Trying to spit sentence into array with words - php

Question

I am trying to split a sentence into an array with words, one word as each element, in PHP if there is more than one word in the sentence. If there is only one word in the sentence, then I just print that one word.
My issue is when I split the sentence into words delimited by a space and put the contents into an array. I do this all using explode. But when I run through the array that explode apparently makes, it says there is nothing in the array when I try to print each item.
Here is my code:
if(isset($_GET['check'])){
$input = trim($_GET['check']);
$sentence='';
if(stripos($input, ' ')!==false){
$sentence = explode(' ', $input);
foreach($sentence as $item){
echo $item;
}
}
else{
echo $input;
}
}
Why is echo $item; printing nothing? Why isn't there anything in the array $sentence?

Your code seems to be working fine. Make sure you're getting the variable. You can do a print_r($_GET);
You can also just do this:
<?php
$_GET['check'] = 'Hey how are you?';
if (isset($_GET['check'])) {
// each word is now an element in the array
$arr = explode(' ', trim($_GET['check']));
}
// piece each word back together with a space
echo implode(' ', $arr);
?>
It doesn't matter if it's a single word or multiple words.
UPDATE: If you really want to check if the user has entered one word or more than one word you can do this:
<?php
$_GET['check'] = 'Hey how are you?';
if (str_word_count($_GET['check']) > 1) {
echo 'More than one word';
} else {
echo 'Only one word';
}
?>
Check out str_word_count
