Have you ever stared at at 45-line script for half an hour to figure out why PHP is getting annoyed with an "unexpected $end" just to figure out that you left a semicolon out of an eval statement?

/me drives head through monitor

What kind of new monitor are you going to get? ;)

yes, yes i have a bloody ; here or a " there can really ++++ you off.

one time i was writing a script to find i had the query returning a result by age when it should have been id me and 3 other folks couldnt figure it out lol (that includes vbulletins scott)

Punctuation is your friend. :)

Yep and then i end up running to scott for help lol!

I was working on a school project (which took 2 weeks) and I had an error which cost me 7 hours to solve.
I tried lots and lots of things, but after those 7 hours (so, at the end of the day) I finally found the error:

Note that there's a " in front of username while there's a ' on the end.

I remember a lot of people staring at me while I was cursing...

That's why I always use single quotes for keys and double-quotes for everything else :p
