Regular Expressions - Insert Multiple Times

Answer 1

A:

preg_replace('#\!+#s', 'what_ever_you_want', $subject)

Sorry about question but why you used this # and s symbols?

The first character of a PCRE regexp is the delimiter, in this case the pound sign. After the ending delimiter may be placed a number of modifiers which change how the expression functions. In this case, the `s` modifier is being used.

# is delimiter, you can use what ever you want as a delimiter (except regex metacharacters i think, but im not sure) and "s" is a modifier which makes it multi-line compatible.

Answer 2

A:

I figured out out. I cannot believe I didn't see this before. ! is a metacharacter so I need a '\' before it. That's why it wasn't working. Thanks.

`!` is not a metacharacter. `preg_replace('/!/', '.', 'Hello world!!');` => `Hello world..`

Answer 3

+5 A:

Don't you think str_replace would suffice?

$str = str_replace('!','.',$str);

+1 No need for a regex here.

Daniel Vandersluis 2010-09-05 18:23:42

No I need to do regex for other operations.

Camoy 2010-09-05 18:24:58

I still don't see a reason to use regex, given your "With the same number of periods" comment. Note that str_replace can handle more than one character
