how to know how many words has a String in php?

  • 772

Hello friend, I have a small PHP exercise in which I have to request the user's name and tell him how many words his full name has and that's it.

but I do not know it, I have this following code:

$requestedtext = print "var name= prompt('what's your name');";


echo "Your name has:";
echo str_word_count($textrequested);//will return the number of words in a string
php

    You can use str_word_count, available since PHP version 4, and in 5 and 7.

    The function receives as the first parameter your string, as the second an optional value to return only the word count 0or by default nothing, it 1returns an array with all the words found and their order, and 2which also returns an array but shows the words found and the position at which it is found within the string which you passed.

    Thus:

    php > echo str_word_count('Hello world!');
2

    With a value 1like formato:

    php > print_r(str_word_count('Hello world!', 1));
Array
(
    [0] => Hello
    [1] => world
)

    Passing 2, this time shows the position within your stringwhere the second word begins:

    php > print_r(str_word_count('Hello world!', 2));
Array
(
    [0] => Hello
    [6] => world
)

    The third and also optional parameter is the charlistone that can be used to add an additional list of characters that will be used as words.
