PHP Invisible string

Question

I have this array of string:

array(59) {
    [0]=> string(25) "shadowcores.twifysoft.net"
    [1]=> string(11) " "
}

Obviously there are 57 elements more. I need to know how can I remove this:

string(11) " "

There is no string to display but the string itself its not empty. How can I check for these types of values before adding them into my array?

Answer 1

Use the following:

$array = array_filter($yourArray, 'trim');
