In a follow up to pkbarbiedoll’s recent post….

I’m not sure how to learn what the (I think they are called) “special characters” and syntax used in the post.

I was able to find what \s means (and subsequently \t \n \r \0 and \xOB )
From

switchstatement’s reply and link.

 

But how would find all of these (special characters?)…to be able to decipher and use?

• Is there a list somewhere?
• What wording should I use in a search?

I know I’m completely lame…but I saw this somewhere in a sanitize string…and I’m lost

'/(;|\||`|>|<|&|^|"|'."\n|\r|'".'|{|}|[|]|\)|\()/i'
