Parsing and replacing in PHP

Re: Parsing and replacing in PHP

Easiest way is to use a perl regular expression search and replace.

Something like this?

Thanks, that was helpful for the thing that I am working on, too.

However, maybe you can answer this - if I have a string formatted into a
variable, say $strip_it, which is:

$strip_it = "http://www.someaddress .com/somepage";

....and I wanted to strip this out of a whole page of code where it appeared
multiple times, how would you set the values?

From your example (note I am using PHP 4.4, so no count parameter):

  $search  = $strip_it;
  $replace = ""; // replace with nothing

  $result = preg_replace( $search, $replace, $initial_html, -1, );

I can't figure out how to set up $search - I keep getting different
errors...

Yeah, you would get errors since $strip_it contains the '/' characters.
They have special meaning for the preg functions. If you ever become
interested, learn all about regular expressions. They are very fun!

In order to just remove $strip_it from all the text, try the
str_replace function. It'll be faster, too.

$result = str_replace( $strip_it, '', $initial_html );
