Need Help??

I nearly didn't spot that the if condition

/filename\s*=\s*(\S+)/x
[download]

& the (supposedly) equivalent switch condition

/filename\s*=\s*(\S+)/
[download]

aren't the same - the if version has the x modifier.

A user level that continues to overstate my experience :-))

Not supposedly. They are equivalent.	[reply]

... but surely they're equivalent only because there's no extended RE at play ? A user level that continues to overstate my experience :-))	[reply]

Lots of things would make them not equivalent. What's your point? By the way, the "x" modifier has nothing to do with extended regexp features.	[reply]
