I need to detect locations of start and end in several lines of pseudo code.
Basically, if the word "start" or the word "end" has a space or newline before and after, I need to record the match.
The space/newline recognition is important since start or end could be part of the contents that appears between start and end, ie
start start_time = 2 end_time = 5 end
So far tried
preg_match('/((\s)|( *)(start)(\s)|( *))|((\s)|( *)(end)(\s)|( *))/i',
$line, $matches, PREG_OFFSET_CAPTURE);
...and variations.
You can use this regex to capture this block:
(?<= |\A)start(?=\s)[\s\S]*(?<=\s)end(?=\s|\z)
