One more question, then I'll leave you alone - promise! How simple
would it be to split the two names into 2 vars ($n1 $n2)?

I should get into the habit of listing the assumptions my code makes.
In the above example, the following assumptions are present:
- The target substring (in this example, "<^JIM_JONES>") must *always*
appear at the beginning of the string for the function to perform its task
- The target substring will *always* begin with "<^", will feature a "_"
between the two name elements, and will conclude with ">"
- There will only be two name elements within the target substring (ie will
match "<^JIM_JONES>" and "<^MARY_BETH>" but will not match "<^JIM>" or
"<^MARY_BETH_JONES>")
- The function will only replace the first incidence of the target
substring. In the eventuality that the target substring value appears
multiple times in the string being processed, all other instances will be
left unchanged.
- All other contents of the string being processed can vary without impact
on the function.

Murray

This is a pretty good solution, however for the sake of paranoia about
potentially removing characters that Will may not want targeted by the
function (i.e., what if "<", ">", "^" or "_" legitimately appear later in
the string and are accidentally removed?), I'd do something like the
following:
/", $string, $matcharr);
$string = str_replace($matcharr[0], $matcharr[1] . " " .$matcharr[2]
. ":", $string);
return $string;
}
$string = "<^JIM_JONES> Leicester, 1720. Oxford, 1800 CONFIRMED: meeting at
19.10";
echo replace($string);
?>
One of the small benefits of this solution is that Will doesn't need to know
what is contained in the target substring beforehand.

Murray

The original request was: "the text-to-replace is just in a var named
$text1".
I read that to mean you'd already extracted "<^JIM_JONES>" into $text1

$string = str_replace("_", " ", $string);

Can you give us a pseudo-example of what the string might actually contain? I think both Brian and I took your original message to mean that your string would ONLY contain a value like "<^JIM_JONES>", but from this message I get the sense that the value you're trying to target may be buried in a string with other text on either side?

This is a great help, thanks to both. One question I have though.
How do I just leave the formatting "as is"? In the loop you gave me,
Brian...:
foreach($pieces as $char) {
$first_letter[] = $char{0};
$remainder[] = strtolower(substr($char, 1));
}
$result = array_merge($first_letter, $remainder);
list($frstltr,$lstltr,$frstwrd,$lstwrd) = $result;
$string = $frstltr . $frstwrd . " v " . $lstltr . $lstwrd;
return $string;
}
I can't see how I can disregard strtolower without disrupting the rest
of the function! My problem is $string contains a whole load of text,
the formatting of which needs to be retained...

I knew you could access but I didn't realize your could assign/replace
specific chars like that, i.e. $string{x} =
I can usually work through the logic but am not familiar enough with PHP
to know what's available to work with

Once you'd preg_split()ed the string into component words, you could have simply applied strtoupper() directly to the first character of each word in your foreach loop. As an example: Just thought it was worth mentioning. Regards, Murray -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Definitely not more clever and arguably not more efficient, but a different
way of handling this might be:
)/", "",$string);
$string = str_replace("_", " ", $string);
$string = ucwords(strtolower($string));
$string = str_replace(" ", "-", $string);
