如何在PHP中显示htmlspecialchars

Question

我将如何使用PHP使其准确显示呢？

$answer=<script>alert(It converts to HTML.)</script> 
echo "The function is: htmlspecialchars ($answer)."

Answer 1

$variable = <<<'EOS'
$answer=<script>alert(It converts to HTML.)</script> 
echo "The function is: htmlspecialchars ($answer)."
EOS;
echo htmlspecialchars($variable);

这将显示与您键入的消息完全相同的消息。

Answer 2

$answer = "<script>alert(It converts to HTML.)</script>"

echo "The function is: htmlspecialchars".$answer;
