[Resolved] How to get the word out of a long string

[sunnyside]

I have a string which contains many words. This string is created by another function which inside by using "<br>" to create new line for each word.

Result Example:
I
am
a
student

I would like to get each word out of this string by using a function get one word each time.

something like: get_word($str, $num);
when $num=1, return "I";
when $num=2, return "am";
when $num=3, return "a";

thank you for your help!

This could work...

function get_word($string, $num) {
   $string = str_replace('<br />', ' ', $string);
   $array  = str_word_count($string, 1);
   return array_key_exists($num, $array) ? $array[$num] : NULL;
}

Use explode() to convert the string into an array and then access any element by number-1.

$ary = explode("<br />", $str);
//will cut into words using the html <br /> tags to seperate each word

function get_word($str, $num) {
   $ary = explode("<br />", $str);
   $i = $num-1;
   return $ary[$i];
}
