Answer 1

Explode your string with spaces (which will create an array with all words), then check if the word is bigger than 4 letters.

//The string you want to explode
$string = "Sus azahares presentan gruesos pétalos blancos teñidos de rosa o violáceo en la parte externa, con numerosos estambres."
//explode your $string, which will create an array which we will call $words
$words = explode(' ', $string);

//for each $word in $words
foreach($words as $word)
{
    //check if $word length if larger then 4
    if(strlen($word) > 4)
    {
        //echo the $word
        echo $word;
    }
}

strlen();

strlen — Get string length

explode();

explode — Split a string by string
