Hello friend, I have a small PHP exercise in which I have to request the user's name and tell him how many words have his full name and that's it.
but I do not constrict it I have this following code:
$textosolicitado = print "var nombre= prompt('cual es tu nombre');";
echo "Tu nombre tiene:";
echo str_word_count($textosolicitado);//will return the number of words in a string
You can use str_word_count , available from PHP version 4, and 5 and 7.
The function receives as your first parameter your string , as second an optional value to return only the count of the words 0 or default nothing, 1 returns an array with all the words found and their order, and 2 that also returns an array but that shows the words found and the position in which it is inside the string you passed.
Like this:
php > echo str_word_count('Hello world!');
2
With a value 1 as formato :
php > print_r(str_word_count('Hello world!', 1));
Array
(
[0] => Hello
[1] => world
)
Passing 2 , this time shows the position within your string where the second word starts:
php > print_r(str_word_count('Hello world!', 2));
Array
(
[0] => Hello
[6] => world
)
The third and optional parameter is the charlist that can be used to add an additional list of characters that will be used as words.
