Hi!
I have managed to live without using too much regular expressions so
far, and now that I need one, I need some help too.
I have a string containing a (possibly large) block of html. I need to
insert code (an image to be precise) right after the last textual
character in the string. This is, of course, no problem if the end
contains plain text and no html. If the string ends in HTML however, I
need to fiddle around. for example consider that the string ends like
"... lorem ipsum.</p></blockquote>". I need to insert code between
"ipsum." and "</p>".
So what kind of regular expression I need, or is there another way I
have missed, to insert code into the string, right after the last
visible character, but before the possibly following html tags (usually
ending tags such as the mentioned </p> and </blockquote>).
Thank you in advance.

a bit of a guess I'm afraid

Hi Juha, James
I tested the regular expression written by James and found it
incorrect. This expression inserts the repalcement code before all
instances of <\.
The correct one is as follows:
$replacement = "\$1you_code_he re\$2\$3";
$newStr = preg_replace("/(.*)(\<\/)(.*)$/s", $replacement, $str);

Thanks for the tips.

Actually this does not work as I wished either. This works fine if the
textblock ends in a single closing html tag, but does not work correctly
if there are several:
string "..lorem ipsum dolor</p></blockquote>"
becomes "..lorem ipsum dolor</p>you_code_here </blockquote>"
whereas it should become "..lorem ipsum
doloryou_code_h ere</p></blockquote>"
So I finally dug my head deeper into regexp and found the solution:
$replacement = 'mycodehere' . "\$0";
$newStr = preg_replace("/(\<\/\w*\>)*$/s", $replacement, $str, 1);
I am using the code to insert a small nice graphic image after the last
word in the document, often seen in magazines marking the end of the
article. The actual content comes from a CMS.

Greetings,
I have not been able to find the documentation that will allow me to
insert
php code inside the html code in the $message block in the mail() function.
Using the example in the help file:
<?php

$to = "valid@email.add" . ", " ; // note the comma
$to .= $_POST;

Let's say I have a string consisting of n words (where n > 0). I would like
to insert string 'abcd' between the first and second characters of each
word of the string.
I could probably use a combination of explode, implode and substr, but I
was wondering if there is a more elegant way of doing it using regular
expressions?

Hi,
I wanted a web page where I could post code to, and have it appear in coloured formatting based on the context of the code.
Most of the techniques I have seen for this involve complex use of string manipulation where they seek through the string back and forth doing replacements to substitute in the needed HTML code.
I am convinced that this can be done with a few regular expressions. Unfortunately my knowledge of regular...
