Hi there so the The PHP strpos() function searches for a specific text within a string. If a match is found, the function returns the character position of the first match. If no match is found, it will return FALSE. The example below searches for the text "world" in the string "Hello world!": source: https://www.w3schools.com/php/php_string.asp but if I did this thing Code (PHP): <?php echo strpos("Hello world!", "world"); ?> the output is 6 since it will find the specific text within a string it will be 8 for me double ll in "heLLo" and one o in hellO" the rest is in the word "world" or I'm wrong in analyzing the explanation. My native language is not english so explain in simple worlds thank you.
