array(0) { } 

i try flowing method but it didn't work

$errors = array_filter($myarray);
if( !empty($errors)){
       //do 
}

also i try

if ($myarray==''){
 //not working
}

    You don't have to use array_filter. You can simply check for array being empty this way:

    if(empty($myarray)){
        // Code to execute when array is empty.
    }
    else {
        // Code to execute when array is not empty.
    }
