removing HTML code

[webguync]

How can HTML code be removed with PHP in an example such as below?

 

$string = "<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>"; 

[papaface]

<?php
$string = '<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>';
echo strip_tags($string);
?>

[waynew]

Or

 

$string = htmlentities("<span style=\"font-size:10px; font-weight:bold;\">Hello <em>World</em></span>");
echo $string;

What those guys mean is that you have to think the opposite way. Don't search to remove lines, you have to tell the code to NOT show it

[papaface]

Or

 

$string = htmlentities("<span style=\"font-size:10px; font-weight:bold;\">Hello <em>World</em></span>");
echo $string;

 

 

That will produce:

<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>

which is not what the OP wants.

[waynew]

No. That will produce:

 

<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>

[papaface]

No. That will produce:

 

<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>

Exactly, its not actually stripping the html tags at all. Its just replacing them with the entities.

[waynew]

He never said anything about stripping tags. He said "remove html". Which is what htmlentities( ) will do.

 

<span style="font-size:10px; font-weight:bold;">Hello <em>World</em></span>

 

is not html.

I think you'll find it is HTML but in its raw form. I think everyone else will agree with me that you're not actually removing anything at all. The OP should clarify.

It's not HTML? How is it HTML in it's raw form? It's been turned into something that will be printed on screen instead of interpreted as HTML?

[waynew]

This function is identical to htmlspecialchars() in all ways, except with htmlentities(), all characters which have HTML character entity equivalents are translated into these entities.

I think the point of the OPs post is to not allow people to post HTML tags to his/her script. I think we're deviating from the subject a bit. The facts of the matter are that the OP did not ask for the HTML to be shown in entity form,. but he DID ask for the HTML to be removed, which I think I have provided the code for.

With htmlentities, they're not posting HTML tags. htmlentities( ) removes HTML.

ok

We've wasted our time arguing over what car drives.  :-\

sorry to cause such a stir!

FWIW I did mean how to strip out the HTML code entirely, so papaface had the response that worked. I know it's an unusual question, but I just wanted to know how it was done in PHP.
