is there a way to avoid "undefined index" error? (refer the code on description)

Question

<form method="post">
<input type="text" name="title" /> <br />
<input type="text" name="link" /> <br />
<input type="text" name="content" /> <br />
<input type="text" name="hashtags" /> <br />
<button type="submit" name="submit">Submit</button>
</form>

<?php
echo $_POST['title'];
?>

// to run the code without "undefined index error" i used if statement
if (!isset($_POST['title']) {
echo null;
} else {
echo $_POST['title'];
}
// is there a better way to do this?

Answer 1

you can use the error control operator "@" like that:
<?php
echo @$_POST['title'];
?>
