[SOLVED] delete last character of string

[asmith]

is there a function for deleteing one or more characters from the  end of a string ?  assuming don't knowing the length of the string .

thanks

strlen always knows the length of any string...

 

<?php
$string = 'somereallylongdrawnoutstring';
$string = substr($string, 0, strlen($string)-2);
echo $string;

Yes

 

<?php 
$strString = "what is your name";

$strString = substr($strString,0,-1);
echo $strString;

?>

 

you can substitude the -1 to the amount of characters you want to delete

Actually, I was in the middle of editing an example of strlen() when you jumped me. I read a little more into his question than you did. Whether he meant it or not, he implied that you need to know the length of a given string up front before you can perform an operation on it. My example used strlen() purposefully to show him how that function works. My aim is to educate wherever possible as priority one, giving a code snippet as priority two.

 

Thanks again for your concern.

I understand therefore I mentioned "No hard feelings"... it was just a comment I am sorry if it has offended you.
