I'm trying to develop a function that can sort through a string that looks like this:
Donny went to the {park|store|{beach with friends|beach alone}} so he could get a breath of fresh air.
What I intend to do is search the text recursively for {} patterns where there is no { or } inside the {}, so only the innermost sandwiched text is selected, where I will then run a php to array the contents and select one at random, repeating process until the whole string has been parsed, showing a complete sentence.
I just cannot wrap my head around regular expressions though.
Appreciate any help!
