The example in this article describes how PHP simply handles special characters entered in a form. Share it with everyone for your reference, the details are as follows:
<html>
<body>
<?php
if ($_POST['submitted'] == "yes"){
$yourname = $_POST['yourname'];
$yourname = trim ($yourname);
$yourname = strip_tags ($yourname);
$yourname = htmlspecialchars ($yourname);
$yourname = addslashes ($yourname);
echo $yourname . "<br />";
?><a href="index.php">Try Again</a><?php
}
if ($_POST['submitted'] != "yes"){
?>
<form action="index.php" method="post">
<p>Example:</p>
<input type="hidden" name="submitted" value="yes" />
Your Name: <input type="text" name="yourname" maxlength="150" /><br />
<input type="submit" value="Submit" />
</form>
<?php
}
?>
</div>
</body>
</html>
