Keine Rückgabe einer Zählnummer für gefülltes Array

Question

$arrg = array();
if( str_word_count( $str ) > 1 ) {
    $input_arr = explode(' ', $str);
    die(print_r($input_arr));
    $count = count($input_arr);
    die($count);

oben ist Teil einer Funktion. Wenn ich es ausführe, erhalte ich;

Array (
    \[0\] => luke
    \[1\] => snowden
    \[2\] => create
    \[3\] => develop
    \[4\] => web
    \[5\] => applications
    \[6\] => sites
    \[7\] => alse
    \[8\] => dab
    \[9\] => hand
    \[10\] => design
    \[11\] => love
    \[12\] => helping
    \[13\] => business
    \[14\] => thrive
    \[15\] => latest
    \[16\] => industry
    \[17\] => developer
    \[18\] => act
    \[19\] => designs
    \[20\] => php
    \[21\] => mysql
    \[22\] => jquery
    \[23\] => ajax
    \[24\] => xhtml
    \[25\] => css
    \[26\] => de
    \[27\] => montfont
    \[28\] => award
    \[29\] => advanced
    \[30\] => programming
    \[31\] => taught
    \[32\] => development
    \[33\] => years
    \[34\] => experience
    \[35\] => topic
    \[36\] => fully
    \[37\] => qualified
    \[38\] => electrician
    \[39\] => city
    \[40\] => amp
    \[41\] => guilds
    \[42\] => level )

Was ich erwarte;

ausführen, aber es wird nichts zurückgegeben:

$arrg = array();
if( str_word_count( $str ) > 1 ) {
    $input_arr = explode(' ', $str);
    //die(print_r($input_arr));
    $count = count($input_arr);
    die($count);
