erase one character from a string

Anon

hi,

i would like to erase a character in a string.
eg:

$buf = "?ita_est?";

How could i just delete the first '?' ?

I would like to have the string "ita_est?" as the result.

Does anyone have a idea how to solve this little probelem ? I could image there is a function for this kind of string operation, but i wasn't able to find a good solution by myself.

I would be glad if someone could help

thanks in advance

Well...... there's lots of string functions, after all there's a whole chapter of the manual devoted to string manipulation. Is it always going to be the first character you want to drop? If so:

  $buf = substr($buf, 1);

will do the trick. Is it always going to be the first occurance of the "?" char? If so it gets a little more involved. String manip. can be as complex or as simple as you need it to be..... if you can provide a bit more detail we can probably help a little more. Otherwise, I've suggest starting at:

You'd be even happier if you just took some time to read the string functions section of the manual.

Too true, too true. Manuals are great, manuals are your friends, they cry at night if you don't read them🙂 That's why I put the URL for the String Functions section in my first post. However, in the interest of good nature (and straight from said manual).....

  $newstring = substr($oldstring, 0, strlen($oldstring)-1);
