PHP: count number of words in a string
Count the number of elements in a string using the count() and explode() commands. By specifying a delimiter you can also use this technique to break apart file paths and comma seperated lists.
code snippet:
<?php
$delim = " ";
$string = "One point twenty one gigawatts?";
$words = count(explode($delim, $string));
echo "The string contains $words elements.";
?>
sample output:
The string contains 5 elements.
notes:
By providing a delimiter and a string, the explode command returns an array of elements. The count command returns an integer with the number of elements in an array.
