How do I escape angle brackets?

[Mxsmanic]

I have a line like this in some PHP code on my Web page:

$callthis =~ s/<[^>]*>//g;

When the page runs, I get this error:

Parse error: parse error, unexpected '<' in /Feedback.php on line 145

So I presume I must escape angle brackets somehow in the regular
expression. How do I do it? I tried putting a backslash in front of
each angle bracket, but that doesn't seem to work (same error).

The purpose of the statement is to remove HTML tags from the string.

That doesn't look like any PHP code that I know.
Use the function strip_tags() to strip HTML from strings.

Looks like Perl to me.

With a \ but I doubt that's the problem.

That's because it's not PHP.

Try this: $callthis = preg_replace("/<[^>]*>/", "", $callthis);

Try using the strip_tags() function: http://www.php.net/strip_tags

Doesn't PHP support substitution with regular expressions?

I'm always getting confused between Perl and PHP.

Thanks, I'll do that instead.

It would work in Perl. Doesn't PHP support regular expressions? I can
never remember which language supports what.

Done, and it works. Thanks.

Yes, PHP does support regular expressions. I gave you the code for it.
Here it is again:

$callthis = preg_replace("/<[^>]*>/", "", $callthis);

I just wanted to add that the code looks like perl.

this is because you've tried to use a PERL expression. in PHP, you'd
do something more like this:

$callthis = preg_replace("\<[^\>]*\>","",$callthis);

but as another poster mentioned, PHP already has a function for the
purpose you specified.

hope that clears things up for you.
