[Resolved] mid() - going from asp to php...

[markdw]

Function GetTile(intOS) ' input coords to get base tile filename
	Dim GetTileResult, GetTileCh4
	GetTileCh4 = mid(intOS,4,1)		
	if GetTileCh4 < 5 then GetTileCh4 = 0 else GetTileCh4 = 5 end if
	GetTileResult = left(intOS,3) & GetTileCh4 & "00"	
	GetTile = GetTileResult	
End Function

That is a little function I wrote to round a 6 digit number to the nearest 500. I have re-made this in php using round() but it dosent goive me exaclty the same results as the above. Can someon help me exactly re-create the above in php please?

I firstly need to grab the 4th character. Then if it is lower than 5, change it to 0, or if it is 5 or over, chage it to 5. then join that to the first 3 characters and add to zeros to the end, leaving me with a 6 digit number

Many thanks in advance - Mark

If you do want to do it in a string-processing way, the equivalent for mid(), left(), etc. would be to use [man]substr[/man]. But from your description I think [man]floor[/man] might be closer to what you want. Specifically, (floor($intOS/500)*500)

Fantastic!
Floor sorted it, thanks guys!
