Count all word including numbers in a php string

Question

To count words in a php string usually we can use str_word_count but I think not always a good solution

good example:

$var =\"Hello world!\";
echo str_         


        

Answer 1

Just some improvement your solution

function stringWordNumberCount($text){
    if (!$text) {
        return 0;
    }

    //Clean the text to remove special character
    $text = trim(preg_replace('/[^A-Za-z0-9\-]/', ' ', $text));

    //Remove continus space on text
    $text = trim( preg_replace('/\s+/', ' ',$text));

    //count space
    return count(explode(' ', $text));

}
