I try to solve this exercise, but Im not sure how to look for the solution. For my current knowledge my program should print out smg, but I get only error .
Error message :
Warning: Undefined variable $x in /in/NVFqg on line 6
Charile bit your finger!
Here is my code :
<?php
function isBitten()
{
if ($x <= 50) { // line 6 //
echo "Charile bit your finger!";
$x = rand(0, 100);
}
else {
echo "Charlie did not bite your finger";
}
}
?>
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>Charlie</title>
</head>
<body>
<?php
isBitten();
?>
</body>
</html>
Your help is much appreciated! Thank you!
