学习PHP字符串逆转

Question

$original = "test";
$reversed = strrev($original)
echo "Original String: $original";
echo "Reversed String: $reversed";

我正在学习php，为什么上面的脚本给出此错误：

Parse error: syntax error, unexpected 'echo' (T_ECHO) index.php : eval()'d code on line 3

Answer 1

您缺少半隆：

$reversed = strrev($original);
