Re: Re: Replacing first character in a string

Why not just reference the character directly and test against that? It's not much different, but I would guess that it is slightly faster. if ($str{0} == ",") { $str{0} = 0; } Wes On Wednesday, April 30, 2003, at 11:20 PM, Hugh Bothwell wrote:

I wonder if anyone can help me? I have a string something like this: ",.00109863,.00219725,.00329588.... and so on....". If the *first character* in the string is a comma (as in the case above) then I want to replace it with "0,", but I cannot find a way to do it.

Of all the replies, only one was correct, and it was pretty obfuscated. Try this: if (substr($str,0,1) == ",") $str = "0" . substr($str,1); -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
