where do i start


#1

i need help on where to start with the following question. Is a loop required.

Using your knowledge of ASCII character sets and If-Else, create a PHP application that will read through every character of a stored string, by a using a suitable loop, and will count the number of @ characters found in the string. (Note: the ASCII value for the @ character = 64). The number of @ characters found should be displayed on screen (even if none were found). To help you achieve this you may need to count the number of characters in the string.
