What is the purpose of using the explode function in PHP when trying to determine the character count of a text area input without spaces?

The explode function in PHP can be used to split a string into an array based on a specified delimiter. By using the explode function with an empty space delimiter on the text area input, we can separate the words and then count the characters in each word to determine the character count without spaces.

$text = $_POST['text_area_input'];
$words = explode(" ", $text);
$charCount = 0;

foreach ($words as $word) {
    $charCount += strlen($word);
}

echo "Character count without spaces: " . $charCount;
