PHP Three solutions for removing HTMl tags

Method 1:
Take out the mark you want directly

<?php
    // Take out the br tag 
    function strip($str)
{
$str=str_replace("&lt;br&gt;","",$str);
//$str=htmlspecialchars($str);
return strip_tags($str);
}
?>

Method 2.
There is an strip_tags function in PHP to conveniently remove HTML tags.
echo strip_tags (" Hello < b > World < /b > "); // Remove HTML, XML and PHP labels.
Non-standard HTML code can also be removed correctly:
echo strip_tags (" < a href = \" > \" > cftea < /a > "); / / output cftea
In PHP, you can use the strip_tags function to remove the HTML tag, as shown in the following example:

<?php
$str =  ' www<p>dreamdu</p>.com';
echo(htmlspecialchars($str). " <br> " );
echo(strip_tags($str));
?>
