This question already has an answer here:
I just start to learn PHP, but I can't to make a easy problem. Can you help me and after say why my problem doesn't work? Here is the problem:
- Create a new variable $name and store your name in it.
- Then print a random character from your name. Use your knowledge of strlen(string), rand(min, max), and substr(string, start, length) to do this.
HINT: Remember that substr() treats characters in a string as a zero-indexed array (first letter is at position zero). This means that the last character in the string will be at position length - 1.
I try but without result.
<html>
<p>
<?php
$name = "George";
$fl = substr($name, 0, strlen($name));
$sl = substr($name, 0, 1);
print rand($fl,$sl);
?>
</p>
</html>
I think problem is at rand...I can't randomise items with id or something?I can print the $sl or $fl ..
</div>
It can be done like this:
<?php
$name = "George";
$nameLength = strlen($name);
$randomNumber = rand(0, $nameLength - 1);
$randomLetter = substr($name, $randomNumber, 1);
echo $randomLetter;
?>
