[PHP] How to remove only the last character?

[Douglas Douglas]

Good day.

Is there any PHP function that removes only the last
character of a string and returns the new string?

I'm looking in the manual and I can't find anything.

Until now I'm doing this:

$var=substr($var,0,strlen($var)-1)

Is this the most efficient way?

Thanks.

Hiya,

Try this, *probably* more efficient but I don't know for sure.

?

$string = 'testing 1 2 3 testing';

echo $string . \n;

$string[strlen($string)-1] = \0;

echo $string . \n;

?

Regards,

Ian Packer

I want to thank you Ian, Zydox and Nicos.

After Zydox response I checked the manual again and
read this part in the substr function:

If length is given and is negative, then that many
characters will be omitted from the end of string
(after the start position has been calculated when a
start is negative)

Sorry to bother you guys, and thanks again.

$new = substr($string, 0, -1);
