I am replacing a string in a text block that has a literal $ in it, and
preg_replace is seeing it as a backreference. Here is what I am using:
foreach($price_ lists as $list)
$x=preg_replace ('/--PRICE-LIST--/',$list,$x,1);
OK, so what this does it is takes each array element and replaces only
the first occurrance of "--PRICE-LIST--" with it. I would have used
str_replace, but I didn't think it should be necessary to create an
array with the same number of elements as $price_list just for a simple
thing like this.
I did, hoever try:
$x=str_replace( '--PRICE-LIST--',$price_lists, $x);
Since the manual page didn't say anything about that case to no avail.
So right now I have the following:
foreach($price_ lists as $list)
$x=preg_replace ('/--PRICE-LIST--/',str_replace(' $','\$',$list), $x,1);
Which compensates for this. However, that is just one case, I cane
forsee others showing up. Does anyone know of a way to make preg_replace
behave as I intend it to? Or does someone have a function for regex-safe
string encoding?
TIA!

Change it to:
foreach($price_ lists as $list)
$x=preg_replace ('/--PRICE-LIST--/', preg_quote($lis t), $x, 1);
And of course, see <http://us2.php.net/preg_quote>

Thanks! I'm surprized that I didn't see that one.

Unfortunately, that didn't work for my application because there is HTML
in it, and it escaped all the < and >. However, After reviewing the
manual page, it looks like I should be OK with only escaping the $ in
the strings.

I've been going mad trying to figure out how to do this--it should be
easy!
Allow the user to enter '\_sometext\_', i.e., literal backslash,
underscore, some text, literal backslash, underscore and, after
submitting via POST to a preg_replace filter, get back
'_sometext_' (i.e., the same thing with the literal backslashes
stripped)

Hi all,
I'm trying to write a regex pattern to use in preg_replace. Basically
I want to put around every line (\n) in this variable.
However, I need to exclude lines that already have brackets or
quotation marks around them as well as lines that start with a
hyphen. Lastly the lines with ** need the brackets before the **,
instead of at the end of the line.
Here is what I have so far - it is close, but I keep ending up with
