is_associative function?

[Jak-S]

Hi,

Ok, so I know this function doesn’t exist, but is there an equivalent? Something that will return true or false and tell me if an array is associative?

Thanks,

Jack

Associative keys are string keys. This function will check if there is at least one string kay and return true if there is one.

PHP Code:

function is_associative($array)
{
    if(!is_array($array))
    {
        return false;
    }
    krsort($array, SORT_STRING);
    return !is_numeric(key($array));
}

Cool, cheers, i had just thrown this together, which works, but i should imagine yours is better as it dosent actually loop through the array, so i guess it would be faster?

PHP Code:


function is_associative($input) {

    $result = false;
    
    foreach($input as $key => $value) {
        if(is_string($key)) {
            $result = true;
            break;
        }
    }
    
    return $result;

} 


Thanks!
