How to use str_ireplace() and strlen() Functions In PHP
Another approach is to replace all vowels in the string with an empty string using str_ireplace and then calculate the length of the resulting string.
Example: The below example illustrates the total Count of the Number of Vowels in a String using str_ireplace() and strlen() Functions.
PHP
<?php function countVowels($str) { $strWithoutVowels = str_ireplace(["a", "e", "i", "o", "u"], "", $str); return strlen($str) - strlen($strWithoutVowels); } // Driver code $str = "w3wiki"; $vowelsCount = countVowels($str); echo "Number of vowels: " . $vowelsCount; ?> |
Output
Number of vowels: 5
