What causes 'unexpected t_exit' in php?

Example:

if ($x > 10) 
exit();
echo "Hello";

You might encounter this error when using the 'exit' function without braces in an 'if' statement, and having a statement after it.

Solution:

Use braces for the 'if' condition or ensure correct structure.

if ($x > 10) {
    exit();
}
echo "Hello";
