Asheeown Posted March 16, 2011 Share Posted March 16, 2011 I'm making this simple parser that has turned out to be not so simple. Phrases/sentences are encased in apostrophes and parsed but when they CONTAIN apostrophes, slashes are added before it is parsed. For example, if someone entered the sentence (It's a sunny day today.), the output would look like this: 'It\'s a sunny day outside' I add the apostrophes manually on the outside to separate sentences but addslashes before that to escape any existing ones so far. However, my expression below just doesn't cut it, and I can't figure out how to skip over any apostrophes that have the escape character in front of them. $regex = "/'(.*?)'/"; Link to comment https://forums.phpfreaks.com/topic/230814-apostrophes-are-killing-me/ Share on other sites More sharing options...

Asheeown Posted March 16, 2011 Author Share Posted March 16, 2011 That regex sends back an empty array when using preg_match_all. I tried with the example I posted as well and it's the same thing.

JAY6390 Posted March 16, 2011 Share Posted March 16, 2011 Oops you need to escape the escape character twice, like so /'(.*?)(?<!\\\\)'/ Link to comment https://forums.phpfreaks.com/topic/230814-apostrophes-are-killing-me/#findComment-1188261 Share on other sites More sharing options...
