[RESOLVED] How to remove and with preg

rtcary

Still struggling with preg patterns. I want to remove "" and "" tags from the text. This creates an error:

preg_replace ('/[]|[]/', '', $str)

as well as

preg_replace ('/|/', '', $str)

Also, if there is a good online tutorial, I would appreciate the reference. My Googling brought many, but of those that I examined, they did not go into much depth.

'#</?p>#'

I'm using "#" as the pattern delimiter so I don't have to escape the "/" in the actual regexp, and the "?" to indicate that there may be zero or one "/".

However, understanding the underlying requirement for doing this might lead to other solutions, such as using strip_tags(), or a more complex regexp if you need to cope with attributes within the tag, white-space, etc.

Have you tried this tutorial?

<?php
$A = '<p>abc</p><p>123</p>';
echo preg_replace('/<p>(.*?)<\/p>/','\\1', $A);
?>

Since the source of the string (html page) can have \n's in the string, this does not work:

preg_replace('/(.*?)<\/p>/','\1', $A);

However, I am only guessing about the \n's since I am still trying to learn about Pattern creation. The string that was being replaced prints as follows when debugging:

This pattern does work:

preg_replace('#</?p>#','', $A);

I greatly appreciate the help, yet I wish I could pop these patterns out with the ease that you appear to have.

The former pattern will work if you add the 's' modifier to the regexp pattern.

Spend a few months some time writing Perl scripts to parse log files, and then you'll get the hang of it. 😉

Also, instead of your girlfriend, play with this. That's what I did.

Needless to say, my girlfriend left me... :rolleyes:

And now you're grep'ing for a new one? 😃
