I am wanting to change words in a string that has special tags.
Ex. "This is a %/i%special%i% word in the string."
If I want to replace any word between the %/i% and %i% what would I do?

I messed with preg_repace but I couldn't understand the pattern system.

What have you tried so far? Do you have any experiences with regular
expressions?

I have tried many things but all return errors - mostly "unknown modifier".

Which means syntax error.

Please post your code.

I was trying to just first get it to replace the exact thing typed. Then 
move on to replacing any word within the %/i% and %i%

     $Scripture="this is a %/i%test%i%";
     preg_replace("%/i%test%i%","XXXXXXXX",$Scripture);

This errors with Unknown modifier t
I tried what I thought was escaping it by putting a \test but that just 
messes up more. See I haven't a clue.

Since this function seems to elude me I simply wrote a samll function to 
do what I want. I simply pass it the two needles, haystack and what I 
want to replace with.

Thanks

http://php.net/manual/en/regexp.reference.delimiters.php

When you use a regex, the first character inside your quotes is taken as 
the pattern delimiter.

In your case, this is a "%" character.

The format of a regex string is:

"delimiter pattern delimiter optional-modifiers"

Hence, "%/i%t" is the pattern "/i" with the modifier "t"

Try:

preg_replace("!%/i%test%i%!","XXXXXXXX",$Scripture);

This will use the "!" character as the pattern delimiter and should, in 
this specific case, solve your problem. Generally it's a good idea to 
pick a pattern delimiter that does not have special meaning to regex and 
is not part of your data. This isn't always easy.
