PC Regular Expression Delimiters

[Brendan_Nolan]

I know that this is probably a stupid question but...

What exactly is the delimiter for when writing regular expressions? Is it simply to splt the modifiers from the pattern?

Does it matter at all what I use as a delimiter?

[xlordt]

yes it does matter cause the delimiter has special values to it unless you escaped them for example

a{3} # means mach the letter a 3 times ({n})
a+ #means match the latter a 1 or more times (+)
^a # means if the string starts with the letter a (⁾

it would help you if you readup on regular expressions abit

The syntax for patterns used in these functions closely resembles Perl.
The expression should be enclosed in the delimiters, a forward slash
(/), for example. Any character can be used for delimiter as long as
it's not alphanumeric or backslash (). If the delimiter character has
to be used in the expression itself, it needs to be escaped by
backslash.

So yes the delimiter simply splits the pattern from the modifers.

I'm Not quite sure what you are trying to say xlordt, don't use { or } or + or ^ as delimiters?

It's usually a safe bet to stick with forward slashes.
