preg_replace help

[JDJones]

I'm having some trouble getting this replacement to work efficiently. I
have the following code:

$thing = preg_replace("( \r\n|\n|\r|\t)" , "", $thing1);

What I want to do now is to get it to remove any semi-colons in the
string as well as replace the new line, carriage return and tab
delimiters. I can't seem to find a way to make the one preg_replace
expression do both. I've had to rely on a second independent
preg_replace statement on $thing to get it to do the semi-colons properly.

Is there a way to combine it all into one statement? Thanks

isn't str_replace better?

<?php
$thing = str_replace(arr ay("\n", "\r", "\t", ';'), '', $thing1);
?>

Your expression works at the moment, but I suspect that's only by accident.
You'd intended those parentheses for grouping, not delimiters, right? DON'T
FORGET THAT PREG_ EXPRESSIONS REQUIRES REGEX DELIMITERS (most commonly a
pair of forward slashes). i.e.

$thing = preg_replace("/[\r\n\t;]/", "", $thing1);

If you're concerned about execution time, you may want to benchmark this
against the str_replace suggested by the other poster. Preg_ is generally
pretty fast, but str_replace might well be the faster in this case.

*head hung low*
I was under the impression that it had to be done as a preg_replace. But
I now see that your str_replace works just as well. One of these days I
may actually get all these PHP things to sink in.

Thank you and CC for the help. I have changed it to the str_replace.
